Lloyd is to hold the position that geographical knowledge at the time(d) of Herodutus was such that Greeks would know that such a voyage would entail the sun being on their right but did not believe Africa could extend far enough for this to happen. He suggests that the Greeks at this time understood that anyone going south far enough and then turning west would have the sun on their right but found it unbelievable that Africa reached so far south. He wrote: "Given the context of Egyptian thought(d), economic life(d), and military(d) interests, it is impossible for one to imagine what stimulus could have motivated Necho in such a scheme and if we cannot provide a reason which is sound within Egyptian terms of reference, then we have good reason to doubt the historicity of the entire episode."
