The tradition was subsequently confirmed by the statement made by authors of repute, that the city of Amalfi, in order to commemorate an invention of so much importance, assumed a compass for its coat of arms. This was believed till the year 1810, when the coat of arms of Amalfi was found in the library at Naples. It did not answer at all to the description given of it: instead of the eight wings which were said to represent the four cardinal points and their divisions, it had but two, in which no resemblance to a compass could be traced. Later investigations have, as we have said, completely demolished all the arguments by which the compass was maintained to be of European origin and of modern date. The curious reader will find the extracts from Chinese works which substantiate the Chinese claim, in a volume upon the subject published in 1834, at Paris, by M. J. Klaproth, and composed at the request of Baron Humboldt.
In the sketch which we are now about to give of the Portuguese voyages to the African coast, it will be remarked that the compass was already introduced and acclimated. No mention whatever is extant of the first venture made upon the Atlantic under the auspices of this mysterious but unerring guide. Science and history must forever regret that the first European navigator who employed it did not leave a record of the experiment. What would be more interesting to-day than the log of the earliest voyage thus accomplished in European waters? The modern reader would surely give his sympathy, unreservedly, to a narrative in which the navigator should describe his wonder, his terror, his joy, when, throughout the voyage, he saw the tremulous index point invariably north; when, upon the dispersion of the clouds which had concealed the Star from view, it was found precisely where the needle indicated: when, upon its being diverted from the line of direction by some curious and perhaps incredulous experimenter, it slowly but surely returned, remaining fixed and constant through storm and calm, at midnight and at noon. What would be more interesting than the speculations of such a captain upon the cause of the marvellous dispensation? And what more amusing than the commentaries of the forecastle, and the learned explanations of the veteran salts to the raw recruits? But all this absorbing lore has hopelessly disappeared, and the mariner's compass will forever remain mysterious in its principle, mysterious in its origin, mysterious in its history. We shall have occasion to return to the subject from another point of view, when, in describing the Arctic voyages of the present century, we shall find James Clarke Ross standing upon the North Magnetic Pole.
