In *Alexandria (1) and Constantinople. He wrote an extant medical encyclopaedia, called the Tetrabiblon from its division into four sections. Beginning with a summary of drug theory (see pharmacology), which simplifies many obscurities in *Galen and *Oribasius, the Tetrabiblon compacts pharmacy, *dietetics, general therapeutics, hygiene, bloodletting, cathartics, prognostics, *pathology, fevers, urines, cranial ailments, eye problems (see ophthalmology), *cosmetics, and *dentistry (bks. 1–8). Unavailable are well edited editions of bks. 9–16, containing important accounts of toxicology (bk. 13), and *gynaecology and obstetrics (bk. 16; see childbirth).
