The “Winter” cycle is one of Čiurlionis' most masterful creations in terms of plasticity. By manipulating specific natural elements, the artist transforms them into generalized symbols or metaphors, thus these eight paintings can be called abstract improvisations. These are free-style compositions that abstract the states of nature in winter – temporary, constantly changing and uniquely different each time.

There is no literal narrative in this cycle, thus the paintings are united by a common colour palette, idea, and mood. The motif of a tree receives the most attention in the artist's improvisations, resulting in several variations of depicting trees.
