Frans Post (1612-1680) was a Dutch painter from Haarlem belonging to the Dutch School. Between 1636-1644, he received a commission from John Maurice of Nassau, then governor of Brazil, to travel to Brazil and document its people, nature and landscape.
During his time in Brazil, Post made drawings and sketches of animals, which he probably used as studies for his paintings. Thirty-four of these drawings were recently discovered in the Noord-Hollands Archief. The archive has graciously made the digitised drawings available for re-use on Wikimedia Commons.
