Resumen: Studies on Eusebius of Caesaraea's Life of Constantine surmise that there could be an intertextual relationship between this text and Plutarch¿s Life of Alexander. It has been said, for example, that Eusebius may have had in mind a passage from this Life (Alex. 1.2-3) when he declares (VC 1.10) that he will act as a painter in order to compose a verbal portrait of the emperor in his encomium. This contribution analyzes the alleged parallelisms between the two works in order to elucidate if they are significant.
