Joris Hoefnagel was a Netherlander who lived from 1542 to 1601. He was born to wealthy merchant parents, and traveled around Europe with them in his youth, drawing his experiences. While working in Munich, he was commissioned to produce a four-volume book on natural history. The book is known as the Four Elements, and each volume is named after a different element: Animalia rationalia et insecta (ignis); Animalia quadrupedia et reptilia (terra) ; Animalia aquatilia et conchiliata (aqua); and Animalia volatilia et amphibia (aier). Guinea pigs appeared in the earth (terra) volume (right next to porcupines)
