Slate presents an amazing, interactive digital version of Olaus Magnus’ 1539 Carta Marina, a chart that portrays the sea as teeming with monsters… 

When the chart was made, in the early years of the Age of Exploration, there was a lingering belief in the existence of griffins, unicorns, dragons, the phoenix, the monstrous races, and a host of other unnatural creatures. Modern science was in its infancy. Although adherents to the direct observation of nature would soon challenge hearsay and tradition and begin to classify animal life, at the time the medieval imagination was still free to shape its own forms of the natural world. The chart’s giant lobster gripping a swimmer in its claws, a monster being mistaken for an island, and a mast-high serpent devouring sailors would have represented actual fears of the unknown deep.

Those and Olaus’ other fanciful sea beasts are not mere decorations to fill empty spaces. Nor are they only visual metaphors for dangers lurking in the sea. Intended as representations of actual marine life, they are identified in the map’s key.
