A name used for Greenland on several maps and globes of the 16th century - among them, a map produced in 1558 by the Venetian Niccolo Zeno the Younger. It has been substantiated that among Zeno's sources for his map was Olaus Magnus's Carta Marina from 1539, and Claudius Clavus' map from the latter 15th century.

Claudius Clavus, a native of the Danish island of Fyn (Funen), was fairly ignorant of actual Greenland geography - on the "Greenland" on his map (not actually marked by name), he has placed a series of made-up placenames, which can be read as a Funish children's rhyme, beginning with the sentence "There lives a man in a Greenland stream" (or, as Clavus' map has it: "Thær Boer Eeynh Manh Ij Eyn Groenenlandz Aa").

From this rhyme, as it appears on the map, later cartographers borrowed the name EynGroenenland, which became Engronelant.

Which just goes to show that a map is only as reliable as the person who drew it.
