Giovanni Domenico Cassini
He attracted the attention of members of the Academy of Sciences and in 1699 was sent by order of the king on a voyage to the Levant with Giovanni Domenico Cassini to determine the geographical positions of a number of seaports and other cities. The success of the undertaking led him to make a similar journey to the Antilles in 1703. He left Marseilles on 5 February 1703 and arrived at Martinique on 11 April.
