However, Vologases I was still satisfied with this result and honored the memory of Nero, though he stood in good relations with Vespasian also, to whom he offered an army of 40,000 horse archers during the Jewish Revolt. Soon afterwards the Alans, a great nomadic tribe beyond the Caucasus, invaded Atropatene and Armenia; Vologases I applied in vain for help to Vespasian, but did not achieve any decisive result.
