Wergeland's "Jan van Huysums Blomsterstykke" (Flower-piece by Jan van Huysum, 1840), "Svalen" (The Swallow, also translated to English, 1841), "Jøden" (The Jew 1842), "Jødinden" (The Jewess 1844) and "Den Engelske Lods" (The English Pilot 1844), form a series of narrative poems in short lyrical metres which remain the most interesting and important of their kind in Norwegian literature. He was less successful in other branches of letters; in the drama neither his "Campbellerne" (The Campbells 1839), "Venetianerne" (The Venetians 1843), nor "Søkadetterne" (The Sea Cadets 1837), achieved any lasting success; while his elaborate contribution to political history, "Norges Constitutions Historie" (The History of the Norwegian Constitution 1841–1843, is still regarded as an important source. The poems of his later years include many lyrics of great beauty, which are among the permanent treasures of Norwegian poetry.
