Talmud zu Kohelet 1:6

“One makes it rectangular in the four directions of the world^2,Since the Sabbath domain of a built-up area is a rectangle oriented NS-EW one starts measuring from a line, oriented NS or EW, which touches the built-up area but leaves the area entirely to one side of the line. In mathematical terminology the completion of the town is the area enclosed on a map of the town by its support lines oriented NS and EW.⁷²Babli 56a, Tosephta 4:6. R. Yose here is the Tanna, ben Ḥalaphta., so that its Western direction be in the West of the world and its Southern direction be in the South of the world. Rebbi Yose said, if he does not know how to determine the directions let him go and learn from the solstices. From the place where the sun rises on the day of the summer solstice to the place where it rises on the day of the winter solstice is Eastern direction; from the place where the sun goes down on the day of the winter solstice to the place where it goes down on the day of the summer solstice is Western direction; the remainder are North and South. That is what is written⁷³Eccl. 1:6., it goes to the South and turns to the North. It goes to the South during the day and turns to the North during the night; all around in circles goes the wind, to its circuits returns the wind, these are Eastern and Western directions⁷⁴The main directions of the wind..”
