My thanks to David Higham who attended a course last Saturday and sent in this image of the Caracol Observatory Tower at Chichen Itza and also for drawing my attention to the fact that the later additions are aligned differently, possibly accounting for the need to track different celestial objects or even for differences due to the precession of the equinoxes.

One of my secret hopes when launching the beginner’s courses was that it would attract a varied gang. I am delighted to be able to write that the early indications are very promising. Those walking away with a certificate already include a submariner and Royal Navy officer as well as a brace of desert-crossers, holidaymakers, engineers and writers.
This really adds to the day as everyone’s varying backgrounds and experiences allow them to offer fresh perspectives on new and familiar territory. It also means that the learning never stops for me too. On the course last Saturday I learnt something new about archaeoastronomy and the ancient observatory at Chichen Itza in Mexico and found out about the Geochron clock, which shows in real time the areas of earth that are in light and dark.
