Many people have stood in front of the massive stone monument known as the “Gate of the Sun” in the ancient city of Tiwanaku in the Bolivian Andes.

They admire the craftsmanship of the small carved figures known as “Chasquis” or “Messengers of the Gods” and ponder over the use of the gate as an ancient calendar.

But in fact, the gateway itself is not the calendar, the calendar is a little known row of 11 giant upright stones, now built into a wall which exists just behind the gateway.

Today, there are only 10 stones in the wall and the missing 11th stone lies face down some distance out in the field behind the wall.

When the 11 stones were in their original positions in a row, the sun would set each evening over the row of stones so that priests standing in the centre of the adjacent courtyard could easily calculate the time of the year in a remarkable calendar which divided the year into 20 periods of 18 days and also meshed with a lunar calendar so that three solar years equalled 40 sidereal lunar months which was 2 “zocam” years and even more remarkably it also meshed with a Muisca lunar period of 37 months.

This meant that every 30 solar years was at the same time 20 Muisca Zocam years of 20 sidereal months of 27.32 days and 10 Muisca Acrotom years of 37 synodic months of 19.53 days.

Additionally every thirty years an extra month had to be added to both lunar calendars to keep them synchronised with the solar calendar and this is commemorated in the Gateway of the Sun with thirty Chasquis marking the solar years and forty condor’s heads marking the lunar months.

So the Gate of the Sun is not the actual calendar but the key to operating the calendar and how it works is explained in this remarkable booklet.
