The following quote from the Bible Book of Revelation probably served as an inspiration for the Death card of the Marseille Tarot: God sending his sickle (the kundalini energy) to harvest man when he is ready.
Then I looked, and behold, a white cloud, and sitting on the cloud was one like a son of man, having a golden crown on His head and a sharp sickle in His hand. And another angel came out of the temple, crying out with a loud voice to Him who sat on the cloud, “Put in your sickle and reap, for the hour to reap has come, because the harvest of the earth is ripe.” Then He who sat on the cloud swung His sickle over the earth, and the earth was reaped. (Revelation 14:14-16)
The two heads in the foreground, on all three of the above cards, do not appear chopped off and dead, but they are standing upright and looking happy. They resemble new crop emerging from the ground. Significant in this regard is that the coloring suggests that the heads are outside the mowing area of the scythe. The crown they wear is a reference to spiritual completion.
A Bible quote that fits this image of dying and rebirth is the familiar parable of the grain of wheat, from the Gospel of John:
“Truly, truly, I say to you, unless a grain of wheat falls into the earth and dies, it remains alone; but if it dies, it bears much fruit. “He who loves his life loses it, and he who hates his life in this world will keep it to life eternal. (John 12: 24-25)
