A Veil is a chalk drawing which shows Hawkins developing themes which are reminiscent of Odilon Redon and of pastels by Fernand Khnopff, such as his Voile series. Although it has been claimed to date from around 1890, it seems more likely that it was made in Hawkins’ final year or two, perhaps 1909.
