A Manuscript in the library of St. Mark at Venice contains a citation, printed by Villoison, from a Greek treatise on versification by " Helias, a monk of Charax." Villoison states that the passage cited by him is, in several MSS. of the King's Library at Paris, improperly ascribed to Plutarch. Harless incorrectly represents Villoison as speaking of two works of Helias on versification, and without, or rather against authority, connects the name of Elias of Crete with them.
