Brand is the author of one of the two eyewitness accounts existing on Eberhard Isbrand Ides' journey to China (the other one was written by Ides himself). His report, written in German, to which was added an opuscule by H. W. Ludolff entitled "Curieuse Beschreibung der natürlichen Dingen Rußlands" (Curious observations concerning the products of Russia), was first published in the year 1698 in
Hamburg. This report became extremely popular in Western Europe. Brand sent an extract from his manuscript to
Leibniz who translated it into Latin and inserted it in his work Novissima Sinica (1697). ==List of works==
