Book X, Epigram 28 (Ker)

Father, most fair, of the years and of the bright universe, whom first of all Gods public vows and prayers implore, thou, pervious once, didst aforetime inhabit a petty house, wherethrough populous Rome wore her thoroughfare. Now is thy threshold encircled with Caesarean offerings, and as many forums thou numberest, Janus, as the faces thou bearest. But do thou, hallowed sire, thankful for a gift so great, guard thy iron portals with a bolt ever undrawn.
