My article written some twenty years ago had a twofold purpose: to insist on the importance of a systematic study of the toponymy of Persia and, by way of example, to examine the Mongolian stratum of placenames in the southernmost area of the Persian province of Azarbayjan.
Much of what I said in the first part of the original draft has happily become superfluous in view of the appearance of a very welcome series of volumes which, in the years 1328–32/1949–53, was published by the Persian Army Survey, under the title of Farhang-i joghrāfiyāyi-yī Irān. The production of this series is chiefly due to the enlightened endeavours of the former chief of the Survey, General Hosayn ‘Ali Razmārā (brother of the assassinated premier).
