A distinctive feature of the period, compared to earlier European painting, was the limited number of religious paintings. Dutch Calvinism forbade religious paintings in churches, and though biblical subjects were acceptable in private homes, relatively few were produced. The other traditional classes of history and portrait painting were present, but the period is more notable for a huge variety of other genres, sub-divided into numerous specialized categories, such as scenes of peasant life, landscapes, townscapes, landscapes with animals, maritime paintings, flower paintings and still lifes of various types. The development of many of these types of painting was decisively influenced by 17th-century Dutch artists.
