Note 11 — Chapter XLVI

[Onan Kerule is “the country watered by the Orkhon and Kerulun Rivers, i.e. the country to the south and south-east of Lake Baikal. The headquarters (ya-chang) of the principal chief of the Uigurs in the eighth century was 500 li (about 165 miles) south-west of the confluence of the Wen-Kun ho (Orkhon) and the Tu-lo ho (Tura). Its ruins, sometimes, but wrongly, confounded with those of the Mongol city of Karakorum, some 20 miles from it, built in 1235 by Ogodai, are now known by the name of Kara Balgasun, ‘Black City.’” [See p. 228.] The name Onankerule seems to be taken from the form Onan-ou-Keloran, which occurs in Mohammedan writers. (Quatremère, 115 et seq.; see also T’ang shu, Bk. 43b; Rockhill, Rubruck, 116, note.)—H. C.]
