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.

The research for this publication was funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) under Germany´s Excellence Strategy – EXC 2176 'Understanding Written Artefacts: Material, Interaction and Transmission in Manuscript Cultures', project no. 390893796. The research is part of project RFA08 and was conducted within the scope of the Centre for the Study of Manuscript Cultures (CSMC) at Universität Hamburg.
