[887] The work of Martin, Recherches sur la vie et les ouvrages d’Héron d’Alexandrie, Paris, 1854, and the accounts of Hero in histories of physics and mathematics such as those of Heller and Cajori, must now be supplemented by the long article in Pauly and Wissowa, Realencyclopädie der classischen Altertumswissenschaft, (1912), cols. 992-1080. A recent briefer summary in English is the article by T. L. Heath, EB, 11th edition, XIII, 378. See also Hammer-Jensen, Ptolemaios und Heron, in Hermes, XLVIII (1913), p. 224, et seq.
The writings ascribed to Hero, hitherto scattered about in various for the most part inaccessible editions and MSS, are now appearing in a single Teubner edition, of which five vols. have appeared, 1899, 1900, 1903, 1912, 1914, including respectively, the Pneumatics and Automatic Theater, the Mechanics and Mirrors, the Metrics and Dioptra, the Definitions and geometrical remains, Stereometrica and De mensuris and De geodaesia. For the Belopoiika or work on military engines see C. Wescher, Poliorcétique des Grecs, Paris, 1867. In English we have The Pneumatics of Hero of Alexandria, translated for Bennet Woodcroft by J. G. Greenwood, London, 1851. A number of articles on Hero by Heiberg, Carra de Vaux, Schmidt, and others will be found in Bibliotheca Mathematica and Sudhoff’s Archiv f. d. Gesch. d. Naturwiss. u. d. Technik.
