Parts of ten quires survive, most of which were originally eight folios. It is possible to estimate that some seven or eight quires are missing from the Temporale, and a similar number from the Sanctorale; thus what survives is approximately one-third of the original missal. Of these, only ff 14-15 and 42-43 provide musical notation.

Measurements are approximate, as the manuscript is charred.

Many two-line lombardic initials, usually in blue, with red hairlines; also one-line initials, often alternating red and blue, with hairlines. Elsewhere in the missal larger (four-line) foliate initials are present. The initial on f. 43r is burnished with gold.

Donated to the Kilkenny and South-East of Ireland Archaeological Society (forerunner of the Royal Society of Antiquaries of Ireland) by
Rev John L. Irwin, Rector of Thomastown, Co. Kilkenny, in January 1854.
He had received the manuscript from an English friend; according to Rev Irwin’s account, ‘It was found a few months since built up in the wall of a very old house in the parish of Asprington (sic), near Totnes’.
