Mai-MON-ides?

The best rainbow.

This gorgeous little illumination shows the Red Sea dividing. The text is from the fifth chapter of Maimonides' commentary on tractate Avot of the Mishnah, which says (translated into English) that the waters "were divided into many paths equal to the number of the tribes, as the appearance of a rounded bow."

One man, Solomon Yedidiah ben Moses of Rome, scribed the entire manuscript in thirteenth century Italy. It's almost entirely in Hebrew, containing translations of texts like Aristotle's Meteorology and Maimonides' Guide for the Perplexed. The whole thing is just a scorcher. You can see all the manuscript illuminations at the British Library's website.
