After a brief period living in Cape Town he returned to London in 1964 to begin a teaching post at St Martin's and the Central School of Art and Design.
For the New Generation show in 1965 he exhibited a series of polychromatic sculptures taking the form of abstract shapes cut out of sheet aluminium, placed flat on the ground or stood on edge.
Bolus was part of a generation of sculptors inspired by the constructivist work made by Julio González and Pablo Picasso and continued by David Smith and Anthony Caro.
He studied with David Annesley, Tim Scott, William G. Tucker, Phillip King and Isaac Witkin.
[6][7] Bolus worked as an assistant to Anthony Caro throughout his career and was regarded highly for his ability to manipulate difficult materials such as Gold and Silver[8]
