To see how, we must adopt two ideas that are unique to the mathematical culture of the Old Babylonian (OB) period, between the 19th and 16th centuries B.C.E. First we abandon the notion of angle, and instead describe a right triangle in terms of the short side, long side and diagonal...
Textual evidence for such a foot measure was recently found by D. Panchenko (2016). The author noticed that the measurements of the famous tunnel in Samos, reported by Herodotus, gave 8 feet as the height and the width, and 3 feet for the width of the canal inside the tunnel. Archaeolog...
