The original text of Hornemann's journal, which was written in German, was printed at Weimar in 1801; an English translation, The Journal of Frederick Hornemann's travels, from Cairo to Mourzouk : the Capital of the Kingdom of Fezzan, in Africa, with maps and dissertations by Major James Rennell, appeared in London in 1802. A French translation of the English work, made by order of the First Consuls and augmented with notes and a memoir on the Egyptian oases by L. Langlès, was published in Paris in the following year. The French version is the most valuable of the three.
