h its handles omitted, no. 129. One half of 1.4472 equals .7236. This is the reciprocal of 1.382, showing that the 1.382 rectangle is composed of two 1.4472 rectangles. Cf. diagram XXX. The relation appears also in the following equation : 1 1.382 = .691 = 2 1.4472 It is noteworthy that one of the… … Diagram XXX. Relation between the rectangles 1.4472 and 1.382 Two 1.4472 shapes, placed one above the other, have the ratio 2.8944 (recip- rocal: .3455 = .691 -f- 2). Two lekythoi, nos. 166, 170, exhibit this proportion. The lekythoi are illustrated in diagram XXXI. The lid of the stamnos, no. 51,…
