Anicius Manlius Severinus Boëthius,.}} commonly called Boethius. It is hence traditionally written with a diæresis, viz. "Boëthius", a spelling which has been disappearing due to the limitations of typewriters.}} (; also Boetius ; 477–524 AD), was a Roman senator, consul, ''magister officiorum'', and philosopher of the early 6th century. He was born about a year after Odoacer deposed the last Western Roman Emperor and declared himself King of Italy.
Boethius entered public service under Ostrogothic King Theodoric the Great, who later imprisoned and executed him in 524 on charges of conspiracy to overthrow him.
While jailed, Boethius composed his ''Consolation of Philosophy'', a philosophical treatise on fortune, death, and other issues, which became one of the most popular and influential works of the Middle Ages. As the author of numerous handbooks and translator of Aristotle, he became the main intermediary between Classical antiquity and following centuries.
