[This name is found in various forms—Mas'údí (p. 23) calls it Al Rúr; Ibn Khurdádba writes Al Daur (p. 14); Istakhrí has Al Rúz (p. 27), and Al Rúr (p. 28). The Ashkalu-l Bilád has Aldúr (p. 34), and Alrúr (p. 37); Gildemeister makes Ibn Haukal's version to be Rúz and Alrúz; Bírúní's spelling is ambiguous (see p. 48); Idrísí has Dúr (p. 79). The Marásidu-l Ittilá' has Al Rúr.] The ruins of the town lie between Bhakkar and Khairpur, and are known by the name of Alor. Lieut. Maclagan says that it is also called Aror and that the band spoken of by Burnes is really an arched bridge. [There can be little doubt of the first syllable being the Arabic al, and the real name Rúr, as it survives in the modern town of Rorí, which stands close by the ruins of Alor.]
