Photius' Bibliotheca contains a book review of Nicomachus' Theology of Arithmetic, which yields a rare insight into the original text which has now been lost. The work is brief and will include both the Greek text and original English translation.

Both Iamblichus and John Philoponus left commentaries on Nicomachus' Arithmetic which have not been translated into English.

This project will provide Greek-English texts for both works with commentary.

This 11th century Byzantine Quadrivium purported to be authored by Michael Psellus has never been translated into English. This text includes sections devoted to Arithmetic, Geometry, Music, and Astronomy with copious references to the classic authors, especially Nicomachus, Euclid, and Ptolemy.

This project will provide a dual Greek-English text for the work with footnotes for references to ancient quadrivium authors.

The rules of Rithmomachia were never set before the game declined in popularity. As a result, there are several rulebooks containing variations of the game rules. Recent scholarship has provided the original Latin & vernacular texts which will now be translated into English.
