1. A physician who is mentioned by Archigenes (ap. Gal. De Compos. Medicam. see. Loc. 3.1. vol. xii. p. 623), and in terms which seem to imply that he was dead when Archigenes wrote. The name occurs several times in Aetius, who has preserved some rather large extracts from the writings of Severus. These may possibly belong to the other Severus; but upon the whole it seems better to attribute them to this one, and to suppose that those passages where mention is made of Archigenes (3.1. 34, pp. 480, 481), Oribasius (2.3. 102, 3.1. 34. pp. 348, 481), and Severus (2.3. 43, 98, 102, pp. 319, 341, 342, 347), were written by Aetius himself. If the places where Antonius Musa (2.3. 30. p. 312), Apollonius (ibid. and 2.3. 43, p. 319), and Asclepiades Pharmacion (2.3. 85, p. 334), are quoted, belong to Severus, he must have lived towards the end of the first century after Christ. One of his medical formulae is quoted by Alexander Trallianus (2.5, p. 174.). Fabricius mentions (Bibl. Gr. vol. xiii. p. 394, ed. vet.) a physician named Severianus, as quoted by Aetius ; but this is probably a mistake either in the Greek text or in the Latin translation. He also mentions a physician named Theodosius Severus ; but "Theodotium" is only the title given by Severus to one of his medicines. (See Bibl. Gr. vol. vii. p. 329.)
