Gruffudd Hiraethog

Gruffudd Hiraethog was a 16th-century Welsh-language poet, born in Llangollen, north-east Wales.
Gruffudd was one of the foremost poets of the sixteenth century to use the cywydd metre. He was a prolific author and gifted scholar. Though he was member of the medieval guild of poets and a notable upholder of that tradition, he was also closely associated with William Salesbury, Wales' leading Renaissance scholar. He is buried in the vault of the St Collen’s [Church, Llangollen|Church of St Collen] in Llangollen.
One of the first Welsh books to be published was Gruffudd's collection of proverbs in 1547, Oll synnwyr pen Kembero ygyd.
