Some confusion has evidently arisen over the placement of Pinna, although I do not share the confidence of ItMiller 214-16 that it can be identified and remedied. On the ground, Pinna lies further inland than Hadria, so it should hardly have been the point where the loop inland from Castro novo linked up again with the coast road. There is no telling whether this misconception is the mapmaker's, or whether it stems from a copyist's slip.
