The AC B tells us that David was born 30 years after Patrick left Menevia:
“Anus sanctus dewy nascitur anno xxx post dis(c)essum patricii de meneuia.”
As the Irish annals say Patrick arrived in Ireland in 432 it follows that David I was born in 462. This is the David whose ancestry is given in the Welsh genealogies and is spoken of in the Historia Regum Britanniae. His death is mentioned in AC C:
“Sanctus Dauid meneuensis archiepiscopus in domino quieuit .”
The death of the later individual, David II, appears in the AC A and B texts respectively thus:
“Dauid episcopus moni iudeorum.”
“dauid meneuensis episcopus obiit.”
The B text has incorrectly interpreted the A text, the last three words of which are “manu in deorum”, that is “in the hands of God”. So, in reality there is no reference to Mynyw. The date of 601 is not totally inconsistent with the Irish annals which date his obit between 587 and 589.
