Silentium & pax in matrimonio.

Peace and quiet within a marriage.

Qui rem divinam faciunt tibi pronuba Iuno,
Incenduntque aris thura Sabaea tuis:
Fel caesae iaciunt altaria ad ipsa bidentis:[1]
Sic privata suo victima felle manet.

In sancto coniux, debet uterque thoro.

Those who offer you their worship, Juno, goddess of Marriage, and burn Sabaean [Arabian] incense at your altars: Towards the same altars they toss the gall of a slaughtered animal. As a result the victim has none of its bile left. This is the rule for marriage: on the sacred marriage-bed each spouse should lay aside the storms of anger.
