The first known report of Amerimutts comes from the Spanish missionary Hernando de Luna y Arellano, member of the jesuit mission of Ajacan, in the current Florida. A kind and religious man, he suffered a crisis of faith during his mission in the Americas, before returning to Spain and dying in his birthplace Toledo. The forensic report written by his personal doctor states that he died while screaming the words "el monstruo" incoherently. After his death, a piece of paper that seems to describe his encounter with an Amerimutt was found among his belongings
"Oh, Holy Mary, Help of Christians, I commend myself unto you, for my spirit is plunged in the deepest of sorrows! It was fated unto me that my footsteps met with a most wretched creature of the devil, whose form I will detail below as a warning for future travelers of these places. So use my words as a guide to avoid these beasts.
I was walking through the bay of Santa María, happily contemplating upon the beautiful landscape, when an ugly being arose out of a nearby bush. His skin was a dirty, coppery hue, darker than that of the Indians who inhabit these lands. Strange marks and symbols adorned his skin, the most profound of them a kind of yellow letter 'M' emblazoned upon his broad forehead. It measured about seven feet in height, its size being considerable, as of a pig or a wild boar. Wide nostrils and tiny, distant eyes adorned his grotesque face, which seemed to writhe and distort with odd gestures. He wore ragged clothes adorned with several white and red stripes and white stars on a blue background. At first, I believed this creature to be no more than a strange species of macaque that the natives had disguised as a prank, but my views changed as the creature spoke."
