Seville, May 12, 1521.  The accountant Juan Lopez de Recalde writes to the bishop of Burgos on this date of the arrival of the “San Antonio” at the port of Seville, Las Muelas.  The captain of the vessel now was “Geronimo Guerra, a relative and servant of Cristobal de Haro, and its pilot Esteban, a Portuguese.”  “They brought as prisoner Alvaro de la Mezquita, eldest son of Magallanes’s brother, who was appointed captain of this said ship in place of Juan de Cartagena.”  Mezquita was transferred to a prison on shore, at which Barbosa, “Magallanes’s father-in-law, showed much resentment, saying that he ought to be set free and those who brought him imprisoned.”  The letter relates the discord between Magalhaes and certain of the other officers of the fleet; the imprisonment of Mezquita by Cartagena; the attempted mutiny; the tragic deaths of Mendoza, the treasurer, and Quesada; and other vigorous measures of Magalhaes in quelling the outbreak.  He relates the separation in the strait of the “San Antonio” from the other vessels, and the determination of the men of this vessel to return to Spain, notwithstanding the opposition of Mezquita.  The latter coming to blows with the pilot Esteban Gomez was arrested and “they came direct to this port, eating three ounces of bread each day, because their provisions had failed.  In the judgment and opinion of those who have come, the said Magallanes will not return to Castilla.” (No. xxi, pp. 201-208.)

A journal or log of Magalhaes’s voyage was written by Francisco Albo, covering the voyage from cape San Agustin in Brazil until the “Victoria” [the first ship to circumnavigate the globe] returned to Spain.  The log begins November 29, 1519, and ends September 4, 1522.  The entries are for the most part very brief.  It shows that the fleet sighted or touched at various points, among them “a mountain shaped like a hat, which we called Monte Vidi, now corruptly called Santo Vidio [today Montevideo], [211] and between it and Cape Santa Maria... a river called the Patos River;” also, farther on, “a very great river...  Solis [today Rio de la Plata].”  The record for October 21-December 1, 1520, says:  “On the twenty-first of the said month we took the sun in fifty-two degrees at a distance from land of five leagues.  And there we saw an opening like a bay; at its entrance toward the left was a long sandy point.  The cape we discovered before this point is called Cape Las Virgines.  The point of sand lies in fifty-two degrees of latitude and fifty-two and one-half degrees of longitude.  From this sand-point to the other side is about five leagues.  Inside this bay we found a strait of about one league in width.  From this entrance to the sand-point it is straight east and west.  On the left side of the bay is a large angle in which are many sunken rocks.  But as you enter you keep toward the north, and as you enter the strait you go toward the southwest by a mid channel.  And as you enter you observe
