 Many of the antiquities collected by the French in Egypt were seized by the British Navy and ended up in the British Museum – only about 50 of the 5,000 Egyptian objects in the Louvre were collected during the 1799–1801 Egyptian expedition.Even so, the scholars' research in Egypt gave rise to the 4-volume "Mémoires sur l'Égypte" (published 1798–1801).A subsequent and more comprehensive text was "Description de l'Égypte", published on Napoleon's orders between 1809 and 1821.
