Boethius played a pivotal role in preserving arithmetic knowledge in medieval Europe by creating Latin redactions of Greek scientific writings during a period when knowledge of the Greek language had largely faded in the West.1

His most significant contribution was his Arithmetic, which was based on the work of the 1st-century mathematician Nicomachus of Gerasa. This text served as the primary means by which medieval scholars gained access to Pythagorean number theory.12

Furthermore, Boethius, alongside Cassiodorus, provided the essential educational material for the quadrivium—a foundational curriculum consisting of arithmetic, geometry, astronomy, and music theory. These subjects, combined with the trivium, formed the liberal arts that were taught in monasteries, cathedral schools, and eventually universities, ensuring that these classical mathematical foundations remained a core component of Western education for centuries.1
