CASTELLUM MENAPIORUM mentioned by Ptolemy (Ptol. 2.9), who says, then after the Mosa, the Menapii, and a city of theirs Castellum.It is also supposed by D'Anville that it may be the Castellum Oppidum quod Mosa fluvius praeterlambitof Ammianus (16.25). But the words Castellum Oppidum quodare said not to be in the MSS. (See the note of Valesius.) As there is a place called Kesselon the left bank of the Maas, between Ruremondeand Venloo, it is supposed that this may be the Castellum Menapiorum; for it would come within the limits of the Menapii.
