Before making additions to, and subtractions from, the recently published list, it may be worth summarising the evolution of the cuttings' attribution, as the history of scholarship is somewhat complex:
- An unidentified French (Parisian?) owner had a series of the cuttings which s/he attributed to a 15th-century Spanish illuminator; we know this because some of them are inscribed on the back "Ecole Espagnole / XVe siecle":
- In 1901, Robert Forrer  published brief descriptions and images of nine cuttings which he had bought in Paris, which he attributed to a late 13th-century northern Spanish illuminator under Italian influence ("scheint nordspanischen Ursprunges zu sein, von einem von Italien beeinflussten Meister aus dem Ende des XIII. Jahrhunderts").
- In 1974 at least 6 of Forrer's 9 cuttings were still together , and his attribution was still being accepted: northern Spain, late 13th century.
- In June 1991  a cutting passed through Sotheby's, attributed to northern Spain in the second half of the 13th century.
- A year later, in June 1992  another cutting passed through Sotheby's, still attributed to northern Spain, but now dated to the first half of the 13th century, and compared especially to a Beatus manuscript from San Andrés de Arroyo, Castile, now in the BnF. It was also observed (a fact that seems to have been overlooked in subsequent publications) that the text includes the use of the punctus flexus punctuation, suggesting a Cistercian origin (see the last line, between "posset" and "iussit"):
- Later in 1992  two further cuttings from the series were being attributed by Les Enluminures to "the Master of the Beatus of San Andrés de Arroyo", and dated c.1225; an attribution that was repeated several times in the following years.
- In 1997 Giovanni Valagussa  showed that the series of cuttings were by the same illuminator as some initials in a choirbook in the Biblioteka Jagiellońska in Cracow. The choirbook is liturgically of the Ambrosian Rite, used in the archdiocese of Milan, and it includes the feast of Teodolinda, patron of Monza, just outside Milan, so Valagussa proposed that the artist was Lombard, not Spanish, and named him the Miniatore di Monza. By comparison with other works, he dated the illuminator's activity to c.1280-85.
- In 2013 Gaudenz Freuler  listed the 24 known loose cuttings by the illuminator, all from a Legenda aurea, and accepted that they were by the same artist as that of the Cracow choirbook (whose initials he did not list), and further suggesting the existence of "a further broken-up choirbook", of which only one cutting was known, in the Enrico Frascione collection in Florence.
In 2011 I helped catalogue two cuttings in the Arcana collection, for their sale at Christie's , and observed that the text on their backs is from the collection of saints' lives by Bartholomew of Trent. In 2016 I wrote a blog post in which I observed that the initials in the Cracow choirbook were not integral, but were pasted-in (I was unaware of the fact, as apparently were most other people who wrote about the cuttings, that this had already been noticed ). It follows from this that the date and localisation of the choirbook is perhaps unrelated to the date and localisation of the illuminated initials. I also suggested that the choirbook cuttings are from the same series as the loose cuttings of saints, and that a loose cutting in the Frascione collection (which I have not seen) is also probably from the same series, and not from "a further broken-up choirbook". The number of known volumes to which the artist contributed was therefore reduced from three, to one: all the known initials and miniatures are probably from a single illuminated collection of saints' lives.
Earlier this year, Christopher de Hamel re-examined the question of their date and localisation , largely accepting my proposals, and adding some thought-provoking new ideas:
- that the cuttings were not pasted into Cracow choirbook until the 19th or 20th century, and the stylistic comparanda offered by Valagussa are rather tenuous (in the same way that the comparisons with the Beatus of Arroyo de San Andrés had been rather general);
- that while the manuscript from which the cuttings come must post-date the canonisation in 1228 of St Francis (who is depicted in one of the cuttings), it might pre-date the c.1266-70 publication of Jacobus da Voragine's Legenda aurea, as his text derived, at least in part, from the earlier work of Bartholomew of Trent, completed in 1244.
- that the lavishly-illuminated parent manuscript might have been a presentation copy, perhaps made in the circle of the author, in Trento;
- that even if the manuscript was made it Italy, the illuminator might have been Spanish, perhaps an itinerant Dominican (both Bartholomew of Trent and Jacobus da Voragine were Dominican).
In the next post I will address the issue of the corpus of cuttings that can be attributed to our artist.
EDIT 31 Dec 2018
Unable to read Polish, I had not previously attempted to translate in full the 1953 description of the Cracow manuscript . With the help of Google Translate, I now see that the fact that the initials are cut from another manuscript and stuck in was realised from the beginning (the manuscript was acquired in 1951):
The manuscript itself is unadorned. All the initials contained in it were barbarically cut along the outer contours of some undoubtedly Lombard manuscript, dating back to around 1300, and glued in those places where the needs of the antifonary text required it.
(Sam rękopis jest nieozdobny. Wszystkie zawarte w nim inicjały zostały barbarzyńsko wycięte wzdłuż zewnętrznych konturów z jakiegoś niewątpliwie lombardzkiego rękopisu, pochodzącego z okresu około 1300 r., i naklejone w tych miejscach, gdzie wymagały tego potrzeby tekstu antyfonarza.)
