Spica is the Alpha star of the Virgo constellation, and lies at a distance of approximately 262 light years from Earth.
According to Barbara Hand Clow, the Spican solar system is inhabited by a higher dimensional humanoid race, that is approx. 13 feet (3.5 meter) tall, and they have been visiting Earth for a very long time. A lot of the Atlantean technology would be from Spican origin. But unlike the Atlanteans, the Spicans are a very well balanced race, with integrated male and female selves. On Spica technology is not abused.
The Spicans would have a "spherical" experience/conception of Time.
