The land of the Ahiank‘ or Caucasian Albania, whose geography and customs already attracted the attention of Strabo and Pliny, represents the easternmost part of the Armenian sphere of influence. The historical events which took place in this region were described by the ancient Armenian historians P'awstos Biwzandai, Lazar P'arpei, Elišē Vardapet, Movsēs Xorenai, etc., and their works were subsequently drawn upon by Movsēs Kalankatuai or Dasxuranci for the compilation called the History of the Aluank' which remains our principal source of information on the country down to the tenth century.
