ISAURA, (anc. geog.), a strong city at mount Taurus, in Ifauria: 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 Ifauricus. Strabo says, there were two Ifaurus, the old and the new, but so near, that other writers took them but for one.
