Antonio Villas Boas

Antônio Vilas-Boas (1934–1991) was a Brazilian farmer who later became a lawyer and is known for one of the earliest and most detailed abduction accounts in modern UFO history. On 15 October 1957 he reported that, at age 23, while working his fields near São Francisco de Sales in the state of Minas Gerais, he was taken aboard an egg-shaped craft by humanoid beings, subjected to a medical examination and forced into sexual intercourse with a female entity.

• Born 1934 in Brazil, died 1991; first a farmer, later a lawyer
• Abduction report of 15 October 1957 in fields near São Francisco de Sales in Minas Gerais
• Observed a red light in the night sky while ploughing
• Described an egg-shaped craft with a spinning top and three legs
• Medical examination and intercourse with a female entity aboard the craft; subsequent radiation-sickness symptoms (nausea, weakness, headaches, skin lesions)
• Investigated by Dr Olavo Fontes of the National School of Medicine of Brazil, who diagnosed "mild radiation sickness"
• Journalist José Martins first heard the account after placing a newspaper advertisement seeking UFO witnesses
• Vilas-Boas could recall every detail without hypnotic regression; media attention built slowly over several years
• Sceptical critics regard the account as a hoax; Vilas-Boas maintained his story throughout his life

For the UAP timeline, Vilas-Boas is the earlier precedent of the Hill abduction: his 1957 report established core narratives (medical examination, small humanoids, physiological after-effects) four years before Betty and Barney Hill — and, with Olavo Fontes's medical assessment, even with a documented clinical finding. The case remains a reference point in every debate on early Latin American abduction reports and their comparability with later U.S. cases.
