Serpent attack

02
Dragon and octopus
In this 1367 nautical chart by Francesco and Domenico Pizzigano, an octopus drags one unlucky sailor off a ship while a dragon flies off with another. In this case, Van Duzer thinks the cartographers believed they were warning of a real danger to mariners. *(Biblioteca Palatina)*

03
Ichthyocentaur
An ichythyocentaur (part man, part horse, part fish) plays a viol while swimming along in Abraham Ortelius's 1571 *Theatrum orbis terrarum*. *(British Library)*
04
Monsters attack
Sea monsters attack a ship off the coast of India in Abraham Ortelius's 1571 *Theatrum orbis terrarum*. *(British Library)*

05
Whales and walrus
Whales smokestack-like blowholes attack a ship in Olaus Magnus's *Carta Marina*. This map is an [absolute treasure for sea monster aficionados](http://stag-komodo.wired.com/wiredscience/2013/09/carta-marina/). Magnus made the original version in black and white in 1539. This image and the one that follows come from a color version created in 1572. *(Sveriges nationalbibliotek)*
06
Walrus
A walrus-like creature hauls out on the coast of what's now Finland in Olaus Magnus's *Carta Marina*. *(Sveriges nationalbibliotek)*

07
Smiling monster
Nothing puts a smile on a sea monster's face like a naked lady in a seashell. The lady here represents Bold Fortune, and she appears in a map made in 1565 by Paolo Forlani. *(Library of Congress)*
08
Aquatic unicorn
This aquatic unicorn adorns a map in Cornelis de Jode's *Speculum Orbis Terrae*, published in 1593 *(British Library)*

09
Bird-fish
This fish-bird hybrid appears in Cornelis de Jode's *Speculum Orbis Terrae*, published in 1593 *(British Library)*
10
Sea elephant
This spiky sea elephant appears in a 1572 map by Tommaso Porcacchi. *(British Library)*

11
Flying turtle
The flying turtle above comes from a map of northern Europe published in 1558. *(British Library)*
12
Turtle-bird
This turtle-like creature appears in a 1578 map by Gerardus Mercator, who invented [the projection that bears his name](http://stag-komodo.wired.com/wiredscience/2013/07/projection-mercator/). *(British Library)*

13
Lobster-fish
The polyp, or octopus, depicted here looks more like a lobster-fish hybrid. It appears in *Hortus sanitatis*, an illustrated encyclopedia published in 1491. Books like this were often an inspiration for cartographers. Van Duzer's book includes an illustration of a similar creature clutching a sailor in its claw. *(British Library)*
14
Many monsters
Abraham Ortelius's 1598 map of Iceland boasts an impressive menagerie of sea monsters, several of which are visible in this detail. *(British Library)*
