William Holman Hunt (1827-1910) was an English painter who belonged to the group of artists known as the Pre-Raphaelite Brotherhood.

Hunt's 1853 painting The Awakening Conscience (not The Awakened Conscience), is a work full of symbolism. It depicts a young woman rising from the lap of a man, the implication being that she is beginning to doubt the morality of what she is doing (just as Julia is starting to doubt the morality of her relationship with Charles).
