I want to know the answer to the following question:
Until 342 when did the Church of Rome think the vernal equinox fell?
All the background I'm provided with is that "The Church of Alexandria celebrated Easter on the Sunday after the 14th day of the moon (computed using the Metonic cycle) that falls on or after the vernal equinox, which they placed on 21 March.". Is that enough to answer the question?
