Legenda Aurea: St. Luke

Luke is as much to say as arising or enhancing himself. Or Luke is said of light, he was raising himself from the love of the world, and enhancing into the love of God. And he was also light of the world, for he enlumined the universal world by holy predication, and hereof saith S. Matthew, Mathei quinto: Ye be the light of the world. The light of the world is the sun, and that light hath height in his seat or siege. And hereof saith Ecclesiasticus the twenty-sixth chapter: The sun rising in the world is in the right high things of God, he hath delight in beholding. And as it is said Ecclesiastes undecimo: The light of the sun is sweet, and it is delightable to the eyes to see the sun. He hath swiftness in his moving as it is said in the Second Book of Esdras the fourth chapter. The earth is great and the heaven is high and the course of the sun is swift, and hath profit in effect, for after the philosopher, man engendereth man, and the sun. And thus Luke had highness by the love of things celestial, delectable by sweet conversation, swiftness by fervent predication and utility, and profit by conscription and writing of his doctrine.
