Manarmanis Portus
Μαναρμανὶς λιμήν
Manarmanis Portus (Μαναρμανὶς λιμήν), a harbour on the west coast of Germany, and probably formed by the mouth of the river Unsingis. It is perhaps identical with the modern Marna in West Friesland, which may even owe its name to the ancient port. (Ptol. 2.11.1; Marcian. Heracl. p. 51, where it is called Μαραρμαρός.)
