The scantiness of Parthian inscribed material enhances the importance of any new find. The existence of inscriptions and drawings on the rock-walls of a gorge near Birjand (Southern Khorasan) had been known for some time; but their antiquity was not recognized until Mr. Jamal Rezai, a Persian student from Birjand, visited the gorge and took photographs, which he submitted to Dr. Sadiq Kiya, of the University of Tehran. Dr. Kiya at once correctly identified the writing as Parthian and, in company with Mr. Rezai, published the whole material, together with a preliminary reading of the inscriptions. Dr. Richard N. Frye also paid a visit to the site and reported on it briefly in the Persian literary monthly Mihr. Later some uninformed criticism, claiming modern origin of the remains, appeared in the same periodical; it was justly refuted by Dr. Kiya.
