A collection of Galilean satellite eclipses 1652-1982

Data from visual observations of the eclipses of the Jovian Galilean satellites recorded in two 17th and 18th century manuscripts are analyzed. It is shown that a 'lost' group of more than 6800 eclipse observations known as the Delambre collection is actually contained in two smaller manuscripts, the Pingre book and the Delisle manuscript. The data in the collections are expected to be useful in determining the ephemerides, masses and libration parameters of the Jovian satellites, for the study of questions related to Delta T (Ephemeris Time-Universal Time) as it was recorded in the 17th century, and for the study of the Laplace commensurability.
