As regular readers will know, I have been interested in the so-called Master of the Murano Gradual for several years, despite knowing very little about Italian illumination. My interest in locating the surviving examples of his work perhaps go back to about 2014, when I first started to get interested in the 1838 Ottley sale (e.g. here), which included several. From 2016 I began to pass relevant images and bits of information such as auction-catalogue references to Stephanie Azzarello, who was doing her PhD on the artist and his manuscripts , and to Bryan Keene, who was also interested in the artist, as I had no intention of doing anything serious with the material myself. They have now collaborated on two articles published in the last few years:
Bryan C. Keene and Stephanie Azzarello, ‘Uno splendido enigma: Il Maestro del Graduale di Murano’, Alumina, 64, 2019, 14–21
Stephanie Azzarello and Bryan C. Keene, ‘Splendors of the Serenissima in a Digital Age: The Master of the Murano Gradual Reconsidered’, Manuscript Studies: A Journal of the Schoenberg Institute for Manuscript Studies, 6.2 (2021), 223–67 
The second of these appeared very recently, and as it includes the most extensive list of the cuttings from the Murano Gradual, with their provenances, it has prompted me to sort through my miscellaneous notes, and I intend to blog a series of observations and thoughts, with a few corrections, additions, and questions, in the hope that they will also contribute to future studies.
One "correction" (if I am not myself mistaken) concerns the iconography of a cutting now at the Musée Cluny in Paris, shown above.
