Now this symbol of the ship, with or without the actual portrayal of the solar emblem, is of very ancient and very common occurrence in the sepulchral art of Egypt. It is connected with the worship of Rā, which came in fully 4000 years B.C. Its meaning as an Egyptian symbol is well known. The ship was called the Boat of the Sun. It was the vessel in which the Sun-god performed his journeys; in particular, the journey which he made nightly to the shores of the Other-world, bearing with him in his bark the souls of the beatified dead. The Sun-god, Rā, is sometimes represented by a disk, sometimes by other emblems, hovering above the vessel or contained within it. Any one who will look over the painted or sculptured sarcophagi in the British Museum will find a host of examples. Sometimes he will find representations of the life-giving rays of Rā pouring down upon the boat and its occupants. Now, in one of the Swedish rock-carvings of ships at Backa, Bohuslän, given by Montelius, a ship crowded with figures is shown beneath a disk with three descending rays, and again another ship with a two-rayed sun above it. It may be added that in the tumulus of Dowth, which is close to that of New Grange and is entirely of the same character and period, rayed figures and quartered circles, obviously solar emblems, occur abundantly, as also at Loughcrew and other places in Ireland, and one other ship figure has been identified at Dowth [Egyptian Solar Bark, XXII Dynasty] Egyptian Solar Bark, XXII Dynasty (_British Museum_) [Egyptian Solar Bark, with god Khnemu and attendant deities] Egyptian Solar Bark, with god Khnemu and attendant deities (_British Museum_)
