BELISAMA OF PTOLEMY. 375 
according to their present configuration, but the 
communication between the two above-mentioned 
rivers is much wider, as well as the bed of the 
Gowy is shown to be much larger than in subse- 
quent maps. Names are, however, unfortunately 
not attached to the several estuaries, which, if 
they had been, would have enabled future to- 
pographists more clearly to have understood 
Ptolemy. 
In Richard of Cirencester’s map, the Mersey 
is named Seteia fluvius, while the Dee is marked 
Deva ; the Ribble, the Belisama ; and the Lune, 
Alauna. 
Cellarius, in his Geography, p. 259, though he 
notices Cambden’s opinion, that the Dee was the 
ancient Seteia, and that the Ribble was Belisama, 
yet says, “ Quod merseyum nune estuarium, a 
Mersey fluvio dictum, videtur Seteia Ptolomer 
esse.” 
D’Anville, again, places Seteta as the Dee 
mouth, and Belisama the Mersey. He affixes 
no name to the mouth of the Ribble, but notices 
Moricambe A’ stuarium in the right place.
