to Thumaridas his “Bloom” (epanthe ̄ma), which formulates in complex prose the idea that if
x + y 1 +... + yn− 1 = a and x + yi = bi, then:
x=b 1 +...+bn− 1 −a
n− 2.
Iamblikhos then demonstrates how other equations can be reduced to it. In most recent
accounts, Thumaridas is assigned to Paros, and said to be P’ contemporary or per-
haps even earlier. But what is said about Thumaridas in the Life of Pythagoras is legendary
tradition rather than history, and some scholars assign the mathematical ideas associated
with him in the commentary on Nikomakhos to the common era.

Tiberianus (ca 300 – 330 CE)
Possibly a prefect of Rome in 303–304, wrote poems, including a prayer to the Platonic
Demiurge (carmen 4), following Platonic doctrines and influencing B (Consolatio
3, carmen 9.22). Tiberianus prays for knowledge to a divinity who is unique and many in
itself, a cause of the world. But he equates it with the whole nature and considers this world
a home of both men and gods, reflecting Stoic views.

Tiberius (ca 150 CE – ca 500 CE?)
Wrote on the medical treatment of horses and cows. Tiberius’ name belongs to late
antiquity; however, there is no evidence in his text for a precise date. Excerpts are preserved
in the 10th c. B recension, the L recension, and the RV recension of the Hippiatrika. Tiberius
is related to the agricultural writers: his text contains parallels with V A
and I A. No treatments for cows appear in B, but a list of them is appended
to L, and some appear anonymously in RV.

Timagene ̄s of Alexandria (ca 75 – ca 25 BCE)
Greek historian and rhetorician, apparently impulsive, witty and sharp, son of a royal mon-
eychanger. Timagene ̄s arrived in Rome in 55 BCE as A. Gabinius’ prisoner. Sulla’s son
Faustus liberated him. Seneca reports that “from captive he became a cook, from cook a
chair-carrier, from chair-carrier a friend of A” (Sen. Sr., Contr. 10.5.22). A,
angry over Timagene ̄s’ remarks about the emperor and his family, banished Timagene ̄s
from his house; in response Timagene ̄s burned parts of his histories relating to the
