Excerpt: Philo of Byzantium (Greek: ), also known as Philo Mechanicus, was a Greek engineer and writer on mechanics, lived during the latter half of the 3nd century BCE. He was probably younger than Ctesibius, though some place him a century earlier. Philo was the author of a large work, Mechanike syntaxis (Compendium of Mechanics), which contained the following sections: The military sections Belopoeica and Poliorcetica are extant in Greek, detailing missiles, the construction of fortresses, provisioning, attack and defence, as are fragments of Isagoge and Automatopoeica (ed.

Further portions probably survive in a derivative form, incorporated into the works of Vitruvius and of Arabic authors.
