Abstract
In the Prologue to the Commentary on St. John, Albert the Great uses the image of an eagle to describe the main feature of the Evangelist, that’s the contemplation. As an eagle John flew into the sky of Trinity going beyond creatural limitation and living a experience, that can be interpreted like a raptus. For better understanding the contemplation of John, some texts are very important: De resurrectione; Quaestio de visione dei in patria; Quaestio de raptu, in which the german teacher explains in what sense the human intellect can know the divine infinity. About this problem it’s significant the distinction between “quid est” and “ut est” in God. The article closes showing how John represents a model of a dominican friar in some texts of the Commentary.
