The perimeter, according to Nansen based on the 23,800 stadia, was . This number is in the neighborhood of what a triangular perimeter ought to be, but it cannot be verified against anything Pytheas may have said, nor was Diodorus Siculus very precise about the locations of the legs. The "perimeter" is often translated as "coastline", but this translation is misleading. The coastline, following all the bays and inlets, is (see Geography of the United Kingdom). Pytheas could have travelled any perimeter between that number and Diodorus'. Polybius added that Pytheas said he traversed the whole of Britain on foot, of which he, Polybius, was skeptical. Despite Strabo's conviction of a lie, the perimeter said to have been given by Pytheas is not evidence of it. The issue of what he did say can never be settled until more fragments of Pytheas's writings are found.
