Fortin, a globe maker for the French royal family, was commissioned to produce a revised edition of Flamsteed's star atlas, and it turned out to be a very successful enterprise. All of Flamsteed's twenty-six plates were re-engraved on a much smaller scale, so that they now measured only 23 by 18 cm. In Flamsteed's 1729 Atlas Coelestis, the original plates were 55 x 41 cm, and the plate depicting Hydra was a double-page folding plate. .
