The Life of Saint Sabas written by his contemporary Cyril of Scythopolis is oft referred to, but is not yet translated in full into English. Here you can see the opening pages of the life in Greek.
Saint Sabas’s monastery in the Holy Land (today in the territory of the Palestinian Authority) is one of the oldest continually occupied in the world. Learn more about it at WysInfo Docuwebs.
Perhaps a little tangential, but a fun tangent, you can read an archaeologist writing about “The Visits of St. Sabas to Beth Shean.” Beth Shean is the Israeli name for Scythopolis, the hometown of Sabas’s biographer Cyril.
San Saba in Rome
The church of the monastery of San Saba in Rome was founded in the seventh century by monks from Mar Saba fleeing invaders from the east. Enjoy this photo album. You can read more about the church at the excellent Churches of Rome Wiki (now hosted by Fandom).
