Zichmni

Zichmni is the name of an explorer-prince who appears in a 1558 book by Nicolò Zeno of Venice, allegedly based on letters and a map dating to the year 1400 by the author's ancestors, brothers Nicolò and Antonio Zeno. Zichmni is described as a great lord of some islands off the southern coast of Frislanda, a possibly fictitious island claimed to be larger than Ireland and located south of Iceland.
