Wyndham Lewis said it took him the strength of seventeen water buffaloes to paint Praxitella, one of the most iconic and enigmatic 'portraits' of the early 20th century. Over 100 years after it was first shown in the exhibition 'Portraits and Tyros' in 1921, Lewis's painting was subject to investigation at Courtauld Conservation which revealed startling outcomes. This focused exhibition tells that story, the people involved in its making, some whose voices have been eclipsed, and looks at the wider social terrain to ask how it affects its meaning for us today.
