Suidas, who mentions several works besides, speaks of one entitled μέτρων Πεδισμοί, which is believed to be the same as the Ἐγχειρίδιον περὶ μέτρων, which has come down to us under the name of Hephaestion, and is a tolerably complete manual of Greek metres, forming, in fact, the basis of all our knowledge on that subject. This little work is of great value, not only on account of the information it affords us on the subject it treats of, but also on account of the numerous quotations it contains from other writers, especially poets.
William Smith. A Dictionary of Greek and Roman biography and mythology. London. John Murray: printed by Spottiswoode and Co., New-Street Square and Parliament Street. In the article on Soranus, we find: "at this present time (1848)" and this date seems to reflect the dates of works cited. 1873 - probably the printing date.
