An apocryphal work giving an account of the trial, death, and resurrection of Christ. In some MSS an independent treatise on the Descent of Christ into Hades is attached to it; the two together are sometimes known as the ‘Gospel of Nicodemus’. The first part, the ‘Acts’ proper, is probably not earlier than the 4th cent. The second part purports to have been written by the sons of the aged Simeon. The work forms the basis of the medieval play-cycle on the Harrowing of Hell and of the legends of St Joseph of Arimathaea and the Holy Grail.
