Reading edition
Tauris, Tabriz; Tongan, which the French editor calls “Djagorgan” (?), is probably Daumghan in Persia, south of Astrabad, mentioned by Marco Polo (ii. 17), with an allusion to the Christians there; and Marogo is Maragha in the plain east of Lake Urumia, formerly the capital of the Tartar Hulaku.
