A number of travelers who came to the Levant (later also to India) explicitly for scientific research, using the merchant network as a starting point for their inland excursions to study flora, fauna, and monuments, left traces of their travel libraries between 1700 and 1750: Tourtechot de Granger, Hebenstreit, and Ludwig, and the curious case of the first French Linnaean “apostle,” Simon de Verville, who converted to Islam in Aleppo. Granger’s and Verville’s libraries represent a continuity in the development of French academic science after Tournefort, in competition with and emulation of Linnaeus, which also integrated elements of early Freemasonry. Simon de Verville was in close contact with the British in Aleppo, who themselves welcomed natural historians such as the Russell brothers, exponents of the Scottish Enlightenment, but no catalogs of the libraries at their disposal in Aleppo have survived. The German Leipzig travelers, who mostly used the Protestant British consular and factory network, are a curious exception, as elements of deductive Wolffianism are in disharmony with the empirical purpose of their study. For India, although there are several rich studies of botanical and other explorations—at least for the British—that fed centers of calculation such as the apothecary-botanist James Petiver in London alongside the circles of the Royal Society led by Hans Sloane and his successors, no record of a deceased scientific traveler and his travel library has been found in the sources before 1750.
