About this source
What it is
This is a scan of a manuscript page from the Hamilton 90 codex, held at the Staatsbibliothek in Berlin. The codex is one of the autograph copies of the Decameron, written by Giovanni Boccaccio around 1370. The page has a red decorated initial and a red heading at the top left, and dense brown handwriting in two columns. A red library stamp reading Biblioteca Reale Berolinensis appears near the bottom. The image is a scan, not the manuscript itself.
Why it matters
The Decameron is a collection of stories told by a group of young people who leave Florence to escape the plague. Its opening describes the Florentine plague of 1348, so it is one of the most useful written sources on the effects of the pandemic. Because the codex is in Boccaccio's own hand, it lets students look at the text as the author wrote it.
