I usually only have "hazy memory" but this stuff is certainly familiar. It
would seem to be derived comprehensively from traditions of the "petitiones
Patricii" which go back in various forms to the 7th century Latin Lives (or
the Book of Armagh, I'd better say).
I don't have time to check just now, but as far as I remember there are
different groupings of these petitions, with some overlap, and these ones
here strike me as being closer to the Tírechán ones than Muirchiú's. Again,
excuse me if my memory is even smaller (or weaker) than I think, ut memory
recalls the petitions being granted in the Muirchiú text as Patrick agreed
not to be buried in Armagh(!!). If I'm correct on that, this text is closer
to the Tírechán stuff than the Muirchiú material in its setting also.
However the transmission would not have been direct and the petitiones can
be tracked through the other Latin Lives and probably the Vita Tripartita as
well. I'll check this when I get the chance to open that box - the one
labelled "Pandora's". It will be interesting to see how close a verbal
agreement there is to any previous text.
