In the arts, the landscape painters of the Dutch and Flemish Golden Age painted a number of exquisite winter scenes, the most famous being those by Pieter Bruegel the Elder, like Winter Landscape with a Bird Trap and Hunters in the Snow (both in 1565).

Below is Aert van der Neer's Winter Landscape with Skaters on a Frozen River (1640s) in Hallwyl Museum, Stockholm. He was Amsterdam-based and he lived and died in obscurity and poverty.
Below is Lucas van Uden's Winter Landscape with Hunters (1640s), which is in a private collection. He was Antwerp-based.
