A New Perspective on Eratosthenes' Measurement of the Earth.

A more balanced and well-founded assessment is offered: Ptolemy’s reputation is rehabilitated in part, and the delusion of high-accuracy ancient cartography is dispelled.
The article is based on a course of lectures in Ancient astronomy delivered at the international summer school "TEXNH. Theoretical Foundations of Arts, Sciences and Tech- nology in the Greco-Roman
The simplest method to measure the geocentric lunar distance: a case of citizen science
We present the results of measuring the geocentric lunar distance using what we propose is the simplest method to achieve a precise result. Although lunar distance has been systematically measured to

The Eratosthenes-Strabo Nile Map. Is it the earliest surviving instance of spherical cartography? Did it supply the 5000 stades arc for Eratosthenes' experiment?
At the very outset of his account of Egypt, Strabo1 provides a disarmingly crude, thus hitherto-neglected map of the Nile River all the way from Meroe (c. 17° N. latitude) north to the river's
