A magical mist arises, and a horseman approaches who throws three spears towards Conn, then asks him and the druid to follow him to his house, which stands on a plain by a golden tree. They enter, and are welcomed by a woman in a gold crown. First they see a silver vat, bound with gold hoops, full of red ale, and a golden cup and serving spoon. Then they see a phantom, a tall beautiful man, on a throne, who introduces himself as Lugh. The woman is the sovereignty of Ireland, and she serves Conn a meal consisting of an ox’s rib 24 feet (7.3 m) long, and a boar’s rib. When she serves drinks, she asks “To whom shall this cup be given?”, and Lugh recites a poem which tells Conn how many years he will reign, and the names of the kings who will follow him. Then they enter Lugh’s shadow, and the house disappears, but the cup and serving spoon remain.[5][6]
