On f. 1 in ink: “Ex libris Dominici Merli Civis Lucensis 1787.” Listed in Bernard Quaritch, A Catalogue of Illuminated and other Manuscripts (London 1931) no. 74; at that time the manuscript was lacking only 2 leaves (first leaf of q. 3 and of q. 16) and contained: “f. 1, Calendar; f. 21, Officium B.M.V. (lacking 1st leaf); f. 141b, Missa B.V.M.; f. 147, Septum Psalmi Penitentiales cum Litania; f. 181, Officium Mortuorum; f. 257, Officium S. Crucis; f. 267, Officium S. Spiritus; f. 290, Memoriae Sanctorum”; at that time it was decorated with 14 illuminated and 3 historiated initials, and with three-quarter borders of “floreated scrolls.” Acquired, still whole except for the two missing leaves, by Nicolas Pavlov, Dobbs Ferry, NY, from Reiss & Auvermann at Glashuetten im Taunus, West Germany (Catalog, lot #15, with plates) in October 1988. Dismembered by Pavlov and portions sold to other dealers. A part, probably the Office of the Dead, was sold to the bookdealer Bruce Guenter of South Egermont, MA.
