Tivadar Kosztka Csontváry was a Hungarian painter. He was one of the first Hungarian painters to become well known in Europe.
He painted more than one hundred pictures, the most famous and emblematic of which is probably Magányos cédrus (The Lonely Cedar). His art connects with post-impressionism and expressionism, but actually he was an autodidact and cannot be classified into an exact style — he regarded himself as one of the "sunway"-painters (this word was created by him). He was one of the most eccentric and most considerable Hungarian painters.
