At another island farther to the west, Diaz says: “We found a temple on which stood the great and abominable-looking god Tetzcatlipuca, surrounded by four Indians, dressed in wide, black cloaks, their hair hanging as our canons or Dominicans wear it. These were the priests, who had that very day sacrificed two boys, whose bodies they had cut open and then offered their bleeding hearts to this horrible idol. They were about to perfume us in the same way they had done their gods; but though the perfume smelled like our incense, we would not permit them so shocked we were at the sight of the two boys whom they had recently killed, and we were disgusted with their abominations. Our captain questioned Francisco, the Indian whom we had brought with us from the Rio de Banderas, concerning the purport of all these things, for he seemed to be an intelligent person, we having, at that time, as I have already stated, no interpreter. Our captain interrogated him by signs. Francisco answered that this sacrifice had been ordered by the people of Culua; but, as it was difficult for him to pronounce this word, he repeatedly said, Olua, Olua. In honor of our commander, whose Christian name was Juan, and as the day was the feast of St. John, we gave this small island the name of San Juan de Ulua.” Sailing northward along the coast of Mexico, “we first came,” says Diaz, “in sight of Tusta, and two days after, of the more elevated mountains of Tuspa, both of which take their names from two towns close to these mountains. Along this part of the coast we saw a number of towns lying from six to nine miles inland. It is now the province of Panuco.” On account of the approach of winter, the scarcity of provisions, and the leaky condition of one of the vessels, the explorers determined to return to Cuba; Pedro de Alvarador having previously set sail for the island.
