eaten by hostile Indians after a shipwreck, changing Nóbrega's mind about the Indian mission. Sensing the difficulties of converting adult Indians to Christianity, Nóbrega determined that the Jesuits' efforts should concentrate on the teaching of children, who were more pliable. The Jesuits started to create elementary schools for teaching Portuguese and Latin, basic literacy, and religion. The Jesuits discovered that singing was a very effective way of winning the attention of the students, and Nóbrega was one of the pioneers in using music in education in Brazil. To help the evangelization of children, Nóbrega had the idea of bringing in seven orphan children to Brazil and making them learn Tupi, the language of the Indians, so that they would be bilingual and act as translators. The children would often go with the Jesuits on foot to faraway places and were protected and cherished by the Indians. Several of the children became Jesuit priests, too. In 1552, Nóbrega again accompanied Tomé de Sousa to the captaincy of São Vicente, in the present-day southern state of São Paulo. There in 1553 he was joined by another group of Jesuits, who had arrived with José de Anchieta, then a young novice, who travelled with Duarte da Costa, the second Governor-General sent by the Crown. Nóbrega determined as the new mission of the small band of missionaries to found villages (aldeamentos) on the high plateau just above the coastline to better pursue their work of catechesis and education of the Indians. Thus, on January 25, 1554, Nóbrega and Anchieta celebrated the first mass in the new and modest Jesuit College of São Paulo dos Campos de Piratininga, in honor of Saint Paul's day of conversion to Christianity. The tiny settlement around this Jesuit school was to become one of the largest metropoles of the world, São Paulo. Missionary practice Nóbrega and his men began catechizing and baptizing the natives upon their arrival in Brazil. One of the early encounters with members of indigenous groups was when Nóbrega and his men tried to stop preparations for a cannibal feast and the natives rose against the Christians. The Governor's militia helped to defend the missionaries against the native uprising. Busy building chapels and schools, the missionaries boasted of the high rate of conversion of the natives. The Jesuits had begun teaching prayers to the natives as well as teaching them how to write and sing. According
