(Πάκκιος), or Pa'cciusAntiochus (ΠάκκιοςἈντίοχος), a physician about the beginning of the Christian era, who was a pupil of Philonides of Catana, and lived probably at Rome. He made a large fortune by the sale of a certain medicine of his own invention, which was much employed, and the composition of which he kept a profound secret. At his death he left his prescription as a legacy to the Emperor Tiberius, who, in order to give it as wide a circulation as possible, ordered a copy of it to be placed in all the public libraries. (Scribon. Larg. De Compos Medicam. 23.97. p. 209; Marcell. Empir. De Medicam. 100.20. p. 324.) Some of his medical formulae are quoted by Galen (De Compos. Medcamt. sec. Loc. 4.4, 8, 9.4, vol. xii. pp. 715, 751, 760, 772, 782, 13.284; De Compos. Medicam. sec. Gen. 7.7, vol. xiii. p. 984), Scribonius Lar (l.c., and 40.156. p. 218), Atius (2.3.109, 111, pp. 354, 359), and Marcellus Empiricus (l.c.)
