indivisibles (atoma) with the fundamental principles of mathematics. De ̄me ̄trios, not citing
E explicitly, discusses bisecting straight lines and angles (1061: col.9–11; cf. Euclid
1.prop.9–10), and the properties of circles (1061: col.8.9–17: cf. Eucl. 1.def.15).

De ̄me ̄trios of Kallatis (215 – 145 BCE)
Historian, wrote a geography About Asia and Europe in 20 books (D L 5.83),
treating Sarmatian history and topography, and referring to the death of Hiero ̄n II of
Surakousai (F3: 216 BCE). De ̄me ̄trios is cited with D as treating the world’s
northern quadrant (A K, Book 5, fr.65). His account of all
the earthquakes occurring in Greece, of which S provides a lengthy synopsis
(F6: 1.3.20) was, presumably, part of the larger history.

De ̄me ̄trios of Lako ̄nika (150 – 80 BCE)
Epicurean student of P B and younger associate of Z
S. The Herculaneum papyri contain numerous fragments of De ̄me ̄trios’ works on
poetry, physics, mathematics, theology, and philology. Some of his views can be
reconstructed from these fragments and later reports of his doctrines. He defended E-
’ views on the size of the Sun, the nature of the gods, the infinity of space, the infinite
number of atoms, inference from similarities (P, On Signs 45 – 46), the nature of
time (“an accident of accidents”), the Epicurean theory of minima, and, against
K, he defended the existence of proof. He also considered the possibility that
some apparent shortcomings in Epicurean philosophy were caused by scribal errors in
earlier MSS.

De ̄modamas of Mile ̄tos (290 – 260 BCE)
General of Seleukos and Antiokhos, crossed the Iaxartes river, and wrote an account of
those lands, which P followed: 1.ind.6, 6.49; repeated in I S 49.1–6 and
M C 6.692. S B, s.v. Antissa, notes an Indian
island of that name in “De ̄modamas the Milesian.”
