Indeed, if Oenopides did not fix on this or some other figure it is difficult to know in what his achievement consisted, for the Babylonians no less than the Pythagoreans and Egyptians must have realised from early days that the apparent path of the sun was inclined to the celestial equator.

Extractions: General characteristics Latitude 57.0° N Longitude 64.1° W Diameter 67 km Depth Unknown Colongitude 66° at sunrise Eponym Oenopides of Chios References See listing Oenopides is a lunar crater that is located near the northwest limb of the Moon , and so appears foreshortened when viewed from the Earth . This formation lies due south of the prominent Pythagoras crater , and is attached to the southwest rim of 'Babbage E'. The southwest rim of Oenopides is part of the northern edge of Oceanus Procellarum . To the south is the Markov crater This formation is an old crater that has been heavily eroded by subsequent impacts, leaving a low outer rim that is generally hilly and contains a few clefts. There is a gap in the southeast rim, and the level interior is attached to the lunar mare to the south. There are several small craters lying near the eastern rim, and the remainder of the floor is marked by tiny craterlets. To the southwest is the remnant of 'Oenopides R', of which only parts of the rim are still protruding above the surface and the southern rim is completely missing.
