Ambrose of Milan
Catena Aurea · Lukasevangelium 21
And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring; Men’s hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken. And then shall they see the Son of man coming in a cloud with power and great glory.
All which signs are more clearly described in Matthew, Then shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven.
