The Lebor Gabala records their dramatic entrance to Ireland as follows:
'In this wise they came, in dark clouds from northern islands of the world. They landed on the mountains of Conmaicne Rein in Connachta, and they brought a darkness over the sun for three days and three nights. Gods were their men of arts, and non~gods their husbandmen.'
There are many stories of aerial ships or 'demon ships' ('loinger demnacda') in the Irish annuals.
According to the mythic tales the Tuatha de' Danann were advanced enough to arrive in western Ireland (near modern Connacht) by air. They divided into two social classes:
'gods' as teachers of medicine, smithing, communication or druidry
'non-gods' as farmers or shepherds
Although no one knows for certain what the Tuatha looked like, descriptions, such as of their female war~leader Eriu, indicate tall attractive people with pale skin, high foreheads, long red hair and large blue eyes.
