Mas d’Azil goats

This is one of the most amazing artefacts I have ever seen...Carved from a sperm whale tooth, it depicts two climbing Ibex goats...Found in Mas d’Azil cave (Ariège, France), Middle or Late Magdalenian (13000-10000BC), Piette collection, Musée D’Archéologie Nationale...



"What's so exciting about this depiction of two goats?", I can hear you say. "I mean the cave was full of amazing animal depictions carved in bone...Like this horse head for instance"...


Well...Did you notice that under each goat, there are two groups of 6 incised lines? 12 in total...Why would they be there, I wonder...Could they be representing 12, 29 days moons (like this one depicted on moon shaped boar tusk), of the solar year? 

I talked about these early lunisolar calendars in my post "Calendar"

Hmmm, why would the notches be under Ibex goats depicting climbing a mountain??? Well...Ibex goats in Europe ascend to mountain tops during their mating season, which starts in December, and ends in January typically lasting around six weeks... 

I talked about this in my post "Goat".

Right in the middle of the mating periods of Alpine Ibex is Winter Solstice, 21st of December. And the day after the winter solstice is the beginning of the Capricorn (goat) period, which last from December 22 

If you wanted to have a proper calendar, then that calendar has to be lunisolar...It has to have a beginning fixed in a solar year from which you count your moons...Otherwise it begins to slip as 12x29 = 348, 17 days less than the full solar year of 365 days...

Winter solstice is one such event which occurs every year at the same time and which can be, and was, used as a lunisolar calendar anchor...To prevent your calendar from slipping, all you need to do is determine the day of the winter solstice, and then count 12 moons...

How do you do that. Well that is not really that difficult. 

You find a clear flat piece of high ground from which you can observe sunrises and sunsets. The observatory. You stick a pole into the ground to mark the observation spot. Then as the year passes, every morning and every evening you stand next to the observation pole and observe sunrise and sunset. As you are observing the sunrises and sunsets, you notice that the point where sun rises is not the same as the point where sun sets. The sun rises on the left side of the horizon, travels across the sky from left to right and sets at the opposite right side of the horizon. As days pass you realize that the point where the sun rises moves along the horizon. So does the point where the sun sets. You notice that the sunrise point moves during the spring further and further to the left and the sunset point further and further to the right. So the sun needs to travel longer across the sky and the day is longer and longer and hotter and hotter. Then at some point during the summer the sunrise and sunset points start moving in the opposite direction. The sunrise point starts moving to the right and sunset point starts moving to the left. They get closer and closer to each other, so the sun has to travel shorter distance between the sunrise and sunset and the day is shorter and shorter and colder and colder. 


The point when sun rises in the same place 2-3 days in a row is one of the solstices. Winter solstice if your nuts are frozen solid while you are watching the sunrise, summer solstice otherwise (if you are in continental Europe that is)...

Easy...

Then watch the skies carefully during the extra days after "the end of calendar", wait for the next winter solstice, rejoice and throw a wild solstice party, and then start counting moons again...I talked about these "extra days" in my post "The end of time"

But if you are not fussy and don't care about the exact time of the winter solstice, you can always rely on Ibex goats to start climbing to the mountain tops to start their mating season around the same time every year...All you have to do then is count 12 moons from then...

Soooo....This is why I was so excited when I saw this image...Is this a lunisolar calendar with the Ibex as the beginning of the solar year marker???

  1. Great article. Just one typing error - it's 348, not 248... ;)

  2. I recently discovered your blog, and it is one of the best things I've found on the internet! Thank you for this research. Can I support your work?

  3. It is sad that we have no records of pre-agricultural thought. You do a great job connecting the zodiac signs with the agricultural calendar, but they must have been just as obvious and important to pre-agricultural people, as this post indicates.
