In Greek mythology, Actis (Template:Unicode) was one of the Heliadae, a son of Rhodus and Helios. Actis, along with his brothers, Triopas, Macar and Candalus, were jealous of a fifth brother, Tenages's, skill at science. They killed him and Actis escaped to Egypt.[1] According to Diodorus Siculus, Actis built the city of Heliopolis in Egypt to honour his father Helios. It was from him that the Egyptians learned astrology.[2]
