The manus dei or hand of God is an artistic convention first seen on some of the posthumous coins of Constantine the Great. Here a chariot with several horses and presumably driven by Constantine himself is received by God represented by the hand of God. The other picture is of an anonymous Byzantine seal of the 11th-12th century which shows us the manus dei in a different context. Mary is shown orans (praying with outstretched hands) from the side with her face partially turned to the viewer. The hand of God is in the upper right. The usual thing is that there is no representation of the infant Christ in any of the myriad ways usually found with Mary. This is called the Theotokos Hagiosoritissa which has to do indirectly with the pose and directly with a church of Mary that supposedly contained the cincture of her garment. In the upper right field; to her left and right we find MHP- ΘV (Mary Theotokos). On the reverse: U CΦPA | ΓIC EIMI | THN ΓPAΦ | HN OPWI | MAΘ in five lines. “Observe the documents to learn whose seal I am”. Hence this is an anonymous seal since one has to break the seal and read the document before ascertaining from whom it comes."
most definitely Constantine, per our primary source on this- Eusebius "At the same time coins were struck portraying the Blessed One on the obverse in the form of one with head veiled, on the reverse like a charioteer on a quadriga, being taken up by a right hand stretched out to him from above."

Neat! I had no idea this was an ancient motif, though I suppose I shouldn't be surprised to learn that. Here is a nice, big medieval coin I had with the Manus Dei device at 12:00: FRANCE, Metz. Civic issue. 14th-16th century. AR Gros (3.01 gm) Boudeau 1659; Saurma 1896/927; Roberts 8932. Toned, gVF
Here it is on this little Eudoxia AE I once owned in my first Roman collection. I recognized the circular thing as a wreath, but the little blob at the top of it just didn't say "hand" to me, somehow. More "manus pumilio" than manus dei, perhaps?
