Aspasius

Aspasius was a 2nd-century Greek philosopher and author. He was a Peripatetic philosopher, and Boethius, who frequently referred to his works, stated that Aspasius wrote commentaries on most of the works of Aristotle. The commentaries explicitly mentioned include those on Aristotle's De Interpretatione, Physica, Metaphysica, Categoriae, and Nicomachean Ethics. A part of the commentary on the Nicomachean Ethics, covering books 1, 2, 4, 7, and 8, is still extant. This commentary was published in Greek as part of Commentaria in Aristotelem Graeca (CAG) vol. 19.1 and was translated into English by David Konstan. It holds the distinction of being the earliest surviving commentary on any of Aristotle's writings. Additionally, Porphyry noted that Aspasius also produced commentaries on Plato's works, and these Aristotelean works were utilized in Plotinus's school. Albert the Great, in his commentary on Aristotle's Politics, mentioned that Aspasius authored a monograph titled "Libellus de naturalibus passionibus" (A small book on natural affections).
