Leonée and Richard Ormond's "Catalogue of Oil Paintings, Frescoes and Life-Size Statues" (149-80) lists several other paintings on Shakespearian subjects besides those included here. In some cases the whereabouts of the pictures are presently unknown (untraced).
 
 

• Othello and Desdemona, c. 1849. Untraced.
• The Duel Between Romeo and Tybalt, 1850. Untraced.
• Friar Laurence emerging from his Cell with a Basket, c. 1857. Untraced. (Uncertain if Leighton completed an oil painting on the subject.)
