Another fragment was discovered in Russia in 1817 and was published in German by the St. Petersburg Academy in 1823. This material includes certain passages previously published by J. L. Rasmussen in 1814. Rasmussen worked from a manuscript he found in Copenhagen, since lost, and of dubious origins. There were also Swedish, French, and English translations at this time, but they are all notoriously inaccurate and apparently do not include any new material.

In 1878, two new manuscripts were discovered in the private antiquities collection of Sir John Emerson, the British Ambassador in Constantinople. Sir John was apparently one of those avid collectors whose zeal for acquisition exceeded his interest in the particular item acquired. The manuscripts were found after his death; no one knows where he obtained them, or when.

One is a geography in Arabic by Ahmad Tusi, reliably dated at A.D. 1047. This makes the Tusi manuscript chronologically closer than any other to the original of Ibn Fadlan, which was presumably written around A.D. 924-926. Yet scholars regard the Tusi manuscript as the least trustworthy of all the sources; the text is full of obvious errors and internal inconsistencies, and although it quotes at length from one “Ibn Faqih” who visited the North country, many authorities hesitate to accept this material.

The second manuscript is that of Amin Razi, dating roughly from A.D. 1585-1595. It is written in Latin and according to its author is translated directly from the Arabic text of Ibn Fadlan. The Razi manuscript contains some material about the Oguz Turks, and several passages concerning battles with the mist monsters, not found in other sources.

In 1934, a final text in Medieval Latin was found in the monastery of Xymos, near Thessalonika in northeastern Greece. The Xymos manuscript contains further commentary on Ibn Fadlan’s relations with the Caliph, and his experiences with the creatures of the North country. The author and date of the Xymos manuscript are both uncertain.
