A woman buried with weapons in tenth century Hungary.

The concept of 'warrior women' has fascinated historians, archaeologists, and the wider public for a long time. Many examples of potential 'warrior women' from archaeological sites have been put forward over the years, in the form of women buried with weapons and/or armour. However, gender assignment is often difficult in archaeological contexts, as is determining the relationship between the individuals within graves and the goods buried with them, particularly when the remains are fragmentary. Where a person is buried with a single weapon or piece of armour this is as likely to be a talismanic object or mark of social status as it is an indicator of their ever having held a military role.

A number of female burials with weapons have been reported in Hungary's Carpathian Basin, dating from the Sarmatian Period (1st–5th centuries AD), the Gepid Period (second half of the 5th century–567 AD), the Langobard Period (510–568 AD), and the Avar Period (ca. 567–9th century AD). However, typically only a single arrowhead, small piece of chainmail, or similar isolated item has been found in the grave, which is significantly less than is found in male 'warrior burials' from the same cultures, making it unlikely that these represent female warriors.

The Maygars, or Hungarians, migrated from the steppes of Eurasia to the Lower Danube region around 830 AD, subsequently reaching the Carpathian Basin by the late nineth or early tenth century. They soon came to control the area, forming the Kingdom of Hungary at the end of the tenth century. During this time, Hungarian mounted archers gained a fearsome reputation, both within the Carpathian Basin and in conflicts across much of the rest of Europe. Hungarian warrior burials are common from this period, with warriors found buried with a range of weapons including axes, spears, sabres, swords, and swords with sabre hilts, as well as composite bows, arrows, quivers, and bow-cases. Archery equipment is far more ubiquitous in these graves. However, our understanding of these burials is limited by the preservational conditions in the Carpathian Basin, which mean that in most cases only inorganic parts of weapons and equipment have survived, and an apparent lack of any correlation between the presence and quantity of grave goods and the social status of the person they are buried with.

In a paper published in the journal PLOS One on 26 November 2024, a team of archaeologists led by Balázs Tihanyi of the Department of Biological Anthropology and the Department of Archaeology at the University of Szeged, and the Department of Archaeogenetics at the Institute of Hungarian Research, describe a woman buried with weapons from the tenth century Sárrétudvari–Hízófóld Cemetery in Hajdú-Bihar County, Hungary.

The Sárrétudvari–Hízófóld Cemetery, close to the village of Sárrétudvari in Hajdú-Bihar County, was excavated in 1983-85, and has since been effectively destroyed as an archaeological site by intensive agriculture. The site contained a small number of burials dating back to the Bronze Age, and 262 graves dating from the tenth century AD. The skeletons of 263 individuals were recovered from the 262 graves excavated, with another two individuals identified but two fragmentary to be recovered. Of these individuals, 101 were identified as sub-adults, and 162 as adults. 

An initial assessment of the individuals from the Sárrétudvari–Hízófóld Cemetery, based upon morphological examination of their skulls and post-cranial skeletons, determined that 70 were female and 85 were male, with the remainder impossible to classify. A subsequent analysis based upon examination of the pelvis only (thought to be a more reliable technique) determined that 52 of the skeletons were female and 69 were male, with a larger proportion of undiagnosable remains. 

The majority of the graves have west-east orientation (i.e. head to the west, feet to the east), although some are orientated north-south, and a smaller number south-north. Most of the individuals were buried flat on their backs in an extended position, although two had bent knees. 

A wide range of grave goods were buried with the individuals in the Sárrétudvari–Hízófóld Cemetery. These include items of jewellery such as penannular hair rings, earrings, strings of beads, bracelets, and finger rings, clothing elements such as belt buckles, bell buttons, and broaches which would have been used to secure dresses, knives, fire-lighting tools, and riding-related items, such as stirrups, bits, fragments of saddle, and even horse bones. Notably, 58 of the individuals were burried with weapons, a far higher proportion than is seen in other known cemetery-sites in the Carpathian Basin in the same period. These weapons include sabres and axes, as well as many archery-related items, such as arrowheads, traces of quiver, and antler bow plates.

