ALYPIUS, a Greek writer on music whose works, with those of six others, were collected and published with a commentary and explanatory notes (Antiquae Musicae Auctores Septem, Amstel., 1652), by Mark Meibomius (1630-1711). He is said to have written before Euclid and Ptolemy; and Cassiodorus arranges his Introduction to Music between those of Nicomachus and Gau dentius. The work consists solely of a list of symbols of the various scales and modes, and is probably only a fragment.
