 The "Ystorya Adaf" survives in four manuscripts, Peniarth 5, Peniarth 7, Peniarth 14, and Havod 22, and has been edited three times.The version in Peniarth MS. 5 misleadingly titles the work "Euengl Nicodemus" ("Efengyl Nicodemus", "Gospel of Nicodemus").Although the Nicodemus legend and the Rood legend commonly became attached to each other in many medieval permutations, the Welsh text is not one of them.
