Augustine of Hippo : We know that the stone cut from the mountain without hands is Christ, who came from the kingdom of the Jews without human father: the stone that shattered all the kingdoms of the earth, all the tyrannies of idols and devils; the stone that grew and became a great mountain and filled the whole world. — HOMILIES ON 1 John 1:12 Cosmas Indicopleustes : he speaks of a stone cut out of the mountains without hands, and, in the vision, of the Son of Man coming on the clouds of heaven, whereby he indicates the Lord Christ on both sides of his descent—from Abraham and from the Virgin without human seed, for here the words without hands mean without human seed; while the words on the clouds of heaven are employed because the clouds without human hands carry as it were in their womb the rains to which they give birth. Then again, in the image, the words: And he smote the clay, the iron, the brass, the silver and the gold, and they became like the chaff of the summer threshing-floors, and the wind with its gusts swept them away and there was no more place found for them (Dan. ii, 35); and in the vision the words: I beheld till the beast was slain and his body destroyed, and given to be burned with fire; and as for the rest of the beasts their dominion was taken away, yet their lives were prolonged for a season (Dan. vii, ii), signify respectively the same thing—namely, that at the coming of the Lord Christ all these empires would be taken away—the Babylonian, the Median, the Persian and the Macedonian, while all the kingdoms that arose from the partition of the last would become of no account. And such was the very condition of things in the time of Christ, for neither did the Babylonian, Median, Persian nor Macedonian empires then exist, but they had all been destroyed — The Christian Topography, Book 2 Cosmas Indicopleustes : A stone was cut without hands, and it brake in pieces the clay, the iron, the brass, the silver and the gold, and it filled the whole earth. — The Christian Topography, Book 5 Gregory of Nyssa : The thing is, I think, a dark saying, a shadow of what should come. For what is the stone that is laid but Christ Himself? for of Him Isaiah says, "And I will lay in the foundations of Sion a costly stone, precious, elect:" and Daniel likewise, "A stone was cut out without hands," that is, Christ was born without a man. For as it is a new and marvellous thing that a stone should be cut out of the rock without a hewer or stone-cutting tools, so it is a thing beyond all wonder that an offspring should appear from an unwedded Virgin. — ON THE BAPTISM OF CHRIST Hippolytus of Rome : "Thou sawest till that a stone was cut." Thou sawest, as it were, a stone cut without hands, and smiting the image upon its feet. For the human kingdom was decisively separated from the divine; with reference to which it is written, "as it were cut." The stroke, however, smites the extremities, and in these it broke all dominion that is upon earth. — Hippolytus Exegetical Fragments - Scholia on Daniel Hippolytus of Rome : After these things, what does Daniel say? "A stone was cut without hands and struck the image." [Daniel 2:34] For in all events after the iron was mixed with clay and spread to the tips of the toes and while they are discordant with one another of the seed of men, what is left which is necessary to await but Christ who comes from the heavens as a stone which is cut from a mountain, so that he removes the kingdoms of this world, but also sets up the heavenly kingdom of the saints which will never be destroyed, and the same mountain also became the city of the saints which fills all the earth. — Commentary on Daniel 2.13
