he offered one of the earliest definitions of "archaeologia" to describe the study of antiquities in which he was engaged. In 1681 Spon published a brief (95pp.) treatise on fevers, which, being well-received, he expanded to 264 pp. to include the latest remedies, including "Quinquina" from "Perou," which he considers especially effective, but which, he says, the "Ameriquains" did not recognize: "le quinquina n'etoit pas connu pour la guerison des fievres par les Ameriquains meme...". "Observations sur les Fievres et les Febrifuges" was published by Thomas Amaulry at Lyon in 1684 and posthumously in 1687. Spon points out that he is an expert on fevers because Lyon includes a swampy area (the Dombes) that produces "mauvais air" responsible for fevers—probably actually malaria. As Spon's book illustrates, in the 17th century a whole range of diseases were classified as different "fevers." In its time, "Observations sur les Fievres" was a learned, technical manual for a physician who wanted to be current. The Revocation of the Edict of Nantes, October 1685, was indirectly the cause of Spon's death. Rather than abjure his Calvinist faith, he preferred to leave for Zurich, an illegal move. His money and baggage were stolen from him, and in fragile health, he died of tuberculosis in the canton hospital at Vevey, Christmas Day 1685, at the age of 38.
