As a writer of books of travel he holds a high position, his powers of observation being keen and his style lucid, animated and witty. This is most evident in his first work "Briefe eines Verstorbenen" (4 vols, 1830–1831), in which he expresses many independent judgments about England and other countries he visited in the late 1820s and about prominent people he met. Among his later books of travel are "Semilassos vorletzter Weltgang" (3 vols, 1835), "Semilasso in Afrika" (5 vols, 1836), "Aus Mehemed Ali's Reich" (3 vols, 1844) and "Die Rückkehr" (3 vols, 1846–1848). "Andeutungen über Landschaftsgärtnerei" (1834, "Remarks on Landscape Gardening") was the only book he published under his own name and was widely influential.
