Adomnán, the Senchus fer n-Alban and the Irish annals record Áedán as a son of Gabrán mac Domangairt ( died c. 555 – 560 ).

Gaelic literature in Scotland includes a celebration, attributed to the Irish monk Adomnán, of the Pictish King Bridei's ( 671 – 93 ) victory over the Northumbrians at the Battle of Dun Nechtain ( 685 ).

In book three, Adomnán describes different apparitions of the Saint, both that Columba receives and those that are seen by others regarding him.

According to Adomnán, writing about a century after the events he described, the Irish monk Saint Columba was staying in the land of the Picts with his companions when he came across the locals burying a man by the River Ness.

Adomnán in his Life of Saint Columba offers a longer account, which Abbot Ségéne had heard from Oswald himself.

* Adomnán, Life of Saint Columba translated and edited Richard Sharpe.

Saint Adomnán, Abbot of Iona who died in 704, mentions similar free standing ringed wooden crosses, later replaced by stone versions.

He was a contemporary of Saint Columba, and much that is recorded of his life and career comes from hagiography such as Adomnán of Iona's Life of Saint Columba.

* Adomnán of Iona, Life of Saint Columba, tr.

Saint Serf is said to have been a contemporary of St. Mungo, also known as Saint Kentigern, though if he in fact lived at the same time as Adomnán, this is chronologically impossible.

A Celtic Christian monastery was founded there in the sixth century ; Adomnán names Saint Columba as founder.

The main source of information about Columba's life is the Vita Columbae by Adomnán ( also known as Eunan ), the ninth Abbot of Iona, who died in 704.

There he met Adomnán, Abbot of Iona, who showed him an island in Loch Leven ( later called St Serf's Inch ).

Aldfrith was a close friend of Adomnán, Abbot of Iona from 679, and may have studied with him.

Adomnán, the 7th century abbot of Iona, records Colonsay as Colosus and Tiree as Ethica, both of which may be pre-Celtic names.

Adomnán reports that Rhydderch sent a monk named Luigbe to Iona to speak with Columba " for he wanted to learn whether he would be slaughtered by his enemies or not ".

Adomnán of Iona, writing less than 150 years after Diarmait's death, describes him as " ordained by God's will as king of all Ireland.

* Adomnán of Iona, Life of St Columba, tr.

Adomnán categorizes the Vita Columbae into three different books: Columba ’ s Prophecies, Columba ’ s Miracles, and Columba ’ s Apparitions.

Adomnán tells of Columba ’ s prophetic revelations in the first book.

According to Adomnán, Columba came across a group of Picts burying a man who had been killed by the monster.

Whereas Adomnán just tells us that Columba visited Bridei, Bede relates a later, perhaps Pictish tradition, whereby the saint actually converts the Pictish king.

The earliest report of a monster associated with the vicinity of Loch Ness appears in the Life of St. Columba by Adomnán, written in the 7th century.

While very little in the way of Pictish writing has survived, Pictish history since the late 6th century is known from a variety of sources, including Bede's Historia ecclesiastica gentis Anglorum, saints ' lives such as that of Columba by Adomnán, and various Irish annals.

Likewise, the Cáin Adomnáin ( Law of Adomnán, Lex Innocentium ) counts Nechtan's brother Bridei among its guarantors.

* Adomnán, Life of St Columba, tr.

In the 7th century Adomnán mentions " Rechru " and " Rechrea insula " and these may also have been early names for Rathlin.

* Adomnán, Life of St Columba, tr.

Áedán's brother Eoganán is known from Adomnán and his death is recorded c. 597.

Although nothing is known of Cuildach and Domangart or their descendants, Adomnán mentions a certain Ioan, son of Conall, son of Domnall, " who belonged to the royal lineage of the Cenél nGabráin ", but this is generally read as meaning that Ioan was a kinsman of the Cenél nGabráin, and his grandfather named Domnall is not thought to be the same person as Áedán's brother Domnall.

His succession as king may have been contested ; Adomnán states that Columba had favoured the candidacy of Áedán's brother Eoganán.
