The Antônio Villas-Boas Abduction

On October 16, 1957, Brazilian farmer Antônio Villas-Boas claimed he was abducted by small humanoid beings who forced him to mate with a female humanoid. His account, reported before the “alien abduction” narrative became established, contains details that would appear in later cases.

The Encounter

Villas-Boas was plowing fields at night when a craft landed. Small beings dragged him aboard, stripped him, took blood samples, and left him in a room where a humanoid female initiated intercourse. Afterward, she pointed to her belly, then the sky.

Physical Evidence

Dr. Olavo Fontes examined Villas-Boas and found lesions consistent with radiation exposure.

Why It Matters

This case occurred before Betty and Barney Hill, before the abduction genre existed. Elements that became standard—medical examination, reproductive interest, physical aftereffects—appear here first.

Villas-Boas maintained his account until his death in 1991.


In 1957, before anyone knew what abductions should look like, a Brazilian farmer described what would become the template. He went to his grave insisting it happened.
