This is the story of the Taking of Sid. There was a wonderful king who reigned over the Tuatha Dé in Ireland, Dagan was his name [ie "Dagda"]. Great was his power, even over the sons of Mil, after they seized the lands. For the Tuatha Dé wasted the grain and the milk of the sons of Mil until they made a treaty [cairdes] with the Dagda. Subsequently, they kept their grain and their milk for themselves.
The Taking of the Sid
Great too was his power [ie in Dagda] when he was king at the beginning, and it is he who distributes the síd between the Fir Dé ["men of the gods"]: Lug son of Eithliu to Síd Rodrubán, Ogma to Síd Aircheltrai, the Dagda itself had Síd Lethet Lachtmaige. […]
It is said, however, that Síd Broga [ie Brug na Boinne] belonged to him at the beginning. [Oengus Mac Ind Oc] came to Dagda to obtain his territory when he had made the distribution among everyone; he was one of the foster sons of Midir de Bri Leith and Nindid the prophet.
"I have nothing for you," said the Dagda. “I have completed the distribution. "
“Give me then,” Mac Oc said, “just a day and a night in your own home. It was granted to him then.
“Now go back to your home,” said the Dagda, “because you have used up your time. "
“It is clear,” he said, “that the whole world is day and night, and that is what has been granted to me. "
The Dagan departed from there, and the Mac Oc remained in its síd. It is a wonderful land. There are three trees that bear fruit perpetually, and a pig still alive and on the hoof, and a boiled pig, and a vessel of excellent liquor, and it never diminishes.
