ISAURA, or ISAURUS, in Ancient Geography, a strong city at Mount Taurus, in Isauria, twice demolished; first by Perdiccas, or rather by the inhabitants, who, through despair, destroyed themselves by fire rather than fall into the hands of the enemy; again by Servilius, who thence took the surname Isauricus. Strabo says there were two Isauras, the old and the new, but so near that other writers took them but for one.
