Mark Lang is an oil painter primarily known for his complex re-interpretations of the history and mythology of painting. He combines elements of art historical works within imagined environments, creating new contexts for viewing and ordering these images from a contemporary perspective. His unique use of re-framing and mise en abime creates a dialogue between the old and the new, the figurative and the abstract, the authentic and the fake. There is often a subtle sense of humour present in these re-imaginings. The incorporation of figures depicting people he knows, as well as casting himself in different roles through self-portraiture, adds another more personal element to his work.

He studied at the Alberta College of Art and Design in Calgary, and at The School of Visual Arts in New York City, before moving to Montreal where he and his wife raised three children. He currently lives and works in an old church in the eastern townships.

He has received private and public grants for his painting, which has been exhibited in galleries and art fairs in Canada and the United States. His paintings are in various collections internationally.
