LIEUTAUD, Connoissance des temps pour l'année 1727

First edition.
First published in 1679, this astronomical yearbook was immediately a great success, given its usefulness, and has never suffered any interruption. First written by Abbé Jean Picard, then by his fellow academician, Le Febvre, it was, after the reform of the Royal Academy of Sciences in 1699, developed by a team of academicians: Jacques Lieutaud surrounded by Réaumur, Galon and Cassini.
