An older writer, quoted in the Book of Lecan, tells a plainer tale. He does not admit the truth of the ancient mythology, and says that the Tuatha De Danann were a remnant of the fallen angels. They assume, he says, bodies of airy substance so as to become visible to men, the better to tempt them. They come at the call of sorcerers and those who practise malevolent incantations by walking in circles lefthandwise. They used to be worshipped, and it was they who invented the spells sung by smiths and druids and wise-women and pilots and cupbearers. From them druidism came in Ireland. The poet-historians did not succeed in killing off the Tuatha De Danann. In 1088 the annalist Tigernach died, and in 1084, four years before his death, his chronicle contains an account of a pestilence which visited Ireland at that time. The cause of this pestilence, says the chronicler, was revealed in that year to a certain man, Gilla Lugán, who was in the habit of frequenting a fairy mound at Hallowtide, the old heathen festival of Samhain. There in the year 1084, Oengus appeared to him and told him that the plague was brought to Ireland by legions of evil spirits from the islands of the northern ocean, who spread it over the country with their fiery breath. And Gilla Lugán himself, says the chronicler, afterwards saw one of these demon legions on the rath of Mullaghmast, and in whatsoever direction their fiery breath came on the land, there the plague broke out among the people. In _Agallamh na Seanorach_, the rulers of the Tuatha Dé Danann are still alive in St. Patrick's time, and inhabit the hills associated with their memory. One of them has recently come to life once more in Dublin, Finnbheara of Cnoc Meadha. From the hills at Tourmakeady you can see Cnoc Meadha, a low round hill, on the eastern horizon. It was pointed out to me by a man who knew all about it. That is where Finn Bheara lives, he said. He is the king of the Good People. He is not always there. When Finn Bheara is living in Cnoc Meadha, it is a good year for the country. When he goes away, it is a bad year. A poem in Duanaire Finn tells how Oengus aided the Fiana in their hostilities with king Cormac, and, like the gods in the Homeric poems, remained invisible while he fought on their behalf. The passage already cited from the Book of Lecan tells how the Tuatha De Danann arrived in Ireland. They came, it says, without ships or boats and first alighted on Sliabh an Iarainn, in the heart of the country.