One of these armed burials was  Grave No. 63, located at the western end of the cemetery, which contained an individual buried with a southwest-northeast orientation, lying on its side, with knees bent. This individual was buried with a range of grave goods, including a silver penannular hair ring near the left part of the occipital bone, three bell buttons (one positioned beneath the skull, another beneath the right clavicle, and the third close to the knees), a string of beads near the left clavicle, including faience beads with blue eye-shaped inlays, yellow and white semiprecious stone beads, and segmented glass beads in various colours, an 'armour-piercing' arrowhead found at the distal end of the grave pit (several iron fragments possibly belonging to further arrowheads were also found in the soil of the grave), fragmented iron parts of a quiver situated near the left side of the skeleton from the shoulder to the toes, and an antler bow plate with convex sides and peaked ends located near the hip and the left hand, which was possibly being gripped by the individual when buried.

The individual from Grave No. 63 (SH-63) has a skull with a reasonably well-preserved cranium, but lacking most of the face, of which only the mandible, fragments of the two maxillae, and the left zygomatic bone remain. More than 50% of the post-cranial skeleton is present, but the bones of the spine, sternum, and pelvis are mostly represented by bone fragments. SH-63 has been determined to be an adult on the basis that all of the bones which would be expected to have fused in an adult individual are fused, and the thinness of the bones has been taken as an indication that this was an older individual, although it was not possible to make a more precise age estimation.

The poor preservation of the skeleton. and in particular the pelvis, of SH-63 made it difficult to determine the individual's sex by morphological means. The skull did appear to show some feminine traits, but this was not deemed sufficient to assign a sex to the skull by previous studies. Tihanyi et al. were able to extract genetic from a tooth, one humorous, and the petrosal process of the temporal bone. All three of these indicate that the individual was female, the sample from the pars pretrosa with sufficient confidence to rule out the possibility of the individual being male.

(A) A very small mastoid process; (B) A smooth frontal contour with little or no projection of the glabellar area; (C) Complete absence of nuchal crest with a smooth external occipital surface; and (D) A smooth mental eminence with slight projection above the surrounding bone. Luca Kis in Tihanyi et al. (2024).

Examination of the skeleton of SH-63 revealed a number of signs that the individual was suffering from osteoporosis, notably bone fragility, traces of a reduced trabecular system in the vertebrae, an increased diameter of the medullary cavity in the long bones, thinning of cortical bone in both the skull and postcranial elements, and several antemortem bone fractures. Since osteoporosis is a condition which predominantly affects older women, this could be another indication that SH-64 was female, although Tihanyi et al. are careful to note that the observed conditions are only indicators of the disease, not enough for an absolute diagnosis. Previous studies of skeletons at Sárrétudvari–Hízófóld have found six other possible cases of osteoporosis, five affecting skeletons confidently assigned as female, and one affecting an individual of unknown sex. No instances of confidently male skeletons with symptoms of osteoporosis have been found.

The skeleton shows a number of signs of injuries having been suffered in life. These include a possible two-part neck fracture to the right humerus, an injury most commonly associated with an accidental fall onto an outstretched arm. Such injuries are most commonly seen in adolescents and the elderly, with older women suffering from osteoporosis being particularly vulnerable. 

Changes observed on the proximal end of the right humerus, at the level of the surgical neck. (A) Lateral and anterior views; (B) Anterior and medial views; and (C) Medial and posterior views. Luca Kis in Tihanyi et al. (2024).

Another fracture is present on the right scapula, with two parts of the bone having apparently healed without rejoining, producing new secondary facets which faced one-another. The left scapula also shows signs of a fracture, although in this case it appears to have healed more normally. Fractures to the scapula are unusual, and are generally associated with older individuals, as in younger people the scapula tends to be well-protected by overlaying muscle. Again, such injuries are generally associated with falls, and an individual with osteoporosis would be more vulnerable to such injuries.

