In four ancient Babylonian cuneiform tablets, Jupiter’s displacement along the ecliptic is computed as the area of a trapezoidal figure obtained by drawing its daily displacement against time, the first evidence for the use of geometrical methods in Babylonian mathematical astronomy.

History, Physics
A new examination of earlier versions of the Astronomical Book is offered, using a mathematical analysis of the figures and astronomical theories presented throughout the Aramaic Astronomy Book; the results fit both the data preserved in the scrolls and the mathematical approach and religious ideology of the scroll's authors better than the details found in the late Ethiopic texts.
