According to its colophon (folio 8 recto), the manuscript is written by Conchubhar for the vicar and parson of Brí Gobhann (Mitchelstown, County Cork) and for the grandson of Robert Condon, all of whom, apparently, have promised to pay him for his work. He adds, apparently by way of warning, that his attorney (tuirrne) is Denis Ó Duinnín; this may be the Donnchadh mac Giolla-na-naomh Uí Dhuinnín who wrote a section of the Yellow Book of Lecan in ?1465. Conchubhar’s script is generally large, ovoid. His only decoration is a large initial A, and his only marginalium, folio 2 recto, is virtually illegible: ‘Ar...u...dar in...ins...is b...cuma limsa an lit…’(?).

The contents are as follows.

Life of Saint Findchua of Brí Gobhann. Beginning ‘A...d brugaid amru ro g...’ (above is an illegible line). Corresponds closely to Stokes, (editor) ‘Lives of saints from the Book of Lismore’, page 84, but continues past the end of Stokes’ edition in two columns, largely illegible, at folio 8 verso. In smaller lettering at folio 8 recto, lower margin, is the colophon: “Misi Concubar ⁊ beatha ⁊ slainti uaim do bicairi ⁊ do peasain Brí Gobann ⁊ do mac mhic Roibeart Contun ⁊ cennchuid amail ro gelladur in mbethaidsi Fhindcaid ⁊ aithnid corub tuirrne dilis damsa Denis O Duindin ⁊ do rindisa amail ro gellus ⁊ fuilngid patruin na tuaithi ⁊ na cilli an digbail risin lebar so ⁊ na sailid na clerig a fhagbail ar deirc na ar guidi ach cuirid fhiacha chugumsa ⁊ guidid ar anmunnaib icarat fein ⁊ na denad in lebar so d’ fillid amail do níat clerig ⁊ leaga do bunad ⁊ na tobrad ar iasacht e ⁊ na tabrad re scribad ⁊ leasaigit fa glas co honorach. Finitt”. There are 3 lines of similarly small script across foot of folio 8 verso: these are illegible.
