The discovery of a 500 year-old poem pasted in the back of a a 1561 edition of works by Geoffrey Chaucer sparked an investigation into the poem and its author, Elizabeth Darce.
“On the one hand it’s not brain surgery. It’s not a major discovery like DNA or something. But I think I’m right in saying that we don’t have any other nonreligious Latin poetry written by a woman possibly at all—and certainly in this period. So it’s the only love poem written in Latin by a woman ever until maybe the 18th century. That’s kind of astonishing really.”
