Very nice, once again!  But here are some other readings just
to keep the ball in play.  I'm certainly not wedded to any of

(d) inur (= inar) do fhaoi (= fháigh) gach aos
=   a tunic that each generation has woven

(f) ferr (?) gur bhuain re (= le) baos.
=   better (?) (than) that (he) has won with folly.

I'm not very clear on the expansion of the "f" with the
thingy over it.

But your earlier "fios na n-ôg sna n-aos" seems just as likely.
A perfect pun?

Or possibly "aí" (poetic inspiration, learning)?

"gon aí-s(a) ón aí anuas"
= to this learning down from the (earlier) learning  (??)

Now that I have a photo of the whole page, I've been messing
with brightness and contrast, but no joy.  The notae and such
haven't suddenly revealed their secrets.
