John Everett Millais’s vividly detailed painting Ophelia (1851–52) depicts the drowning of Ophelia from Act 4, Scene 7 of William Shakespeare's Hamlet. Elizabeth Siddal, an artist and Pre-Raphaelite artist’s model, was required to pose in a bathtub of water for hours at a time, kept warm by lamps underneath. On one occasion she caught a severe cold, sometimes attributed as pneumonia.
