Γεννήθηκε στην Αθήνα το 1935. Σπούδασε ζωγραφική στην ΑΣΚΤ και χαρακτική στην αντίστοιχη σχολή του Παρισιού. Διαμόρφωσε ένα προσωπικό ύφος με ανθρωποκεντρικό περιεχόμενο, κατορθώνοντας να μεταβάλει τις μορφές που απεικονίζει με σχηματικό περίγραμμα, σε σύμβολα, όπως ελέχθη, μιας εικαστικής πραγματείας της καθημερινότητας. Ασχολείται με τη ζωγραφική και τη χαρακτική.

Was born in Athens in 1935. He studied painting at the Athens School of Fine Arts under Professor Moralis (1956 - 1960). A French government scholarship enabled him to study lithography in Paris (1960 - 1963). His work has been widely exhibited in Greece and abroad. He has also produced sets and costume designs for the theatre, as well as illustrations for various books and publications. Fasianos lives and works in Athens and Paris.

Fasianos is one of Greece’s foremost contemporary artists and his work is popular with audiences young and old. His work is typified by ageless figures, often naked and with their hair streaming in the wind. In an instantly recognisable, highly personal, style his work has been described by Le Figaro's Jean-Marie Tasset as "dazzling draughtsmanship which is reminiscent of Matisse". To mark Fasianos’ 70th birthday in 2005, the National Art Gallery in Athens organised a major retrospective of 300 works in oil, while a major book on his work was published in Paris by Editions La Difference.
