The terra-cotta balls found in these strata are especially remarkable, owing to their most varied symbols. I will describe two of these, found at a depth of 5 meters (16½ feet). The surface of the one is divided by lines into eight equal parts;[168] in one of these is a sun with ten rays, of which only four are straight, all of the others seem to represent religious symbols. One ray has the form of the Phœnician letter “Nun,” and must denote lightning; another ray has the form of a serpent; another again the form of the numeral III.; a fourth is the shape of a sign-post; and the remaining two in the form of fishing-hooks; beside the sun is a star. In the next division is a tree with eight branches, a quadrangle with two stars, and a triangle with four stars. The third field contains a tree with twelve branches; a circle with a star; and, beside and above a stroke, twelve stars, one of which has a dot in the centre. The twelve little stars may possibly denote the twelve signs of the zodiac, which, being the twelve stations of the sun, are personified in the Rigvêda by the twelve Adityas, sons of Aditi, the indivisible and infinite space. The fourth field contains a tree with only six branches, a triangle with three compartments, in one of which is a stroke, and also two squares. The fifth field has again a sun with six crooked rays and one straight ray. The sixth field has five divisions: in the first there are five, in the second four, and in the third seven little stars; the fourth division contains a sign resembling the numeral II., together with three stars; in the fifth division there is a simple cross. In the seventh field is a tree with ten branches. In the eighth field there is a figure like a serpent, and a star.
Upon the second terra-cotta ball there is a sun with thirteen straight rays; further there are, between two 卐, three groups of three stars each, and four straight lines; lastly, below the sun three similar lines and three stars.[169] We also frequently find in these strata terra-cotta balls completely covered with stars; likewise an immense number of the round terra-cottas in the form of tops and volcanoes, more than half of which are adorned with the most various symbolical signs. We have also discovered here many weapons of diorite and hard green stone, as well as a number of whetstones of black and green slate with a hole at one end.[170] The use of these whetstones is not very clear to me, for, as I have already said, in the depths of from 7 to 4 meters (23 to 13 feet) I have found no trace of any metal beyond the two nails and the piece of silver wire. However, we came upon a few fragments of moulds for casting instruments, and hence it is probable that copper was known. In any case, however, it was rare and costly, for otherwise I should not have found such colossal masses of stone instruments.
