Severinus Boethius’s works in English

The following is Wikipedia’s bibliography of works by Anicius Manlius Severinus Boethius, with added links to where each of them can be found in English. As of now, all works have a link to at least one translation, either a professional one or one I generated for my Translations Blog; so the post is unlikely to be updated any more, unless new professional translations become available.

Mathematical works

• De arithmetica (On Arithmetic, c. 500) adapted translation of the Introductio Arithmeticae by Nicomachus of Gerasa (c. 160 – c. 220). – at LibGen
• De musica (On Music, c. 510), based on a lost work by Nicomachus of Gerasa and on Ptolemy’s Harmonica. – at LibGen
• Possibly a treatise on geometry, extant only in fragments.

Logical Works

His translations were into Latin, and it would be superfluous to render his Latin into English. The links go to English translations of these works from the originals.
