Here's Thomas Jefferson's full personal library, as we understood it to exist with a number of placeholders for volumes that are missing or have been recorded as destroyed.
This was an incredible place to spend some time - I think I was here for about 30 minutes and surveyed his rhetoric and oratory books. Here are some observations:
Roman books were in Latin - he had the expected Cicero works, but also an edited version of Quintilian in Latin.
He had Greek rhetoric books in French, including the complete works of Isocrates in multiple volumes. That got my interest.
He had a number of oration and oratory/public speaking books of the time, many from the 16th century that were the standard English oration books.
He had no English translations of any of the ancient sources.
What should we make of all this?
