Antonio Villas Boas (1934-1992) was a Brazilian farmer claimed to have been abducted by extraterrestrials in 1957. Though similar stories had circulated for years beforehand, Villas Boas' claims was among the first alien abduction stories to receive wide attention.
According to Boas, he first attempted to leave the scene on his tractor, but when its lights and engine died after traveling only a short distance, he decided to continue on foot. However, he was seized by a five-foot tall humanoid, who was wearing grey coveralls and a helmet. Its eyes were small and blue, and instead of speech it made noises like barks or yelps. Three similar beings then joined the first in subduing Boas, and they dragged him inside their craft. Once inside the craft, Boas said that he was stripped of his clothes and covered from head-to-toe with a strange gel. He was then led into a large semicircular room, through a doorway that had strange red symbols written over it. (Boas claimed that he was able to memorize these symbols and later reproduced them for investigators.) In this room the beings took samples of Boas' blood from his chin. After this he was then taken to a third room and left alone for around half an hour. During this time, some kind of gas was pumped into the room, which made Boas become violently ill.
Shortly after this, Boas claimed that he was joined in the room by another humanoid. This one, however, was female, very attractive, and very naked. She was the same height as the other beings he had encountered, with a small, pointed chin and large, blue catlike eyes. The hair on her head was long and white (somewhat like platinum blonde) but her underarm and pubic hair were bright red. Boas said he was strongly attracted to the woman, and the two had sexual intercourse. During this act, Boas noted that the female did not kiss him but instead nipped him on the chin and, like the others he had encountered, made barking noises instead of speech.
When it was all over, the female smiled at Boas, rubbing her belly and gestured upwards. Boas took this to mean that she was going to raise their child in space. The female seemed relieved that their "task" was over, and Boas himself said that he felt angered by the situation, because he felt as though he had been little more than "a good stallion" for the humanoids.
Boas said that he was then given back his clothing and taken on a tour of the ship by the humanoids. During this tour he said that he attempted to take a clock-like device as proof of his encounter, but was caught by the humanoids and prevented from doing so. He was then escorted off the ship and watched as it took off, glowing brightly. When Boas returned home, he discovered that four hours had passed.
Antonio Villas Boas later became a lawyer, married and had four children. He died in 1992, and stuck to the story of his alleged abduction for his entire life.
According to Researcher Peter Rogerson, the story first came to light in February, 1958, and the earliest definite print reference to Boas's story was from the April-June 1962 issue of the Brazilian UFO periodical SBESDV Bulletin. Rogerson notes that the story had definitely circulated between 1958 and 1962, and was probably recorded in print, but that details are uncertain.
Boas was able to recall every detail of his purported experience without the need for hypnotic regression. Further, Boas' experience occurred in 1957, which was still several years before the famous Hill abduction which made the concept of alien abduction famous and opened the door to many other reports of similar experiences.
Researcher Peter Rogerson, however, doubts the veracity of Boas's story. He notes that several months before Boas first related his claims, a similar story was printed in the November 1957 issue of the periodical O Cruzeiro, and suggests that Boas borrowed details of this earlier account, along with elements of the contactee stories of George Adamski. Rogerson also argues:
