Arnold Böcklin (both: är´nôlt bök´lēn), 1827–1901, Swiss painter. Most of his life was spent in Italy. With Feuerbach he led the group of painters known as "German Romans," who attempted to express an idealistic philosophy through art. His carefully constructed works are largely classical in theme and often theatrical in sentiment. Among his paintings are Island of the Dead (Metropolitan Mus.) and mythological frescoes (Basel).
