The Guide for the Perplexed
Some time around 1275 he taught "The Guide for the Perplexed" and his Kabbalah in a few cities in Greece. He wrote the first of his prophetic books, "Sefer haYashar" ("Book of the Upright/Righteous"), in Patras in 1279. That same year he made his way through Trani back to Capua, where he taught four young students.