Note: the glenoid cavity is in the upper left corner of the photo; and (B) The margins of the two bone fragments forming a secondary facet. Luca Kis in Tihanyi et al. (2024).

Signs of traumatic injury in life are quite common in male skeletons from Sárrétudvari–Hízófóld, but relatively unusual in females, suggesting the two sexes had very different lifestyles. Multiple injuries, and in particular injuries to the arms, are particularly common on male skeletons buried with weapons or riding equipment. Thus, although the injuries to SH-63 are consistent with a diagnosis of osteoporosis, they are also typical of the injuries seen in individuals buried with weapons and riding equipment. 

Interestingly, SH-63 also showed asymmetry in the development of the tendon and muscle attachments, with the right side being more developed than the west, sugesing a lifetime spent carrying out activities which promoted such asymmetric development. This has previously been recorded in male skeletons from Sárrétudvari–Hízófóld, and has been theorised to be associated with practice with weapons. 

The way in which SH-63 was buried is also interesting. The southwest-northeast orientation of the grave is at odds with the majority of the graves at Sárrétudvari–Hízófóld, but it is by no means unique; there are several other graves with this orientation, the majority of which are at the western end of the cemetery, where SH-63 was found. Notably, most of these other southwest-northeast orientated graves also contain weapons. SH-63 is also one of two individuals buried on one side with flexed knees at Sárrétudvari–Hízófóld; all others being buried on their backs with limbs extended. The other such individual, SH-69, has previously been determined to have been female, and was buried with a silver penannular hair ring, two bronze finger rings, and a knife, but no weapons or other potential military equipment. Some previous studies of other sites from the same period within the Carpathian Basin have suggested that bodies buried in a flexed position tend to have less grave goods than those in an extended position, and it has been proposed that such individuals may have been slaves. However, Tihanyi et al. could find no study which has caried out a systematic analysis of this phenomenon, and suggest instead that is may relate in some way to the sex of the individuals buried this way, although, since the majority of female burials are also on their backs in an extended position, it is unclear how.

(A) Silhouette of the skeleton of SH-63; (B) Illustration of the burial based on archaeological, anthropological, and archaeogenetic data. Luca Kis in Tihanyi et al. (2024).

Thus individual SH-63 appears potenrially to have been a woman both buried with, and practiced in the use of weapons, who developed a number of traumatic injuries later in life, either due to this unconventional lifestyle or to the onset of osteoperosis, or some combination of both. However, Tihanyi et al. are careful to point out that the poor preservation of SH-63 means that this interpretation cannot be taken as proven.

The Ursid Meteor Shower.

The Ursid Meteors are expected to peak at about 10 pm GMT on the evening of Sunday 22 December this year, with the shower being potentially visible to some extent between Sunday 17 and Monday 26 December.  The shower is typically best seen between midnight and dawn from anywhere in the Northern Hemisphere (it is difficult,if not impossible, to view it from the Southern Hemisphere). The extent of the shower is variable, some years producing over 100 meteors per hour at its peak, others less than 10. The peak of this years shower coicides with the Third Quarter Moon, also on 22 December, so viewing may be somewhat impaired, as glare from the Moon can hinder the viewing of meteors. The meteor shower gets its name from the constellation of Ursa Minor, in which it appears to originate.

Meteor streams are thought to come from dust shed by comets as they come close to the Sun and their icy surfaces begin to evaporate away. Although the dust is separated from the comet, it continues to orbit the Sun on roughly the same orbital path, creating a visible meteor shower when the Earth crosses that path, and flecks of dust burn in the upper atmosphere, due to friction with the atmosphere.

