Mathias was born in Uganda, East Africa and first came to Canada in 1967. He studied at the University of Guelph, Ontario and graduated with a B.A. in Fine Art in 1970. He attended the Ontario College of Art in 1971. He also graduated with a Master of Fine Art degree from Wayne State University, in Detroit, Michigan in 1976. The medium of his works is called Intaglio, which involves engraving an impression into a metal plate and then pressing paper over the image to create a beautiful 3D, textured image. The effect should be seen up close, in person to truly be appreciated. His unique works adorn many private homes and public collections around the world.
