One of my favorite things about my current podcast and website project is that sometimes I can reunite an outgoing letter with its chancery copy, after six centuries of separation. jonathanseyfried.net/historians-n... #medievalsky #medievalists @medievalists.bsky.social @la-coronica.bsky.social

The outgoing letter, dated May 28, 1387. Note the worm damage pattern that came from the document being stored folded up.

This is the first part of the chancery copy of this document. Source: PARES website, Archival Reference ACA, CR, R1751 f63r (https://pares.mcu.es/ParesBusquedas20/catalogo/show/4801766)

This is the second part, which, intriguingly, ends without a probata. Source: PARES website, Archival Reference ACA, CR, R1751 f63v (https://pares.mcu.es/ParesBusquedas20/catalogo/show/4801766)

I'm excited to attend @imc-leeds.bsky.social for the first time. My paper title: "Sugar, Emeralds, and Unicorn Horn: Merchants and Spicers as Agents of Medicinal Knowledge Transfer in the Late Middle Ages." Also participating in a roundtable: "Teaching Premodern Europe in the American Southwest."
