Heirs of Alexandria

A series of novels by writers Mercedes Lackey, Eric Flint, and David Freer. They are Historical Fantasy novels set in an alternate Venice in the 1530s. The point of divergence from our history (other than the addition of Functional Magic), was Hypatia being converted to Christianity and stopping the mob from destroying the Library of Alexandria, eventually splitting the Church into the Petrines, under her own and St. Peter’s doctrine, and the Paulines, under St. Augustine and Paul’s doctrine.
