According to
Roman mythology told by
Zosimus, the Secular Games originated with a
Sabine man called Valesius, ancestor of the
Valerii. When his children became seriously ill, he prayed to his household gods for their cure, offering to give up his own life in exchange. A voice told him to take them to
Tarentum and to give them water from the
Tiber to drink, heated on an altar of
Dis Pater and
Proserpina. Assuming that he had to travel to the Greek colony of Tarentum in southern Italy, he set out with his children on the journey. Sailing along the Tiber, he was instructed by the voice to stop on the
Campus Martius, at a place which happened also to be called Tarentum. When he warmed water from the river and gave it to the children, they were miraculously cured and fell asleep. When they woke up, they informed Valesius that a figure had appeared to them in a dream and told the family to sacrifice to
Dis Pater and
Proserpina. Upon digging, Valesius found that an altar to those deities was buried on the site, and performed the ritual as instructed. Celebrations of the Games under the
Roman Republic are poorly documented. Although some Roman antiquarians traced them as far back as 509 BC, some modern scholars consider that the first celebration well attested as having taken place was that of 249 BC, during the
First Punic War. But even the historicity of the later republican Secular games of 249 and 146 is disputed. According to
Varro, an antiquarian of the 1st century BC, the Games were introduced after a series of
portents led to a consultation of the
Sibylline Books by the
quindecimviri. In accordance with the instructions contained in these books, sacrifices were offered at the
Tarentum on the Campus Martius over three nights, to the underworld deities of
Dis Pater and
Proserpina. Varro also states that a vow was made that the Games would be repeated every hundred years, and another celebration did indeed take place in either 149 or 146 BC, at the time of the
Third Punic War. However, Beard, North and Price suggest that the Games of 249 and the 140s BC were both held because of the immediate pressures of war, and that it was only with the revival in the 140s that they came to be considered as a regular centennial celebration. This sequence would have led to a celebration in 49 BC, but the civil wars apparently prevented this. ==Augustus==
