Aristoteles in Ancient Greek!

„What type of housing are we to build for slaves and freemen, for women and men, for foreigners and citizens?“ And then he answered, „Forwell-being and health, the homestead should be airyin summer and sunny in winter. A homestead possessing these qualities would be longer than it is deep; and its main front would face south.”
