This title is enclosed in a red rectangle, above and to the right of the start of the story.

O thanic cusna dedenchu do Bec mac De, luid laa fora .s. (slicht?) slog mar oc cuinchid 
fhaitsine fair. 

notes - 
There is a faint spiritus asper over the 't' of 'thanic' and the 'f' of 'faitsine'.

I have not seen the abbreviation '.s.' but I guessed it might stand for 'slicht'.
