An engraving of the Paris Observatory from the beginning of the eighteenth century shows the wooden "Marly tower" on the right, a dismantled part of the Machine de Marly (the temporary tower replaced by La tour du Levant at the beginning of the Aqueduc de Louveciennes), moved to the Paris Observatory by astronomer Giovanni Domenico Cassini for mounting long telescopes.
