HERON, called the younger, to distinguish him from his namesake of Alexandria, was, like him, a mathematician and natural philosopher. His birthplace, or even his country, is quite unknown, and even his floruit is only guessed to have been contemporaneous with that of the Emperor
Heraclius, A.D. 610-641. The writings assigned to this Heron are a treatise on Geodasia, or practical geometry; another on the Terms of Geometry; and some works on various military matters, such as The Attack and Defence of Towns; the Machines of War. Some of these works appear in the Mathematici Veteres; others are printed separately; and some are still in MS.
