The most feared crime is that which they call sumban, which is incest in the first degree; for they regard it as assured by long experience and knowledge inherited in tradition from their ancestors, that the land which allows that crime is bound down by wretchedness and misfortunes until its infamy is purged by the rigorous chastisement of the offender. There is no other means which can placate the wrath of heaven. Consequently, when they suffer long droughts, or other general plagues from heaven, they immediately attribute them to this. A case of that nature came to my notice in the year fifty-one, when the drought was general, and so great that even the water of the rivers failed, and that river which had any water that found its way to the sea was rare. The Indians of the village which was in my care on the coast of Siocon came to tell me that it was a punishment from the sky, and that it had been demanded by the awfulness of such crime on the coast of Mindanao, where they said that a mother was living in marriage with her son. They petitioned me to have the offenders punished, and warned me that the punishment should be death without remission, such being their custom, without admitting satisfaction by any other penalty, however excessive it be. The same report was current in the island of Basilan. However, it was without other foundation than that the Indians are gossipy and suspicious, ignorant of the secrets of the sky and ruled by the traditions of the past. They are ruled in that island by greater fear, as they retained more accurately in their memory certain cases that served them as examples and warnings. For, at a certain time, the sky was so leaden that for two years not a drop of rain fell. There was an Indian who violated the respect that he owed to his blood and to nature, with regard to a daughter of his. Although he tried to bury the crime in the depths of his silence, it cried out to the sky as an offense, and was heard distinctly as a sin; for the effect, as ungrateful as evil, always turns against its cause. He was a person of influence, and respect for him did not allow any investigation to be made; but, the villages grieving over the public calamity, and unable to endure their forced famine, men trampled under foot respect and laws, in their judgment that tolerance in so execrable an evil had also vexed and hardened the sky. By common consent they seized father and daughter, and, shutting them up in a cage well weighted with stones, threw them into the sea. In return they experienced from the sky approbation for their avenging zeal, in the heavy rain with which it received them. For at all times God preserves the credit to virtue, and even among barbarians imposed penance on vice, so that those who became familiars of vice could have no excuse. [64]
