In celebration of National Pet Day (which was yesterday, I know) I have been thinking about these furry little critters. A few years ago the beautiful painting above was unearthed by the National Portrait Gallery depicting three 16th century siblings with their prized pet pig. Oh and a finch which one child appears to have some sort of death grip on. The artist is unknown but it has been dated at around 1580 making it the earliest known depiction of a pet guinea pig. The whole painting just screams 16th century wealth; the ruff, the detailed collars, the headdress, and even their pale faces and reverent stares. There’s no doubt they are from a wealthy family, but were guinea pigs only for the wealthy? and how did they become popular?
From their initial introduction to Europe in the sixteenth century via Spanish traders they seem to have grown in popularity, with even more examples of our furry friends in portraiture from the seventeenth century. The painting below which hangs in the Queen’s dining room at Kensington Palace was purchased by George IV who believed it to be a portrait of Sophia Charlotte, Princess of Brunswick. The painting shows the young girl with all the trappings of the new Dutch aristocracy: sumptuous silk clothing, pearls, formal gardens (indicating a country house), damask curtains and of course a guinea pig which she is gently stroking.
However guinea pigs were not just for the wealthy. In 2007 the remains of a domesticated guinea pig, dating from the late sixteenth century, were found at a site in Mons, Belgium. The skeleton was found in the back garden of a property which didn’t belong to those from the upper echelons of society. An archaeological investigation into the site and remains concluded that guinea pigs were in fact accessible to ‘several classes of the population’ and this led to their popularity across Europe. It makes sense that guinea pigs would have easily become widespread, as a pet they are fairly low maintenance and they are ready to breed from as young as 1 month old, typically birthing around three piglets. 
Food for thought
The study also confirmed that the guinea pig found at Mons was definitely not eaten, due to the preservation of the bones and completeness of the skeleton. I mean I haven’t tried it myself but apparently guinea pig is actually very tasty, so good for them managing to not gobble them all up. We are talking about a time where throughout Europe people still ate dormice, porcupines and hedgehogs! .
