"Frederic De Arechaga, also known as Odun, created the Sabaean Religious Order in Chicago, Illinois during the late 1960’s. His family is of Basque extraction, and originally came from Spain. Before becoming the head of this new religion, he lists as previous occupations that of a choreographer and a designer. His mother’s illness prompted Mr. De Arechaga to come to Chicago where he took over her occult supply store, El-Sabarum.
In the 1970’s he changed his name to Odun (pronounced Ordun) Arechaga after his initiation into Santeria. He specialized in studying a god named Obatala. The Sabaean Religious Order was located at 3221 Sheffield Street, Chicago, Illinois 60657--- phone (773) 868-6003. There were also small chapters located in Ohio, Philadelphia, San Francisco, and Fort Lauderdale. The Sabaean religious order also has an official website located at http://www.sabaean.org/
The religion he created is based on his conception of the Sabaean practices of antiquity, Egyptian Mythology, and Babylonian and Sumarian myth along with ancient African theologies.
