Unusual-ology: Ancient Greek and Roman “Entrance to Hell” discovered.

Unusual-ology is a new post type which focuses on weird new articles/science areas that have cropped up and caught my eye.

Italian archaeologists from the University of Salento, led by Francesco D’Andria, working at a Greco-Roman site of ancient have discovered the ‘Entrance to Hell’.

ImageHieropolis, known today as Pamukkale, Turkey – where the “Entrance of Hell” has been located.

This ‘Entrance to Hell’ has been discovered in Hierapolis, known today as Pamukkale, in Turkey.  Francessco and the fellow archaeologists were able to stumble upon the entrance of the temple by tracing the path of the hot springs through the ancient site. The temple, identified as the Ploutonion, has been linked to Hades and correctly identified due to an ‘engraved dedication’ to Pluto above the gate. The temple was built over a cave and underground in the thermally active area. Ploutonion was the worship ground for many ancient pilgrims who would travel to celebrate their gods and bathe within the hot springs that surround the area.

The reason why the Ploutonion has been called the ‘Entrance to Hell’ is due to the writings of the Greek geographer Strabo. Strabo mentions about the “opening of sufficient size to admit a man, but there is a descent to a great depth… The space is filled with a cloudy and dark vapour, so dense that the bottom can be scarcely be discerned.” These documents explain that the cloudy, dark vapour has caused many animals that enter to die instantly. Strabo wrote that Bulls which had entered the Ploutonion “fell down and were taken out dead” and sparrows which were thrown inside “immediately fell down lifeless.” The Ploutonion’s poisonous vapour still survives today as many dead birds have been found on this site during modern excavations. The presence of the dead birds has helped convince the archaeological team that this is in fact Ploutonion’s true ‘entrance to hell’.

Unusual-ology: Lettuce, an ancient Egyptian sex symbol?

Unusual-ology is a new post type which focuses on weird new articles/science areas that have cropped up and caught my eye.

Can this key ingredient to salads actually be considered a sex symbol? Well Salima Ikram, an Egyptologist from the American University of Cairo, has claimed that lettuce was viewed as an aphrodisiac by ancient Egyptians, where they also used it as a phallic symbol.


Min – the Egyptian god of fertility and lover of lettuce.

So how did a distant species of our modern day lettuce become a sexy vegetable? On numerous tomb walls, dating back to 2,000BC, there are images of lettuce which have been connected to the Egyptian god of fertility – Min, who can be found depicted with an erect penis on numerous hieroglyphs. It is thought that lettuce was Min’s favourite food, and this vegetable helped him perform sexual acts without becoming tired. Many ancient Egyptians wouldn’t have utilised lettuce in meals like we commonly do, but often as an aphrodisiac.

Unusual-ology: ‘Vampiric Burials’ – The archaeological evidence that supports the supernatural myths.

Unusual-ology is a new post type which focuses on weird new articles/science areas that have cropped up and caught my eye.

A recent news story, which can be viewed here, has brought to the attention of the public the topic of ‘vampiric burials’, due to the discovery of a 16th/17th century ‘vampiric burial’ in Poland.  These burials have been linked to vampire activity due to the unconventional layout of the skeletal remains – the occupants of the graves had been decapitated with their head placed between their legs. This activity of decapitating a suspected vampire had evolved from the European folk belief that decapitation is the only way to ‘keep the undead dead’. But this is not the first instance of the discovery of these superstitious burials.

Vampire Burials - Decap

The occupants of the graves had been decapitated with their head placed between their legs.

Another ‘vampiric burial’ was found in Venice during a research project on mass graves located in Nuovo Lazzaretto, where the corpses were from numerous plague deaths. One skeletal remains that stood out was that of a woman. The peculiar thing about this corpse was that a brick of moderate size was placed within her oral cavity, keeping her mandible wide open (Nuzzolese & Borrini, 2010).

The positon of the brick was ruled out to be accidental, it wasn’t a piece of sediment that just happened to have fallen into place – it had been purposely placed there, but why? Nuzzolese & Borrini (2010) hypothesise that this is part of a symbolic burial ritual of which the gravediggers practice when there was a suspected vampire – who they thought could have been the cause for the plague ravishing their village.

