This post is a largely a capture of material I put up on Facebook. Given the difficulty of finding past material on that platform, and that some of my stitching friends avoid Facebook entirely, I add it here. Note that the attributions on these pieces were current as of today – 7 November 2019. If I see that they change, I’ll update this note.
…..Ah, the consistency of museum dating on embroidered artifacts. Here we see two separate accessions, held by the same institution, that present a minor conundrum.

The one on top is Cooper Hewitt Accession 1971-50-86, and is labeled Band (Italy), 17th century. It was a gift by the noted textile curator and collector, Marian Hague (a personal hero of mine). Probably a legacy upon her passing, or part of her personal collection, donated by a later family member.
The one below is Cooper Hewitt Accession 1944-71-5. It’s labled Band (Italy), 16th century. It was given to the museum by Annie-May Hegeman, in 1944. Ms. Hegeman appears to have been a very wealthy individual, from a wealthy family. She collected and displayed many artifacts in her own famous home, and donated many to various museums over a period of decades.
Not only are these two the same design (which I’m graphing up), they are undeniably fragments of the same artifact – yet another example of the “Separated at Birth/Long-Lost Twins” circumstance. You can piece the one below to the right of the one on top, and achieve continuity.
Why the 100 year difference between the two? Different catalogers? Based on updated scholarship? Unknown. Which is correct? Good question. Perhaps detailed analysis of dye chemistry might give a clue, but for these fragment collections – laid down and rarely revisited – it’s not going to happen any time soon.
I find this scholarship of yours fascinating. And why oh why would someone cut them apart? Any guesses to what was in the middle? Thanks for moving this off FB. I hope this is the new book!
Actually, this design will be in a later one. The even more hypothetical THIRD Carolingian Modelbook.
