The sign which resembles the Phœnician letter “Nun” I found represented sixteen times[163] upon one of those round terra-cottas from a depth of 8 meters (26 feet); for these signs stand in groups of four, and by their position form a cross round the sun, or, if my present supposition is right, round the nave of the wheel representing the chariot of the sun. I also find the symbol of lightning in all the higher strata up to 10 feet below the surface. In all the strata, from a depth of 33 feet up to 1¾ feet below the surface, I find engravings of the sun with its rays innumerable times upon the round terra-cottas, exactly as it is represented on the head of the Sun-god on the metopé which I discovered when excavating the temple; but more frequently still in circles of three, four, five, six or eight double, treble or quadruple rising suns, and in by far the greater number of cases it stands in the centre of four treble rising suns, which form a cross round it. Hundreds of times I find the sun surrounded by stars in the centre of a double or treble cross, which has a large dot on every one of the four ends. These dots probably denote the four nails which fixed the wooden frame by which the holy fire was prepared. At the depth of from 10 to 7 meters (33 to 23 feet) I also found although more rarely, five mystic roses in a circle round the sun. One with signs, which may probably prove to be not merely symbols, but actual letters, I found at a depth of 7 meters (23 feet).[164] I have still to mention those round articles from the same depth, which have three mystic roses and two sheaves of sun-rays in the circle round the sun. Further, from a depth of 9 meters (29½ feet) I have several round pieces, upon which there are 14 crooked sheaves of three sun-rays each, resembling the sails of a windmill, which radiate in all directions from the sun, while the compartments between the sheaves of rays are filled with stars. This representation must indicate the rotation of the wheel in the course of the sun’s chariot in the heavens, that is, if the supposition I before ventured to make, that the round objects represent the wheel, is correct. Another, found at the same depth, has on one side three holy sacrificial altars covered with flames, and a group of stars; on the other side three similar altars, and a suastika forming a cross round the sun.[165] There also occur some with only four curved sheaves of rays, or two 卐 and two flaming altars in a cross round the sun; there is again another upon which two crosses stand opposite each other, and all the rest of the space round the sun (or round the nave of the wheel) is filled with stars. All the whorls met with at a depth of from 10 to 7 meters (33 to 23 feet) are made of clay, for the most part of black or red clay, and as hard as stone, which, in comparison with that of the whorls in the higher strata, is distinguished by its fineness. We also find in these strata some whorls made of lead or fine marble, but they have no decorations.
