(Γαβριήλιος), prefect of Byzantium, under the emperor Justinian. The Greek Anthology contains an inscription for his statue, by Leontius (Brunck, Anal vol. iii, p. 103 ; Jacobs, Anth. Graec. vol. iv. p. 74), and one epigram by Gabriel himself. (Brunck, Anal. vol. iii. p. 7; Jacobs, Anth. Graec. vol. iii. p. 228.) The astrological writer, Johannes Laurentius Lydus, inscribed three of his books to Gabriel. There are several ecclesiastical writers of this name, but they are of no importance. (Fabric. Bibl. Graec. vol. iv. pp. 156, 475; Jacobs, Anth. Graec. vol. xiii. pp. 895-6.)
