Note 327 — APPENDIX B.
Ernest Georg Ravenstein translation
Ramusio adds: “but with wooden bolts”, but omits the allusion to the loadstone.
Peutinger locates the “calamito or loadstone” near Ceylon. The myth of magnetic mountains and islands originated in India or China, and was widely credited during the Middle Ages. It was believed that the magnet pulled out the iron bolts and nails of passing ships, which then fell to pieces and were lost.
