 This picture was shown in the memorable "Ulster Unit" exhibition, held in Belfast in 1934, perhaps Luke's only foray into the avante-garde.His aesthetic otherwise embraced strictly traditional values, much of his inspiration, especially with regard to his interest in tempera painting, being drawn from the early masters of the Italian Renaissance such as Piero della Francesca and Botticelli.In the mid and late 1930s Luke's preoccupation with formal structures began to assume a greater importance in his work.
