Until c.1450, the only Plato was the Timeaus and some scattered partial translations.

Modern philosophy courses tend to give equal weight to Aristotle and Plato (with a side order of Socrates), but for most of Western history the only pre-Christian philosopher that anyone cared about was Aristotle, who was often simply referred to as "The Philosopher". Plato was largely ignored and forgotten until there was a burst of scholarly interest in him in the 19th century.

This is really not true, sorry. Plato was huge in the Renaissance and his academy ran in Athens (not continuously) from about 400BC-550AD. Platonism had a major influence on the formation and reception of Christianity and Islam, as well.

You may be right, I'm very far from being an expert. Was just repeating something I read somewhere.
