This miracle occurred in Seville when the King [Alfonso X] had returned there after making war on the Moors of Granada and on the Genetes and others from Africa. He defeated them all and won their property and possessions. After this, the King became seriously ill, as did his brother, don Manuel.

When don Manuel had recovered from his illness in Seville, he went hunting with one of his falcons, which had molted in the summer. He went out with many falconers, bearing falcons with which to attack herons and cranes.

One of the falcons flew to the other side of the Guadalquivir River and could not be retrieved. They searched for it for three weeks and spread the word, thinking that a farmer may have found it and kept it to sell.

The prince went out again to hunt with his most skilled falconers. On the plain of Tablada, near the village of Coria, they saw a falcon pursuing a bird. They recognised that it was the lost falcon chasing a flycatcher.

They prayed to Santa Maria do Porto to make the bird return, and promised to give her a wax falcon. They called the falcon, but it would not come, because it was eating its pray.

Don Manuel went off by himself and approached the falcon. While he was standing in a freshly plowed field, the falcon crossed the Guadalquivir River and placed the flycatcher at his feet. He praised the Virgin.
