Abstract
We propose here the first translation into Portuguese of Giovanni Pico della Mirandola’s small treatise De Ente et Uno (1491). The translation is preceded by a brief presentation in which the work is contextualized within the scope of the thought of its young author and in the Florentine philosophical environment of the end of the Quattrocento. In the aftermath of the controversies between defenders of Plato and defenders of Aristotle, a quarrel brought by Greek and Byzantine intellectuals into Italy, who exacerbated the differences between the two philosophers, there were also others who tried to show the essential concord between them, a purpose of which Pico’s treatise is one of the most expressive and relevant documents, seeking to prove the equivalence between Plato’s One and Aristotle’s Being.
