probably the main source of Pliny and later encyclopedists for natural history in exotic
countries. His work was lost and unknown to Latin early medieval writers, but “Iorach,”
often quoted as a scientific authority in Arabic literature and influential on medieval
encyclopedias (e.g. Arnoldus Saxo), is very probably Iouba II himself.

Ioudaios (250 BCE – 25 CE)
Physician whose plaster for skull fractures consisted in salt, red copper scales, roasted
copper, ammo ̄niakon incense, frankincense soot, dried resin, “Kolopho ̄n” resin, calf
suet, vinegar and olive oil (C 5.19.11B). Celsus also preserves Ioudaios’ skin pow-
der of lime, red natron, and a young boy’s urine, recommending that the area to be
treated be moistened occasionally (5.22.4). Ioudaios, attested only once, 2nd c. BCE
(LGPN 3B.207), is perhaps a corruption of the ethnic Ioudas, Ioudion, or Ioudio ̄n known
from the 1st c. CE (LGPN).

Irio ̄n (?) (250 BCE – 80 CE)
A, in G CMGen 6.10 (13.913 K.), records this man’s phaia (dark) plaster,
containing litharge, roast copper, and verdigris, plus birthwort, galbanum, and opop-
anax, in a beeswax-and-resin base. The name ΙPIΩΝ seems otherwise unattested, and
perhaps we ought to read ΕΙΡΗΝΙΩΝ (LGPN 2.139) or else (HPIΩΝ (LGPN 3B.183–184).
Alternatively, it may be a brand-name, as are the immediately preceding (“Phtheirograph”)
and following (“Hellespontian”) plasters.

Isido ̄ros (300 – 500 CE?)
Found in the list of philosophers “of the science and of the sacred art,” at the beginning of
MS Marcianus gr. 299 (f.7V), and probably identifiable with P, an Egyptian synonym
of “Isido ̄ros” (gift of Isis).
