‘The calendar preceded the measures, and we should not be surprised to find that the word mensuration is still in force to describe accurate measurement of quantity - length, areas, volume.’

‘It involves the solution of polygons given certain sides and angles between them, their mensuration, division by diagonals, circumscribing polygons around circles and inscribing polygons in circles.’

‘This section on mensuration certainly has more in common with Hindu and Hebrew texts than it does with any Greek work.’

‘Similarly, even as sophisticated quantitative mensuration came gradually to supersede the qualitative analyses of medieval science, alchemists and astrologers serenely continued their work.’
