The marble Jason was not finished until 25 years later, as Thorvaldsen quickly became a busy man. Also in 1803, he started work on "Achilles and Briseïs" his first classically themed relief. In 1804 he finished "Dance of the Muses at Helicon" and a group statue of "Cupid and Psyche" and other important early works such as "Apollo, Bacchus og Ganymedes". During 1805, he had to expand his workshop and enlist the help of several assistants. These assistants undertook most of the marble cutting, and the master limited himself to doing the sketches and finishing touches. Commissioned by Ludwig I of Bavaria in 1808 and finished in 1832 a statue of "Adonis" is one of the few works in marble carved solely by Thorvaldsen's own hand, and at the same time it is one of the works that is closest to the antique Greek ideals.
