[1] Forster conjectures that the original words of Rubruquis are here corrupted, and that this passage ought to have been "beyond Tangut," instead of beyond Tebet or Thibet; in which case, the countries of Langa and Solanga, may refer to that of the Lamuts and Solonians, the ancestors of the Mantschus or Mundschurians.--Voy. and Disc. 108. [2] In this supposition Rubruquis was certainly mistaken, as the Seres of the ancients appear to have lived in Turkestan, Gete, and Uigur, and to have then ruled over a great track of eastern central Asia, and may have extended their commerce to northern China. Hence the original name of silk was certainly either adopted from or applied to the intermediate nation, through whom that precious commodity was transmitted to the western nations.--Forst. [3] A jascot is described as a piece of silver weighing ten marks, so that the tribute is 15,000 marks daily, or about 5 1/2 millions of marks yearly, and is equal in weight of silver, to L. 8,650,000 Sterling; perhaps equal, in real efficacious value, to ten times that sum, and probably superior to the yearly revenue of all the sovereigns then in Europe.--E [4] Singan, or Singan-fu in the province of Shensee. In the year 1625, a stone was found here, inscribed with Chinese characters and a Syrian inscription round the borders, implying, that in the year 636, the Nestorians had sent Olopuen into China to propagate the gospel; and that the emperor Tai-sum-ven had approved this step, and allowed the Christian religion to be propagated through all China, with many other particulars relative to the history of Christianity in China. This stone bore to have been erected in 782 by Mar Isdabuzzid, priest, and Chorepiscopus of Cumdan, the royal city of the east, now Nankin. See a dissertation on this monument, following Renaudet's translation of the two Mahometan travellers, London, 1788, p. 76.--E. [5] Mani or Manes is named Thenaoui by the oriental Christians, and the sect of Manicheans they call Al-Thenaouib, or those who hold the doctrines of the two principles. These Tuinians, therefore, of Rubruquis, are probably the Manicheans.--Forst. SECTION XXIX. _Of Cailac, and the Country of the Naymans_.
