Earliest known painting of species revealed for the first time

A painting has been unveiled in London's National Portrait Gallery, of what is believed to be the earliest portrait of a guinea pig.

The painting depicts three Elizabethan children, two boys aged five and six, with a girl aged seven who is cradling a beige, brown and white guinea pig.
 
The portrait was revealed during the making of the exhibition "Elizabeth I and her people", which is supported by the Weiss Gallery and due to open on October 10, 2013.
 
Guinea pigs were introduced from South America by Spanish traders and are said to have been popular pets during Queen Elizabeth I's time.
 
Due to the expensive and fashionable dress of the children in the portrait, it is suspected that they belonged to a wealthy family of nobility or gentry. Portraits of children became popular among the sixteenth century across Europe, as they allowed families to document lineage and fertility.

In the portrait, the youngest boy also clutches a small bird, which is thought to be a finch.

Guinea pigs are not the only animal to feature in the exhibition, as horses, stags and dogs also make appearances, as well as more exotic animals displayed on the subject's jewellery, purses and crests.
 
The exhibition will be open until the new year. Click here for more information.
