A massive and justly famous compendium of Jesuit letters written from about 1706 to justify their activities in various parts of the world, and to raise funds for their mission. Volumes 1–5 concern the Levant, 6–9 America, 10–15 the Indies, and 16–26 China. The original version appeared between 1702 and 1776. Querbeuf rearranged the letters on a more systematic basis and his edition, which first appeared in 1780–83, is often preferred to the original for its better organisation.
