^V. MINORSKY. Studies in Caucasian history. 1953. "The building of a bridge on the Araxes in 421/1030 is a hint at the extent of Fadl's dominions in the south. The bridge was a symbol either of his solicitude for the development of trade, or more probably of his designs against Azarbayjan. As explained in note 8 (to the text), I take it as more probable that Fadl's bridge was that of Khudafarm which connects the central portions of the two mountainous tracts: to the north of the Araxes, the present-day Soviet Qara-bagh; and to the south of this river, the Persian Qaraja-dagh. According to the Nuzhat al-Qulub, p. 84, one of the districts of Qaraja-dagh bore the name *Gildn-i Fadlun and consisted of so villages. This suggests that Fadl had expanded to the southern bank of the Araxes. From this region he could threaten the Rawwadis whose central axis was on the line Ahar-Tabriz. It is likely that Fadl was attracted by the eastern Azarbayjan, then lying masterless. An ode of Qatran in Kasravi, II, 93, indicates that the Rawwadis also had ambitions in the direction of Mughan. For all these reasons a bridge on the Araxes (at Khudafarin?) was a useful convenience for Fadl. "
