Cométographie ou traité historique et théorique des comètes.

Paris, Imprimerie Royale, 1783-84. ____ Première édition. Histoire des théories sur les comètes et catalogue de toutes celles qui ont été observées dans l'histoire. Pingré fait une large place à l'astronomie chinoise. Il a étudié un manuscrit du père jésuite Gaubil, astronome qui résida en Chine de 1723 à 1759. Ce travail monumental est toujours précieux pour les données historiques relatives aux passages des comètes. Illustré par 7 planches hors-texte. Bel exemplaire, frais. *-------* First edition. History of comets theories and catalog of all those that have been observed in history. Pingré most important work. "This monumental work was divided into four parts, the first of which was a history of astronomy from Babylonian and Egyptian times, with particular reference to ideas about comets. The second part was a catalog of all comets observed since antiquity, with the orbital elements of 166 for which paths had been computed, 50 of them by Pingré himself. The third section discussed cometary returns, theories about the nature of comets, and the physical effects likely to ensue from their close approach to the earth. The fourth part concerned cometary orbits and methods for computing them. The high reputation of the Cométographie was deserved, and as recently as 1950 it was officially recommended as a source book of cometary information." D.S.B. X, 615. ______ Format : 2 volumes in-4.
