Giovanni Domenico Cassini
The appearance of the Italian astronomer Giovanni Domenico Cassini in the
picture is somewhat surprising (at least to me). He became a member of the
Académie des Sciences in 1669 and was from that moment, with a yearly salary
of 9.000 Livres, the highest paid scientist in the Académie.
Apart from Du Hamel and Huygens, Cassini is the only scientist who is
painted full length, his legs only partly obscured by a globe, whilst himself obscuring
part of the right side of Christiaan Huygens.
Most of the later portraits, like the one shown above (painted by Beaubrun/engraved by Nicolas Gabriel Dupuis, 1698-1771) , are based on Cassinis pose and clothing in this
picture: scroll in the left hand, a curtain with the Observatoire in the
