EICEPE, called also HEICET and HEICETON, heretics of the seventh century, who made profession of the monastic life. — From that passage in Exodus, where Moses and the children of Israel are said to have sung a song in praise of the Lord, after they had passed the Red Sea, wherein their enemies had perished; the eicepe concluded, that they must sing and dance to praise God aright; and as Mary the prophetess, sister of Moses and Aaron, took a drum in her hand, on the same occasion, and all the women did the like, to testify their joy, by playing, beating, and dancing; the eicepe, the better to imitate their conduct herein, endeavoured to draw women to them to make profession of the monastic life, and assist in their mirth.
