The Rose of the Winds free pdf Excerpt from The Rose of the Winds: The Origin and Development of the Compass-Card It is no part of the present paper to enter upon the reasons for the irregularities which are found to exist in the directive force of the earth, and which produce those local 'variations' of the compass which the mariner encounters everywhere. Neither is there here any question considered as to the errors or perturbations due to the presence near the compass of pieces of iron on the ship, nor as to those due to the incidental presence of magnetism in the iron of the ship's hull or fittings- nor, again, as to the means for compensating those perturbations or correcting those errors. The compass, as above described, has remained practically unchanged in all essential particulars for four centuries. The compasses carried by Columbus in his voyages of discovery in the West Indies certainly possessed every one of the features enumerated, save that it is doubtful whether all or any of their thirty-two points were marked with initials, and whether in them the North point bore a fleur-de-lis. As will be seen, probably only six of their points were so marked- and almost certainly there was no fleur-de-lis on any of them. For none of the compass-cards which have yet been identified as of earlier date than 1500 bear a fleur-de-lis- and those of them which bear initials carry only the initials of some of the eight principal winds. The windroses (see Fig.7, Plate Iv), on the Mappamundi drawn in 1500 by Juan de la Cosa, who was pilot for Columbus in 1493, have no fleur-de-lis and no initials. Nothing is more perplexing to the student of the history of the compass than the unhistorical way in which the chroniclers have transcribed and transmitted erroneous statements and unfounded assertions, the truth of which should have been tested. Flagrant errors arising from bad copying, or worse etymology, have been sedulously propagated in the interests of mistaken patriotism- and the invention of the compass has been claimed for many different nations on the most absurd grounds. It may therefore be worth while to set down a few of the more important points as now established: 1. The attractive power of the lodestone was known to the ancients, as appears from the writings of Plato and of Euripides- and it was independently known to the Chinese. 2. The fact that this attractive power could be communicated to iron or steel by the lodestone was known to Lucretius and to the Chinese.
