Xenagoras (geometer) explained
Xenagoras (Greek, Ancient (to 1453);: Ξεναγόρας), son of Eumelus, was mentioned by Plutarch as having been among the first to make a scientific measurement of the heights of mountains.[1] This Xenagoras estimated the height of the shrine of Apollo atop Mount Olympus as a little more than 10 stadia, that is, roughly 6,096 feet. (The mountain is in fact 9,573 feet.)[2] [3] There are some ancient references to a (now lost) book Measurement of Mountains by a "Xenophon" that some scholars consider to be a reference to this Xenagoras, albeit with the wrong name.[4]
