The Roman History · Amm. 22.15.31

There is also Syene, where at the time of the summer solstice the rays surrounding upright objects do not allow the shadows to extend beyond the bodies. And if any one fixes a post upright in the ground, or sees a man or a tree standing erect, he will perceive that their shadow is consumed at the extremities of their outlines. This also happens at Meroe, which is the spot in Ethiopia nearest to the equinoctial circle, and where for ninety days the shadows fall in a way just opposite to ours, on account of which the natives of that district are called Antiscii.
