Passow's great work was his Handwörterbuch der griechischen Sprache (1819–1824) ("Dictionary of the Greek Language"), originally a revision of Johann Gottlob Schneider's lexicon, which appeared in the fourth edition (1831) as an independent work, without Schneider's name. Other works by Passow are Grundzüge der griech. und röm. Literatur und Kunstgeschichte (“Foundations of Greek and Roman Literature and History of Art”; 2nd ed., 1829) and editions of Persius, Longus, Tacitus's Germania, Dionysius Periegetes, and Musaeus. His miscellaneous writings were collected in Opuscula academica (“Minor academic works”; 1835) and Vermischte Schriften (“Miscellaneous writings”; 1843).
