The famous map of Iceland surrounded by sea-monsters

One of the most famous printed maps, renowned for its depiction of over a dozen exotic sea-monsters surrounding Iceland, polar bears on iceflows and the volcano Hekla in the interior. Ortelius based the cartography on a map by Gudbrandur Thorlaksson (1542-1627), Lutheran bishop of Hólar, which was the most accurate up to that time. However he augmented the map with the sea monsters from the very rare woodcut 'Carta Marina' of Scandinavia by Olaus Magnus, 1539. The Latin text on the verse includes the key describing each of the creatures. Ortelius's version first appeared in an atlas in 1587, in the 'Additamentum IV', an appendix of 22 new maps not featured in the last full 'Theatrum Orbis Terrarum'.
