Claim: Written in "clear, concise language" and the oldest illustrated Yiddish-language book, the Paris Book of Customs came into the possession of Cardinal Richelieu some time after 1632.
Evidence: The Paris Book of Customs is a Sefer Minhagim (book of religious customs) and the oldest illustrated Yiddish-language book. Originally owned by a single family, presumably Ashkenazi immigrants from Germany or Austria, the book came into the possession of Cardinal Richelieu some time after 1632 and was stored at the Sorbonne before being moved to the Bibliothèque nationale de France, where it is currently stored as Ms. Héb 586.
