Many Romans were grecophiles, and it showed. Not only did many feel Latin wasn’t a suitable language for philosophy, but also for mathematics. Of course, they also distrusted Arabic numerals.
Yeah. So, in the West, Rome proper didn’t allow Hebrew numbers. However, in Constantinople, all accounting had to be done in Greek or Latin and Arabic numerals were forbidden. One can cite all kinds of reasons: tax assessors not wanting to learn it, distrust of foreigners, the fact that the Rhomaioi were almost always at war with the Arabs and/or Turks.
