Ulpianus (ca 475 – 500 CE)
Brother of the late Neo-Platonist Isido ̄ros of Alexandria (Souda O-914 [Oulpianos], deriv-
ing partly from D’ Vita Isidori). His natural talent for solving mathematical
problems, noted in particular by Syrianus the younger (= Syrianus 4 in PLRE 2 [1980]
1051 – 1052; RE 4A.2 [1932] 1775 [#2], K. Praechter), made him famous at Athens;
by contrast, he produced no philosophical arguments of any worth (a commonplace in
Damaskios), nor are any titles attributed to him. He died young and never married.
PLRE 2 (1980) 1181.

Ulpianus of Emesa (ca 300 – 330 CE)
Sophist, born in Askalon, taught rhetoric at Emesa and at Antioch, to L, Proair-
e ̄sios and Makedonios; his successor in the post was Ze ̄nobios. His own rhetorical works and
declamations (Souda O-911) are lost. The suggested authorship of the scholia to 18 speeches
of De ̄mosthene ̄s, with some geographical material, is doubtful (FGrHist 676).
RE 9A.1 (1961) 569 (#3), A. Lippold; KP 5 (1975) 1044 (#2), H.A. Gärtner; OCD3 1570, N.G. Wilson.

Urbicius (ca 490 – ca 520 CE)
Author of Epite ̄deuma (Invention), addressed to Anastasios, as well as Tactica, and perhaps an
extant Kune ̄getika. The Invention describes two innovations (cf. D R B): bundles
of spiked poles for rapid construction of an anti-cavalry fence (§ 4 – 7), and ballistae mounted
upon carts as mobile artillery (§8, 14–16; already attested on Trajan’s column).

Commentary,” ByzZ 98 (2005) 35–74.
