Historical Notes Upon Ancient and Modern Surveying and Surveying Instruments
It would be exceedingly difficult, if not absolutely impossible, to determine how far back the nature, relation and application of lines and angles began to be studied and employed as a useful art in the graphic representation upon maps of part, or of the whole, of the earth's surface. Reference has been made to an ancient Sanscrit manuscript, in which it is stated that the Chaldeans estimated 4 000 steps of a camel to be equal to 1 mile, and that 66.25 of such miles were equal to 1°; and further, from that data, 24 000 miles were deduced as the circumference of the earth.
