The "Ermine" portrait is another of the allegorical portraits of Queen Elizabeth of England.
This is Marileecody.com's description: "Why is Elizabeth seated with an ermine? It was the symbol of royalty; and, if you look closely at the animal, you can see the gold crown it wears. The crown symbolizes majesty and purity. As for the bejeweled black gown and background - black and white were the queen's favorite colors. Also, the deep, dark color reinforces the symbolic gravity of the painting.
In this portrait, Elizabeth wears the famous 'Three Brothers' jewel - a gem made of three diamonds set in a triangle around a pointed diamond. It was one of her most treasured jewels. The sword of state rests on the table beside the queen and symbolizes justice; she also holds an olive branch to symbolize peace."
