A painful incident now occurred. During a council which was held on board the flag-ship, a sharp dispute arose, and Juan de Carthagena, who affected to treat the Captain-general with contempt, having answered him with pride and insolence, Magellan felt obliged to arrest him with his own hand, and to have him put in the stocks, an instrument made of two pieces of wood placed one upon the other and pierced with holes, in which were placed the legs of the sailor who was to be punished. The other captains remonstrated loudly with Magellan against a punishment which was too degrading for a superior officer, and Carthagena in consequence was simply put under arrest, and guarded by one of the captains. To the calms now succeeded rain, tempests, and heavy squalls, which obliged the vessels to lie-to. During these storms the navigators several times witnessed an electric phenomenon of which the cause was not then known, but which they considered an undoubted sign of the protection of heaven, and which even at the present day is known by the name of St. Elmo's fire. Once past the equinoctial line--a passage which does not at that time seem to have been celebrated by the grotesque ceremony of baptism which is in vogue at the present day--they steered for Brazil, where, on the 13th of December, 1519, the fleet cast anchor in the magnificent port of Santa Lucia, now known under the name of Rio Janeiro. This was not, however, the first time that this bay had been seen by Europeans, as was long believed. Since the year 1511 it had been known under the name of _Bahia do Cabo Frio_. It had been visited also, four years before Magellan's arrival, by Pero Lopez, and seems to have been frequented since the commencement of the sixteenth century by mariners from Dieppe who, inheritors of the passion for adventurous navigation of their ancestors the North-men, roamed over the world, and founded small establishments or factories in all directions. Here the Spanish expedition procured cheaply, in exchange for looking-glasses, pieces of ribbon, scissors, hawks' bells or fish-hooks, a quantity of provisions, amongst which Pigafetta mentions pine-apples, sugar-canes, sweet potatoes, fowls, and the flesh of the _Anta_, which is thought to be the tapir.
