Alexander

The Macedonian, namely, who was set over those in charge of the royal equipage, Proxenus by name, as he was digging a place for the king’s tent along the river Oxus, uncovered a spring of liquid which was oily and fatty; but when the top of it was drawn off, there flowed at once a pure and clear oil, which appeared to differ from olive oil neither in odour nor in flavour, and in smoothness and lustre was altogether the same, and that too though the country produced no olive trees.
