Sandra Rato and her father Ivo Rato worked together in the research and writing of Chariot of Knowledge: The Lost History of the Ancient Olympic Games. Their investigation of the Ancient Olympics' secret history is grounded in their Lusitanian (Portuguese Celtic) heritage, and was refined through Sandra's studies in archaeology and anthropology at La Trobe University. Their shared journey towards publishing this book began with a re-enactment of the ancient Isthmian Games in Melbourne in 1990, paying homage to Greek culture while shining light on the games' connection with Celtic sporting traditions.
