Final answer:
The definitive canon of the Greek/Catholic Old Testament was established in 1442 by the Western Church. St. Jerome's Vulgate, translated in 410, was the standard edition of the Bible in Latin until the 16th century. The 1453 fall of the Byzantine Empire led to an influx of Greek scholars that may have influenced biblical scholarship.
Step-by-step explanation:
The canon of the Greek/Catholic Old Testament was a process that took centuries to stabilize, with regional variances and debates over certain books. It wasn't until 1442 that the Church in the West definitively established the canon of books to be included in the Old Testament during the Renaissance.
This followed translations of the bible like the Vulgate, penned by St. Jerome in 410, which became the standard Latin translation widely used in Europe up until the sixteenth century. After the fall of the Byzantine Empire in 1453, there was an influx of Greek scholars in the West, which contributed to a resurgence in interest in classical texts and could have influenced religious and scholarly work on the Bible.
