It was a table of chords for angles in a circle of large fixed radius. Incidentally, his table was not in terms of degrees, but “steps”, each step being 1/24 of a circle. Later, Ptolemy (100–178 C.E.) constructed a more complete table of chords.

WebPtolemy was the next author of a book of chords, showing the same Babylonian influence as Hipparchus, dividing the circle into 360 ° and the diameter into 120 parts.
