"I had you elected, out of friendship for your family, to the sacred college of the Arval Brethren"

The Fratres Arvales ("Brothers of the Fields") were a body of priests who offered annual sacrifices, in May, to guarantee good harvests. The order dated back to the time of Numa Pompilius, the second King of Rome (reigned 715-673 BC), and centered around the worship of the Dea Dia, a fertility goddess, probably an aspect of Ceres.
