“ He was a devoted friend of Napoleon, whom he accompanied in his expeditions to Austria, Spain and Poland, taking sketches with his wonted fearlessness on the various battlefields, and advising the conqueror in his choice of spoils of art from the various cities pillaged. ”

“ Here he met Bonaparte, to whose fortunes he wisely attached himself. At Bonaparte’s invitation he joined the expedition to Egypt, and thus found the opportunity of gathering the materials for his most important literary and artistic work. He accompanied General Desaix to Upper Egypt, and made numerous sketches of the monuments of ancient art, sometimes under the very fire of the enemy. The results were published in his Voyage dans la basse et la haute Égypte (2 vols, fol., with 141 plates, Paris, 1802) , a work which crowned his reputation both as an archaeologist and as an artist. ”

“ He made a portrait of the philosopher, which was engraved and published on his return to Paris. His next diplomatic appointment was to Naples, where he spent seven years, first as secretary to the embassy and afterwards as chargé d’affaires. He devoted this period to a careful study of the monuments of ancient art, collecting many specimens and making drawings of others. ”
