The medieval era
Perhaps, quite simply, Elizabeth loved Dafydd, and was blind to his faults.
The same could be said of Llywelyn ap Iorwerth’s feelings for Joan. Despite her affair with William de Braose, when Joan died, Llywelyn paid for the construction of a priory at Llanfaes on Anglesey where she was buried. Her coffin lid, which still survives and is now in Beaumaris church, is of the highest quality. It is perhaps not unconnected that soon after her death Llywelyn suffered a stroke from which he never fully recovered.
Gruffudd ap Cynan’s (1055-1137) wife Angharad inspired similar devotion. When he died he left her the port of Abermenai on Anglesey, where he first landed when he came from Ireland to claim his inheritance as Prince of Wales.
