He was born in Skiathos on 20th November 1884 and he was related to Papadiamantis on his mother's side. He attended Varvakio for two years where Alexandros Moraitidis taught and in 1901 he received his diploma from the Didaskalion of Athens. In the same year he was appointed in a teaching position in Skiathos where he remained until 1940. In 1920 he attended the Hieratical frontistirion of the Rizarios School for a year. He was ordained priest and immediately became intendant and a prelatic church warden of Skiathos. He died in Athens on 11 July 1960 and his funeral was held on his island with all the inhabitant's pesence.
He was involved from his early years with the folklore of his island supported by his collective ability and conscientious nature. At the same time he showed his love for Byzantine music and hymnography. He had a close relationship from his early years with both Alexandros Papadiamantis and Alexandros Moraitidis and this helped him later, in his intellectual pursuits and performance. Georgios Rigas was a tireless and creative researcher, an authority on matters of the Church Ritual and a folklore researcher characterised by scientific observation, conscientiousness and gravity. He was also a methodic teacher and a master of liturgy. His presence in the school and the church of Skiathos has remained historic.
