Note 298 — Chapter V · THE FOUR KINGDOMS.
Reading edition
Nectan is said to have reigned 20 years, and Cinioch 19; together 39 years. Tighernac, however, records the death of the previous king Gartnaidh in 599, and of Cinadon in 631, giving an interval of only 32 years. Cinioch therefore began to reign in 612, and as Tighernac does not record the death of Nectan as king of the Picts, he must then have been displaced.