The Ursid Meteor Shower is caused by the Earth passing through the tail of Comet 8P/Tuttle, and encountering dust from the tail of this comet. The dust particles strike the atmosphere at speeds of over 200 000 km per hour, burning up in the upper atmosphere and producing a light show in the process. The Earth does not need to pass close to Comet 8P/Tuttle for the meteor shower to occur, it simply passes through a trail of dust from the comet's tail that is following the same orbital path. Comet 8P/Tuttle visits the Inner Solar System once every 13.6 years, last doing so in 2021.

Comet 8P/Tuttle was discovered by Horace Parnell Tuttle on 5 January 1858. The designation 8P/Tuttle indicates that it was the eighth comet discovered (people have known about comets for thousands of years, but it was only realised that they were objects orbiting the Sun, which could be repeatedly observed and predicted, in the mid-eighteenth century), that it is a Periodic Comet (comet with an orbital period of less than 200 years) and that it was discovered by Horace Parnell Tuttle.

Comet 8P/Tuttle has an orbital period of 4972 days (13.6 years) and a highly eccentric orbit tilted at an angle of 55.0° to the plain of the Solar System, that brings it from 1.03 AU from the Sun at closest perihelion (103% of the distance between the Earth and the Sun) to 10.4 AU from the Sun at aphelion (10.4 times as far from the Sun as the Earth or slightly outside the orbit of the planet Saturn). As a comet with a period of less than 20 years, 8P/Tuttle is considered to be a Jupiter Family Comet.

This means that 8P/Tuttle has occasional close encounters with the Earth, with the last thought to have happened in January 2008 and the next predicted in December 2048. The comet also has occasional close encounters with the planets Jupiter, which it last came close to in December 1995 and is next predicted to pass in September 2078, and Saturn, which it last came close to in February 1930 and is expected to pass again in February 2107. Objects which make close passes to multiple planets are considered to be in unstable orbits, and are often eventually knocked out of these orbits by these encounters, either being knocked onto a new, more stable orbit, dropped into the Sun, knocked out of the Solar System or occasionally colliding with a planet.

Magnitude 7.3 Earthquake to the west of Efate Island, Vanuatu.

The United States Geological Survey recorded a Magnitude 7.3 Earthquake at a depth of 57.1 km, roughly 30 km to the west of of Efate Island, Vanuatu, slightly after 12.45 pm local time (slightly after 1.45 am) on Tuesday 17 December 2024. The initial event has been followed by a number of large aftershocks. At least fourteen people are known to have died as a result of the Earthquake, with more than 200 more injured. Many buildings, including hospitals on the island have been damaged, as have several important bridges, and seeveral major roads are reported to have been blocked by landslides.

Vanuatu is located on the southwestern fringe of the Pacific Plate, close to its boundary with the Australian Plate, which is being subducted along the New Hebrides Trench, to the west of the islands. The subducting Australian Plate passes under the islands of Vanuatu as it sinks into the Earth, causing Earthquakes as the plates stick together then break apart as the pressure builds up. As the plate sinks further it is partially melted by the heat of the friction combined with that of the Earth's interior. Some of the melted material then rises through the overlying Pacific Plate, fuelling the volcanoes of Vanuatu.

The December Solstice.

The December (or Southern) Solstice this year falls on Saturday 21 December this year, with the Sun reaching its southernmost point in the sky at 9.20 am GMT. This is the shortest day of the year in the Northern Hemisphere, where it is known as the Winter Solstice and the longest day in the Southern Hemisphere, where it is known as the Summer Solstice. At very high latitudes the sun may not rise (Northern Hemisphere) or set (Southern Hemisphere) for several weeks on either side of the Southern Solstice.

The solstices are entirely a product of variation in the Earth's rotation on its axis, which is at an angle of 23.5° to the plain of the Earth's orbit about the Sun. This means that in December the Earth's Southern Pole is tilted towards the Sun, while the Northern Pole is tilted away from it. This means that around the Southern Solstice the Southern Hemisphere is receiving radiation from the Sun over a longer part of the than the Northern, and at a steeper angle (so that it to pass through less atmosphere to reach the planet), creating the southern summer and northern winter.

