"The Wild Duck" By Henrik Ibsen.

In the Wild Duck, Henrik Ibsen begins his play by emphasizing the value of colour and light. He uses the theme of light to contrast Old Werle, a rich man, with Old Ekdal, a poor helpless man. Ibsen connects the colour green with the loss of eyesight of Old Werle. A possible affair between Old Werle and Gina, Hedvig's mother, may suggest the cause of Hedvig's loss of sight. By using sun and moon, Ibsen …

…Werle offers Gregers a partnership in his firm. He tells his son that he is losing his eyesight and needs his help in the business. The poor eyesight is an important point for two reasons. First, Werle is now blinded both physically and emotionally; he has no understanding of the pain he has caused his son or his wife. Secondly, Hedvig's eyes are also weak, indicating she is probably Werle's daughter, which Hjamler later discovers.
