The Four Branches of the Mabinogi, central stories in the collection now known as the Mabinogion, largely focus on the fortunes and failures of several intertwined mythological Welsh families, mostly notably the House of Dôn and the House of Llyr.
The illustration here shows their most dramatic collision: the warrior-wizard Gwydion striking down Pryderi, King of Dyfed, in a dispute over a herd of magical pigs!
The genealogies of the two families are often ambiguous, and at times contradictory. By one reckoning, Pryderi could be considered the step-grandson of Llyr, through his mother Rhiannon and step-father Manawydan.
Gwydion's connection to the House of Dôn is more clear, being explicitly listed as one of the sons of Dôn.
