Measurements of imprints of spectacle frames in the Campione dei Beni, 1504 (Florence, Archivio del Capitolo di San Lorenzo, Ms. 2211)

This dataset was created in the context of the publication A. Janke, C. Colini, K.A. Huskin, S. Bosch, and I. Shevchuk, "A Second Look at Multispectral Data of Late Medieval Music Manuscripts" (in preparation). The research reexamines multispectral imaging (MSI) data of the San Lorenzo Palimpsest (Florence, Archivio del Capitolo di San Lorenzo Ms. 2211), namely the faint traces of spectacles present on fols 4v-5r, 15r, 33r, and 46v-47r (modern foliation). The dataset attempts to reconstruct and measure the spectacles from the imprints that MSI made visible.
