The World’s Oldest Lunar Calendar

Archaeologists working in the Dee Valley, Aberdeenshire, Scotland have identified what may be the world’s oldest calendar. They also believe the calendar, created as a series of 12 specially shaped pits arranged in a semi-circle and nearly 10,000 years old, may have been maintained and updated until around 4,000 years ago.

Until now the oldest calendars were the Bronze Age monuments found in Mesopotamia. The Scottish calendar predates them by thousands of years, pushing back calendar-making to roughly the end of the last Ice Age. The pits aligned perfectly on the midwinter solstice, adding credibility to the claim that this is an actual lunar calendar.

The pits are even shaped to reflect the various phases of the moon. Waxing, waning, crescents and gibbous phases are all present in their proper positions and arranged in a 164-foot (50 meter) long arc. The center pit, representing the full moon, is circular, roughly 7 feet (2 meters) across.
The pits were first discovered in 2004 on aerial photographs but only recently studied using remote-sensing technology. Specially developed software was used to work out the positions of sunrises and sunsets experienced 10,000 years ago.

It seems obvious that the early people who created this calendar so long ago needed to know about the changes of seasons. It would have helped them to know when game might be available, when crops could be harvested, and even to predict when salmon and other migrating fish could be harvested.

Once again, our ancient ancestors have left evidence of their astronomical knowledge and their ability to take advantage of that knowledge.

The World’s Oldest Known Poison

Border Cave, located on the border between South Africa and Swaziland, has produced surprise after surprise for researchers analyzing layers representing literally tens of thousands of years of occupation. One of those surprises is the evidence of the deliberate use of poisons by hunters over 44,000 years ago

Researchers dated a lump of beeswax mixed with a toxic resin to about 35,000 years ago. They believe it was used to attach stone points to the shafts of arrows or spears. Coincidentally, this is also the oldest evidence for the use of beeswax.

Researchers also dated a wooden stick with marked with scratch marks up and down its length and dated at about 20,000 years old. Traces of ricinoleic acid, the notorious poison found in castor beans, were found during a chemical analysis of residue on the stick. The stick closely resembles poison applicators used by the people of the early San culture, which was emerging at about that time.

Bows and arrows were also thought to be emerging about 20,000 years ago and there is a good possibility that they were coming into use when the applicator was created. The thin, small points found in the younger debris at Border Cave resemble the bone points produced by the San people, who are known to have used poison-tipped bone points on their arrows to help bring down medium and some large-sized game.

The World’s Oldest Grape Vine

An ancient vine in Maribor, Slovenia, has been authenticated by experts as the world’s oldest producing grape vine. It is at least 400 years old, and its age has been confirmed by experts in both Paris and Slovenia. It also appeared in paintings known to have been completed between the years 1657 and 1681 which show that this elderly vine was already mature at the time.

Its fruit is also one of the oldest domesticated noble wine grapes known in Slovenia. Its descendants are now found on nearly every continent of the world.

Its owners still produce wine from Old Vine. They bottle anywhere from 35 to 55 kilograms annually, bottling the product in more than 100 2.5 decaliter glass bottles per year. The annual Pruning of the Old Vine is a ceremonial event. The scions are naturally highly sought after and the bestowal of the ancient plant’s scion is cause for celebration by the lucky cities chosen to receive one as a gift. Another annual ceremonial involves the harvest of its grapes which takes place as part of the Old Vine Festival.

Old Vine is registered in the Guinness Book of Records. This revered plant is carefully tended and watched over, and is showing no signs of weakness.

Old Vine might provide the perfect excuse to visit Maribor. A lively tourist industry has grown up around the old vine. Sightseers can visit the Old Vine House itself, visit wine cellars and museums, and just enjoy the town and its surroundings. All in all, Old Vine sounds like a good excuse to take in a part of traditional Slovenia.

The World’s Oldest Bone Tumor

This "world’s oldest" also goes to the Neanderthals, but it’s not really happy news. It seems that a 120,000-year old Neanderthal was the victim of a bone tumor that plagues people even today. It is actually 100,000 older than the previous record-holder.

This particular tumor was a benign fibrous dysplasia found on a rib recovered from the well-known Neanderthal site at Krapina, Croatia that is arguably of one of the richest Neanderthal sites ever found. It is identical to its modern-day descendants. One unusual aspect of this tumor is that Neanderthals did not generally have a long life-span. Tumors such as this one generally only appear as an individual ages.

While many Neanderthals died as a result of accidents or other types of violence, we now know that they also suffered from many of the same diseases which afflict people today. Evidence has been found that these early people suffered from tuberculosis, arthritis, periodontitis and other potentially deadly diseases. Some of this evidence has been found in individuals who lived 100,000 or more years ago.

We sometimes think of Neanderthals as living in an idyllic world where they were free to hunt and roam where they liked without suffering the ravages of disease. Mounting evidence indicates that this was not always the case. It also seems clear that at least some so-called "modern" diseases may have evolved much earlier than has been generally believed.
