Llywelyn ap Gruffudd, the last semi-independent ruler before Edward the First (of Braveheart fame) conquered Wales, was killed in combat in 1282.
On his death, a poet named Gruffudd ab yr Ynad Coch composed an elegy for Llywelyn, but I've only been able to find a (Middle?) Welsh source on Wikisource.
Does anybody know of an English translation? I've looked extensively and can't find any, and the reason I'm asking is apparently the Welsh people at the time found the elegy incredibly moving and poignant, so I'd like to understand it more
Here you go, the spelling of Gruffudd has many variants, in this case using 'Gruffydd' will get you older results as the adoption of Gruffudd, while currently 'correct' is somewhat newer. You can also use Lewelin for Llywelyn.
Edit: It also just occurred that Google's algorithm might also be more aware that I'm interested in scholarly texts as I wrote my dissertation on pre-Conquest Wales.
