Quid est quod dicit: Et audivi vocem viri inter Ulai, et clamavit, et ait: Gabrihel, fac intelligere istam visionem? quis ille est qui Gabrieli praecepit, ut Danielem faciat intelligere visionem? Judaei Michaelem autumant. Et cur vocatur Gabrihel, ut intelligere faciat, et non alius vocatur angelus? Quia cum visio de praeliis erat, regumque certaminibus, immo regnorum successionibus, dignum erat ut Gabrihel, qui praepositus est praeliis, huic officio manciparetur.   Quare tempore quo erat Dominus nasciturus, ad Zachariam et ad Mariam Gabrihel missus est, et non alius angelus? Quia, ut dictum est, praeliis est praepositus, indicturus bellum daemonibus, et triumphaturus de mundo venit. Petrus Archidiaconus  Liber De Diversis Quaestiunculis  Source:  Migne 96 1356

What is this that is said: And I heard the voice of a man between the Ulai gates And it called out and said, 'Gabriel, give understanding to this vision. 1 Who is it that commands Gabriel that he give understanding to the vision of Daniel? The Jews say it is Michael. And why is Gabriel called, that he give understanding, and not some other angel? Because the vision was about war, and the strife of kingdoms, and the successions of kingdoms, and rightly was it Gabriel, he who is first placed in struggles, who was given this office. Why in the time when the Lord was to be born was Gabriel send to Zachariah and Mary and not some other angel? Because, as said, he is first placed in struggles, and he came to declare the war against devils and the triumph over the world. Peter of Pisa, The Book of Diverse Questions 1 Dan 8.16
