The games in which Coroebus was victor, and which form the principal epoch of Greek history, were celebrated about the time of the summer solstice 776 years before the common era of the Incarnation, in the 3938th year of the Julian period, and twentythree years, according to the account of Varro, before the foundation of Rome.
In this way Ninib, whose chief seat appears to have been at Shirgulla (Lagash), became the sun-god of the springtime and of the morning, bringing joy and new life to the earth, while Nergal of Kutha was regarded as the sun of the summer solstice and of the noonday heat - the harbinger of suffering and death.
When the event took place between the summer solstice and the 1st of January following, the sum of the Olympic year and of theyear before Christ is equal to 777.
According to this, the days at the summer solstice were twenty-four hours in length, and conversely at the winter solstice the nights were of equal duration.
Portrayed in hymns and myths as a god of war and pestilence, there can be little doubt that Nergal represents the sun of noontime and of the summer solstice which brings destruction to mankind.
Being informed that at Syene (Assuan), on the day of the summer solstice at noon, a well was lit up through all its depth, so that Syene lay on the tropic, he measured, at the same hour,the zenith distance of the sun at Alexandria.
