a physician of Burdigala (Bourdeaux) in the fourth century after Christ, mentioned, along with Autsonius and Eutropius, by Marcellus Empiricus (De Medicam. praef. p. 242), as being one of his fellow-citizens and immediate predecessors. He wrote a pharmaceutical work, which is noticed by Marcellus, but is not now extant. Fabricius (Bibl. Gr. vol. xiii. p. 423, ed. vet.) conjectures that in the passage referred to we should read Scribonius idstead of Siburius : but this is certainly an oversight; as 1. Scribonius is mentioned (by the name Designatianus) as a different person in a former clause of the same sentence ; 2. he lived in the first century, not in the fourth; and 3. there is no reason for believing that he was a native of Bourdeaux.
