Byam Shaw, (full name: John Byam Liston Shaw, 1872 – 1919) was a British painter known for his scenes of history and mythology. Like many of his Royal Academy contemporaries, he went to great lengths to make studies before he began the final painting.
For example, on one of his masterpieces, "Love's Baubles," he went to the trouble to make charcoal drawings of the nude figures beneath the costumes.
This makes a big difference for getting the action of the pose right, especially with voluminous costumes.
And the hair is not an accident either. Shaw did careful studies to work out the braids and the locks. It all shows in the final painting.
