Tibur is my native place, Flavius Agricola my name. I’m the one you see reclining here, just as I did all the years of life fate granted me, taking good care of my little self and never going short of wine. Primitive, my darling wife, passed away before me, a chaste worshipper of Isis, attentive to my needs and graced with every beauty. Thirty blissful years we spent together… … Friends, who read this, do my bidding. Mix the wine, drink deep, wreathed with flowers, and do not refuse to pretty girls the sweets of love. When death comes, earth and fire devour everything.
