The founding took place on June 13, in the presence of Captain Grajera and his guard, a few San Juan neophytes, and many gentiles, Presidente Lasuen performing the ceremonies, aided by Padres Peyri and Santiago. Fifty-four children were baptized at the same time, and from the very start the Mission was prosperous. No other missionary has left such a record as Padre Peyri.
This Mary was a certain Jewess, who, condemned to death, and thrown over the Peña Grajera, invoked the aid of the Virgin, and was saved. Another tomb is that of Prince Don Pedro, son of Enrique II., who fell out of a window of the Alcázar. His nurse, according to the tradition, threw herself out of the window after her charge, and together they were picked up, one locked in the arms of the other.
