    "obj_descr": "A tripartite sundial from Tell Er Ras, Zeus Temple, Mt Gerizim, (by R. J. Bull, Drew University, USA). Bull: The sundial, formed from a block of local limestone 440 mm long, 300 mm wide and 325 mm high, has suffered damage, especially to its top and back. As a result, most of its dimensions and many of its details have been determined. At the back of the limestone block two spaces, each in the shape of a quarter-sphere, one at either end of the block, have been hollowed out of the stone. This triple sundial probably functioned in the following manner:  If the limestone block was positioned so that Sundial 3 was oriented to the east and Sundial 2 to the west, Sundial 1 would face north. The rising sun would cause two shadows to be cast, one by the gnomon on the face of Sundial 1, the other by the gnomon of Sundial 3. Both shadows would move from the first hour, A, progressively through the six hours of the morning until the sixth hour, noon, vertical shadows would lie along the lines marked by the numeral F. Observer A facing south and looking at the north face of Sundial 1 would in the course of the morning hours see the gnomon shadow progress from its right to its left, while at the same time Observer B facing north and looking at Sundial 3 would see the gnomon shadow progress in the course of the morning hours, from left to right. As the afternoon progressed the shadow on the dial of Sundial 1 would continue to progress from right to left through the last hour of the day. At the same time Sundial 3 would increasingly fall into shadow whereas from the hour of noon, the gnomon shadow on Sundial 2 would begin to mark the afternoon hours moving from left to right as viewed by Observer B.",

    "df_descr": "At the back of the limestone block two spaces, each in the shape of a quarter sphere, one at either end of the block, have been hollowed out of the stone (figs. 3, 5a, 5b; photograph 2). The vertical axes of these quarter spheres are the intersections of a vertical plane representing the back of the limestone block and the two vertical planes representing the ends of the block. Damage in the past has caused the loss of between 1/3 and 1/2 of each of the 24 cm diameter quarter spheres and the loss of almost all of the lines and numerals once inscribed on their concave surfaces (figs. 4 and 6, photographs 2, 3 and 4). The quarter sphere to the right as one faces the back of the limestone block, Sundial 3 (figs. 4, 5b and 6, photographs 2 and 4), has on its extant surface the remains of five inscribed lines, all of which radiate from point Y at the edge of the quarter sphere. Point Y may be defined as that place on the concave surface of the quarter sphere of Sundial 3 where the vertical plane representing the end of the limestone block and a horizontal plane parallel to and 17 cm above the plane representing the bottom surface of the limestone block intersect (fig. 5b). All five scribed lines radiate at equal angles and divide the lower and larger segment of the surface of the quarter sphere into six sectors. These six sectors and the lines which define them are in turn intersected by three lines approximately 5 cm apart. The three equidistant intersecting lines can perhaps best be visualized as intersections on the quarter spherical surface by three parallel planes 5 cm apart, all inclined at an angle of 33\" from the vertical. These three planes, therefore, are parallel to the reclined plane represented by the surface of Sundial 1.",
