It is interpolated with lore not found elsewhere regarding the branches (halls) of the Ulster court at Emain Macha and the shields of the Ulstermen.
In the codex (Book of Leinster, TCD 1339 olim H.2.18), the piece is bound in leaves immediately following the recension of the Táin Bó Cúailnge, and in the Catalogue is listed among the "Prose tales of Conchobar Mac Nessa, Cuchulaind, Athirne, Celtchair.".
[5] Some of the shields are construed to be swords by contemporary translators and dictionarists[6] The lore regarding the great ale/wine vat, Ol n-guala,[7] and the rod with apples/balls for calling the crowd to attention, can be compared with the accounts found in the LU recension of Tochmarc Emer.
[8] This editorial decision is potentially confusing, since for the Tain Bo Cuailnge proper, he uses the first recension and not the Book of Leinster version.
The work also contains interesting passage of hyperboles regarding the heptad of Fergus (Irish: sechtae),[9] omitted by Kinsella, which states how Fergus had the appetite of seven men, a libido that could only be satisfied by seven women in the absence of his wife Flidas, and that the size of his phallus measured seven fists.
