Via Heavenfield, I've learned that Rachel Bromwich has passed away at the age of 95.
Professor Bromwich, more than any other scholar, has influenced my work; my website (and really, my life) would be much poorer if I'd never come across her writings.
Her Trioedd Ynys Prydain is one of the most important works on Old Welsh literature--really, if you're interested in Welsh literature and legend, you can't just pick up a copy of the Mabinogion, you have to seek out TYP. The notes alone are an impressive encyclopedia of Welsh myth and legend. And her works on Welsh Arthuriana in general are without match. She also was instrumental in translating the works of Sir Ifor Williams, whose studies on Taliesin are among the best.
She published an updated edition of TYP as late as 2005; I can only hope to be as active at that age (or live that long).
