Rod M has sent me a postcard from Mexico. It dropped through the letter box on Saturday and features Chichen Itza of which I have not previously heard.
Chichen Itza was a major focal point in the Northern Maya Lowlands from the Late Classic (c. AD 600–900) through the Terminal Classic (c. AD 800–900) and into the early portion of the Postclassic period (c. AD 900–1200). The site exhibits a multitude of architectural styles, reminiscent of styles seen in central Mexico and of the Puuc and Chenes styles of the Northern Maya lowlands. The presence of central Mexican styles was once thought to have been representative of direct migration or even conquest from central Mexico, but most contemporary interpretations view the presence of these non-Maya styles more as the result of cultural diffusion.
So now you know. It's Rod's world, we just live in it. I think he may be losing his touch though. He managed to visit Mexico for the whole of January without a civil war breaking out.
Update - Correction.
Twenty-four hours of terror as cartel violence engulfs Mexican city
At least 29 people killed in Culiacán as drug cartel gunmen fight bloody battle to stop transport of El Chapo’s son after arrest.
I was a fool ever to doubt him.
