“… the place which is known by the name of Geskleithron, the Arimaspi are said to exist .

forehead. This race is said to carry on a perpetual warfare with the Griffins, a kind of
monster, with wings, as they are commonly represented, for the gold which they dig out
of the mines, and which these wild beasts retain and keep watch over with a singular
degree of cupidity, while the Arimaspi are equally desirous to get possession of it.”

3. Herbal Medicine: De Materia Medica
• Dioscorides (40 – 90)
• 500 plants with medicinal uses
Acorum has leaves which resemble those of iris very
much only narrower, and the roots are similar only
one wrapped in the other, not growing downward but
sidelong in the upper part of the earth. They are sharp to
the taste, distinguished by pale white knots, and not
unpleasant to smell. The best is thick and white, not
worm-eaten, full and fragrant. Root such as this comes
from Colchis and from Galatia and is called asplenium.
The root is heating and a decoction of it (taken as a
drink) causes an urge to urinate. It is good for pain of the
rectum, chest and liver; and for griping, hernia and
convulsions. It reduces the spleen, and it helps those sick
with dripping mucus, and those poisoned by animal
bites. It is effective in a hip bath like iris for female
problems. The juice of the root cleans off things that
darken the pupils of the eyes. The root of it is also
effective mixed with antidotes. It is also called chorus,
aphrodisia or the mariner’s root; the Romans call it venerea,
and the Gauls call it the pepper of bees, piper apum.
