Iulianus of Askalon (ca 530 – 535 CE)
Architect from Askalon, known exclusively as author of a treatise composed around 531– 533
CE. On the laws or customs [nomoi... ethe ̄] of Palestine was transmitted as an appendix in the
Book of the Eparch (9th/10th c.) and incorporated in Harmeno ̄poulos’ Hexabiblos (14th c.).
The treatise prescribes codes for building in Askalon and encapsulates local customs as well
as the influence of Beirut’s law school. Iulianos, revealing his interests in natural philosophy,
organizes the work around the four elements of fire, air, water, and earth.
Scholars have inconclusively attempted to link him with other architects by the same
name. A Iulianos arkhitekto ̄n who built a noria is addressed in a letter by A G
(PLRE 2 [1980] 639 #16), and another Iulianos supervised repairs in an aqueduct at Sardica
(PLRE 3 [1992] 738 #21). Inscriptions referring to a Iulianos at Qasr al-Brad, Syria, have
also been associated with Iulianos of Askalon or his hypothetically homonymous father.

Kostis Kourelis
Iulianus of Laodikeia (ca 500 CE?)
Astrological author mentioned often in late antique and Byzantine Greek astrological litera-
ture. A chapter transmitted as part of the compilations of astrological texts associated with
R, in fact a reworking of the text on influences of fixed stars by the A
379, identifies “Iulianus the polyhistor” as its source, and since the positions of the stars
cited in this version have been corrected to fit a date within a year or two of 360 years after
P’s star catalogue in the Almagest (whose epoch is 137 CE), it is plausibly supposed
that Iulianus was active about 500 CE. Another section of the Rhe ̄torian corpus comprises
a series of ten chapters headed “Useful Selections from the Discoveries of Iulianus of
Laodikeia on katarkhai.” Other texts, both astrological and astronomical, came to be
falsely ascribed to him (in particular in the form of a pseudo-treatise called Astronomical
Episkepsis) through the chaotic processes by which the astrological literature was selected and
reordered in the Byzantine manuscript tradition.

Alexander Jones
Iulianus of Tralleis (100 – 180 CE?)
S, in De Caelo 2.1 (CAG 7 [1894] 379–380), quotes A A
refuting Iulianus’ theory that the cause of the regularity and right-handedness of the
motion of the heavens is “soul.” He is presumably distinct from the theourgos of ca 160 – 180
CE, who placed the Sun midmost of the planets (P, In rem Publ. 2, p. 220 = In Tim. 1,
pp. 63, 132) – always called “theourgos” and never assigned to Tralleis: BNP 6 (2005) 1045
