A doctoral thesis is always contaminated by positivism. The study of a scientist ignored his contacts with arts. Talking with the son of his great Friend Jose Pires Goncalves, medical doctor and archeologist, revealed his contacts with Alberto Magnelli and Francois Leger, founders of futuristic painting. As well as Amelia Mendoza, dance Professor and daughter of his Mother, living far from his life, revealed the contact with Jean Cocteau, the smoking of opium together, the possibility of divorce. This artistic contacts have been mediated by Sophie Spira. Giao house, kept in the center of Reguengos de Monsaraz, by the care of Sociedade Portuguesa de Autores, keeps the collection of Art possibly second only to Gulbenkian. Surprises exist in the house- a Art Nouveau bed designed by the scientist, and the room for spiritism- a local and discrete religious tradition, where Sophie and Dr. Talhante, member of the Communist Party (P.C.P.) , Professor of Mathematics at Liceu (high school) invocated with Giao consent. The mysteries of his years in Paris, as well as the hidden or forgotten truths witnessed in the rich house where the loved art contemplated science creativity, are matters for present research for those who can do it.
