Being the thirteen treasures of Welsh mythology that feature in both the Mabinogion and the Welsh Triads.
- Dyrnwyn, gleddyf Rhydderch Hael - the Sword of Rhydderch the GenerousIf a well-born man drew it himself, it burst into flame from its hilt to its tip. And everyone who used to ask for it would receive; but because of this peculiarity everyone used to reject it. And therefore he was called Rhydderch Hael, the Generous.
- Mwys Gwyddno Garanhir - the Basket of Gwyddno
Food for one man would be put in it, and when it was opened, food for a hundred men would be found in it.

- Car Morgan Mwynfawr - the Chariot of Morgan
If a man went in it, he might wish to be wherever he would, and he would be there quickly.
- Cebystr Clydno Eiddin - the Halter of Clydno EiddynWhich was fixed to a staple at the foot of his bed: whatever horse he might wish for, he would find in the halter.
- Cyllell Llawfrodedd Farchog - the Knife of Llawfronedd
which would serve for twenty-four men to eat at table.
- Pair Dyrnwch Gawr - the Cauldron of Dyrnwch the Giant
