IOTIMUS: Evidently an associate of HADRIAN (2), not otherwise known. (8.25,
8.37)
OMITIUS: Unidentified, perhaps a student of ATHENODOTUS. (1.13)MPEDOCLES: Fifth-century B.C. Greek philosopher and poet who regarded the
natural world as the result of constant mingling and separating of four basic
elements. (quoted 8.41, 12.3)
PICTETUS: Stoic philosopher (c. 55–c. 135), a former slave from Phrygia who
was among the most influential figures in later Stoicism. A record of his
lectures and discussions (the Discourses) was published by his student
Arrian, along with an abridged version (the Encheiridion, or “Handbook”).

PICURUS: Greek philosopher (341–270 B.C.) and founder of one of the two
great Hellenistic philosophical systems. Epicureans identified pleasure as the

PITYNCHANUS: Perhaps a slave or freedman of HADRIAN (2). (8.25)
UDAEMON: Perhaps to be identified with a literary official prominent under
Hadrian (2). (8.25)
UDOXUS: Greek mathematician and astronomer active in the fourth century
B.C. (6.47)
UPHRATES: Perhaps the philosopher mentioned by Pliny the Younger (Letters
1.10) and evidently close to HADRIAN (2), but he might be a later imperial
official mentioned by Galen. (10.31)
URIPIDES: Athenian playwright (480s–407/6 B.C.); some twenty of his
tragedies are still extant. His plays were controversial in his lifetime, but in
subsequent centuries he was among the most popular of Greek authors,
