Colin Gill was the first artist to win a scholarship to The British School at Rome and Allegory was the major painting produced during his stay at the school. Allegory includes portraits of Gills fellow Rome Scholars, the engraver Job Nixon, the Sculptor Alfred Hardiman (and his wife), and  the Rome Scholar in Painting, J M Benson, (and his future wife Maria Rosa Toppi) and Winifred Knights. Knights - the first woman to win a scholarship to the British School at Rome.  Knights arrived just as Gill was completing the canvas, at the end of 1920.  The two fell in love (love Sonnets by Gill include the line ' You hold my heart like a bird in a cage' ) and Gill painted Knights striking portrait over a Calvary.
