The Consolation of Philosophy and The Theological Tractates

The original Latin text plus an English translation of both books. According to Wikipedia: "Anicius Manlius Severinus Boëthius (ca. 480–524 or 525) was a Christian or pagan philosopher of the 6th century. He was born in Rome to an ancient and important family which included emperors Petronius Maximus and Olybrius and many consuls. His father, Flavius Manlius Boethius, was consul in 487 after Odoacer deposed the last Western Roman Emperor. Boethius himself was consul in 510 in the kingdom of the Ostrogoths. In 522 he saw his two sons become consuls. Boethius was executed by King Theodoric the Great, who suspected him of conspiring with the Byzantine Empire."
