Like many members of the Welsh gentry, Herbert was a notable
bardic patron. He was the principal patron of
Ieuan Deulwyn, and was also a patron of
Guto'r Glyn as well as others. He hosted a bardic debate at Coldbrook House between Deulwyn and
Bedo Brwynllys. He was eulogized by Ieuan Deulwyn, Bedo Brwynllys,
Hywel Dafi, and (jointly with his brother William)
Huw Cae Llwyd.[3]
Like his brother, he was a supporter of the
House of York during the
Wars of the Roses. He fought alongside his brother at the
Battle of Edgcote (a victory for rebels who supported the Earl of Warwick and the Duke of Clarence), where he was captured and executed. He is interred with his wife at
Abergavenny Priory, near other members of his family.[4]
