950s), also called Leo the Archpriest (Italian: Leone Arciprete), was a diplomat and translator in the service of Dukes John III and Marinus II of Naples.
He undertook a diplomatic mission to Constantinople, the capital of the Byzantine Empire, during the joint reign of Constantine VII and Romanus II between 945 and 959.
After Theodora's death, John commissioned Leo to translate the Romance into Latin.
[1] Leo entitled his work Nativitas et victoria Alexandri Magni regis (The Birth and Victories of Alexander the Great).
Collectively, all the derivative versions of Leo's text are known today by the title Historia de preliis (History of Battles), which was given to a pre-1500 printing of the third recension at Strasbourg.