Europe isn’t the only place to have encounters with ‘vampire graves’. A journal dating back ten years addressed America’s, more specifically New England, vampire folk beliefs using bioarchaeological and biocultural evidence. Sledzik & Bellantoni (1994) examined how folk beliefs associated with death and disease can impact archaeological records from their use of unusual post-mortem actions. In this study Sledzik and Bellantoni focused on a single 18/19th century male skeleton, known as J.B, aged between 50 to 55 years old. They chose J.B due to his skeletal remains being rearranged; the bones of his chest disrupted and his skull femoral placed in a “skull and crossbones” position.  J.B had died from either tuberculosis or a pulmonary infection – which was interpreted as tuberculosis, also known as consumption at the time of death.  It’s hypothesised that fellow family members, seven years later, contracted tuberculosis. The family assumed that the deceased male had returned from the dead and had ‘fed’ on them. From this notion, the family exhumed the corpse of J.B to kill the ‘undead’, keeping with the New England belief of killing a vampire by burning their heart. When they exhumed J.B. and found his body decomposed and missing his heart – which could then not be burnt – they decided the best course of action was to disrupt his corpse to stop reanimation.

So the discovery of the Polish vampire graves may have shot vampire burials into the limelight, but this isn’t the first archaeological case of superstitious vampire burial rituals, and it won’t be the last.

Unusual-ology: How to get A-Head in Medieval England.

 This is a recap of lecture which I attended during my degree. It focused on an extremely weird case study which the lecturer had been presented with, a skull which had preserved soft tissue with ‘links to medieval witchcraft’. 

Within this lecture we were presented with a case study of a skull which had preserved soft tissue. The lecturer talked about how he had stumbled on this rare artefact in a peculiar museum which dealt in Wiccan and witchcraft. There it had a story allocated to it to entice an audience and raise curiosity.

This story was of medieval origins where brutal executions took place. This skull belonging to an execution victim was stored in a Church inside a wooden box covered in numerous markings of figures in communal scenes; these figures are depictions of ‘Green Men’. Intrigued by these mysterious figures and why they appeared on a wooden box along with scrape marks, I decided to do some research of my own. I found that ‘Green Men’ are deities of nature Gods which are often found within Churches and a symbol of pre-Christian religions often in Pagan origin. Could this skull have been kept as a relic? Does it belong to an important figure from medieval times? But after the War was it stolen from the Church and sold onto this museum?

What was peculiar about it was the preserved tissue only found on bodies in extreme conditions such as heat or cold or bodies submerged in bogs. The initial thought was “Could this marvellous story be true? It is a modern day fake, or is it something totally different? Or is it actually a mummy?”

What first stood out was that the skull had remains of eyes which mummies do not possess at the time of burial. Also from examining the skull and comparing the skulls to known parameters it was discovered to be the skull of a 35 to 45 year old woman. More tests were run using modern day technology such as MRI scans and CT scans, the MRI scan failed to show anything due to the lack of hydrogen atoms within the skull due to the dehydrated state it has deteriorated to. But there were surprising results from the CT scan which showed that there was a grey area in the back of the skull, could this be preserved brain? It turned out it was actually tree sap, which backs up the theory that this skull is actually a mummy. Egyptians used pine resin to preserve the bodies as its more ‘sacred’ than glue. There was also evidence that the septum of the skull had been broken by something, which is common in the procedure for mummification. To get a definitive answer to this riddle the final step was to use carbon dating; this helped determine that the skull is in fact a mummy and not a medieval relic or execution victim.

The use of all these modern technologies, theories and knowledge gained from previous case studies helped shine a light on the true origins of this skull. Other artefacts have been found to be something they’re not and are now being traced back to their true beginnings and having a new story assigned to them, for the future generations to be marvelled just as I was during this riveting lecture.

Unusual-ology: The Churkey: Half Turkey, Half Chicken?

Unusual-ology is a new post type which focuses on weird new articles/science areas that have cropped up and caught my eye.

I stumbled upon a very interesting article about a type of bird which has been dubbed as a ‘churkey’. The instant I saw the title I was immediately intrigued and felt I should write a post on these bizarre creatures.

The Transylvanian naked neck chicken has been recently assigned this nickname due to its unusual appearance; the ‘churkey’ has the body of a chicken but has the neck of a turkey.

Scientists at Edinburgh University, led by Dr Denis Headon, have set out to understand what has caused the chicken to have this unique appearance. The scientists have proposed that its appearance is caused by genetic mutation which was enhanced by a vitamin A-derived substance that is produced around the bird’s neck. Researchers were able to identify this as the protein BMP12 after obtaining DNA samples from numerous naked neck chickens from Hungary, France and Mexico (BBC, 2011). This protein causes the feather production to be suppressed around the neck area. The mutation was first found in domestic birds in Romania around a hundred of years ago. It is suggested that the loosing of feathers around the birds necks help the bird to remain cool in warm climates just like Ostriches (National Geographic, 2011).

This proves that mutations in animals are not always bad and from this example it has helped scientists understand developmental biology even more. This research could also have practical applications such as to produce poultry that can withstand hotter climates such as those in the third world countries.