The solstices are fairly noticeable astronomical events, and tied to the seasons which govern the life cycles of life on Earth, and they have been celebrated under different names by cultures across the globe, but most notably by those at higher latitudes, who are more profoundly affected by the changes of the seasons.

Florissantia sp.: A fossil flower from the Early Eocene of Rajasthan.

The Malvaceae first appeared in the Cretaceous in North America, and have achieved a global distribution today, most notably as a significant component of almost all tropical forests. The genus Florissantia shows a number of features associated with different extant subfamilies of the Malvaceae, and is known from the Middle Eocene till the Miocene of western North America, with specimens known from British Colombia, Colorado, Montana, Oregon, and Washington, as well as a single specimen being known from the Sikhote Alin mountains of the Russian Far East.

In a paper published in the journal Botany Letters on 21 October 2024, Ashif Ali and Mahasin Ali Khan of the Palaeobotany, Palynology, and Plant Evolution Laboratory at Sidho-Kanho-Birsha University, and Raman Patel and Rajendra Singh Rana of the Department of Geology at Rauthan Hemvati Nandan Bahuguna Garhwal University, describe a specimen of Florissantia from the Early Eocene Palana Formation of Rajasthan, India.

The specimen comes from the Laminate Maroon Shale Bed of the Palana Formation, which is exposed at the Gurha Open-cast Lignite Mine at Bikaner in northwest Rajasthan. It is preserved as part and counterpart on a piece of a piece of split- laminated shale, which has been further exposed by micro excavation of successive layers of the rock with fine needles under a dissection microscope. 

(a) Map of Rajasthan showing the location of the Gurha opencast lignite mine (red star) Bikaner Rajasthan, India; (b) view of the fossil locality. Ali et al. (2024).

The preserved fossil is a star-shaped flower about 13 mm in diameter (sgnificantly smaller than any other member of the genus), with a calyx made up of five fused and rounded sepals of roughly equal length; the petals are missing. Importantly, the sepals each show numerous prominent veins, the pattern of which is used by Ali et al. as a diagnostic tool to place the specimen in the genus Florissantia.

(SKBU/PPL/R/F/01A, part); (b) magnified image of the specimen showing thick filaments (marked by red arrows) surrounding the compressed, carbonaceous central area; (c) enlarged view of a single calyx lobe showing prominent parallel (marked by blue arrows) and radiating reticulate (marked by white arrows) venation; (d) counterpart of fossil flower of Florissantia sp. (SKBU/PPL/R/F/01B); (e) central area of figured in higher magnification; (f) line drawing of (c) showing parallel (marked by blue arrows) and reticulate (marked by red arrows) venation, Scale bars are 2.5 mm for (a), (b), (d), and (e) and 500 μm for (c) and (f). Ali et al. (2024).

The Palana Formation of Rajasthan has been dated to between about 55 and 52 million years before the present on the basis of palynological data (fossil pollen). This Early Eocene date makes the Bikanar specimen the oldest representative of the genus Florissantia, which together with its unexpected location, potentially makes the specimen highly significant. 

Line drawings of the Bikanar specimen and earlier reported extinct fossil flower species: (a) Bikanar fossil flower of Florissantia sp.; (b )fossil flower of Florissantia ashwillii from the Oligocene of Oregon; (c) fossil flower of Chaneya membranosa from the Miocene of Poland; this appears similar to Florissantia spp, but has unequal sepals. Scale bars are 5 mm. Ali et al. (2024).

The Palana Formation was laid down on the shores of an ancient lake, which is consistent with other locations where members of the genus Florissantia have been found. Other members of the genus are known from lake-associated Floras in tropical, subtropical, and temperate environments, often with some volcanic input; although the presence of volcanic ashes helps to preserve fine structures such as flowers, so it is possible that this connection with volcanic input reflects preservation bias rather than an environmental preference of the living plants.
