Basil the Great
Catena Aurea · Lukasevangelium 12
And he said also to the people, When ye see a cloud rise out of the west, straightway ye say, There cometh a shower; and so it is. And when ye see the south wind blow, ye say, There will be heat; and it cometh to pass. Ye hypocrites, ye can discern the face of the sky and of the earth; but how is it that ye do not discern this time? Yea, and why even of yourselves judge ye not what is right?
(in Hexam. Hom. 6, 4.) Now we must observe, that conjectures concerning the stars are necessary to the life of man, as long as we do lot push our searches into their signs beyond due limits. For it is possible to discover some things with respect to coming rain, still more concerning heat and the force of the winds, whether partial or universal, stormy or gentle. But the great advantage that is rendered to life by these conjectures is known to every one. For it is of importance to the sailor to prognosticate the dangers of storms, to the traveller the changes of the weather, to the husbandman the abundant supply of his fruits.
