To avoid the king's wrath, they smeared dog's blood onto a sleeping Rhiannon, claiming that she had committed infanticide and cannibalism by eating her child.

From then on, he was fostered by Pendaran Dyfed and was "brought up carefully, as was proper, until he was the most handsome lad, and the fairest, and the most accomplished at every worthy feat in the kingdom.

The Irish offer to make peace and build a house big enough to entertain Bendigeidfrân but hang a hundred bags inside, supposedly containing flour but actually containing armed warriors.

As instructed they take the now silent head to the Gwynfryn, the "White Hill" (thought to be the location where the Tower of London now stands), where they bury it facing France so as to ward off invasion.

Pryderi invites Manawydan, Bendigeidfran's brother and a fellow survivor, to live with him in Dyfed, arranging for him to marry his widowed mother Rhiannon.

Pryderi and Manawydan travel to England to make a living from various trades, but were forced to leave one town after another to avoid conflicts with other tradesmen who resented their superior skills.

Some time later, Pryderi receives a number of otherworldly pigs from his father's old ally, Arawn, king of Annwn, which are stolen through trickery by Gwydion, a Venedotian magician and warrior.

Both sides suffer heavy losses, but Math fab Mathonwy, king of Gwynedd is victorious and Pryderi is forced to retreat.

The two contenders meet at a place called Y Velen Rhyd in Ardudwy, and "because of strength and valour and magic and enchantment", Gwydion triumphs and Pryderi is killed.

The Welsh Triads name Pryderi as one of the 'Three Powerful Swineherds of the Island of Britain', referring to an occasion on which he guarded the pigs of his foster-father, Pendaran Dyfed at Glyn Cuch.

"[6][7] Pryderi is named once in the Welsh Triads, as one of the three powerful swineherds[8] while the Stanzas of the Graves refer to his final resting place as: "Aber Gwenoli...where the waves beat against the land.

"[9] The Book of Taliesin poem Song before the sons of Llyr also mentions Pryderi and, as in other texts, associates him both with Manawydan fab Llyr and with the otherworldly fortress of Caer Sidi: The character is also referred to in the works of a number of bards, including Einion fab Gwalchmai, Howel Foel ap Griffri and Cynddelw Brydydd Mawr.
