  Not only Aristotle’s works were paraphrased; there are Christianizing paraphrases of Proclus’ Three Treatises on Providence (the latter have since been lost in the original Greek) by Isaac Sebastokrator (1093–after 1152) and of Epictetus’ Encheiridion (no fewer than three of them, all of uncertain date; one of them, composed and provided with a commentary no later than 960, when the oldest manuscript was copied, seems to have enjoyed considerable popularity in the 13th and 14th centuries: Boter 1999, 197–256). One may also note a paraphrase of Ptolemy’s Tetrabiblos sometimes ascribed to Proclus, written before the end of the 10th century (Bydén 2003, 352).
