Damascĭus in Harpers Dictionary of Classical Antiquities
（Δαμάσκιος). A philosopher, a native of Damascus. He commenced his studies under Ammonius at Alexandria, and completed them at Athens under Marinus, Isidorus, and Zenodotus. According to some, he was the successor of Isidorus. It is certain, however, that he was the last professor of Neo-Platonism at Athens. He appears to have been a man of excellent judgment, and to have had a strong attachment for the sciences, particularly mathematics. He wrote a work entitled Ἀπορίαι καὶ Λύσεις περὶ τῶν Πρώτων Ἀρχῶν, "Doubts and Solutions concerning the Origin of Things." Of this only two fragments remain-one preserved by Photius, which forms a biographical sketch of Isidorus of Gaza; the other treating Περὶ Γεννητοῦ, "Of what has been procreated." The remains of this work were edited, with a valuable preface, by Kopp J. (Frankfort, 1828). A Venetian MS. contains an unedited work of his, entitled Ἀπορίαι καὶ Λύσεις εἰς τὸν Πλάτωνος Παρμενίδην, "Doubts and Solutions relative to the Parmenides of Plato."
Damascius in Wikipedia
Damascius (Δαμάσκιος, born in Damascus ca. AD 458, died after AD 538), known as "the last of the Neoplatonists," was the last scholarch of the School of Athens. He was one of the pagan philosophers persecuted by Justinian in the early 6th century, and was forced for a time to seek refuge in the Persian court, before being allowed back into the empire. His surviving works consist of three commentaries on the works of Plato, and a metaphysical text entitled Difficulties and Solutions of First Principles.
Damascius was born in Damascus in Syria, whence he derived his name: his Syrian name is unknown. In his early youth he went to Alexandria, where he spent twelve years partly as a pupil of Theon, a rhetorician, and partly as a professor of rhetoric. He then turned to philosophy and science, and studied under Hermias and his sons, Ammonius and Heliodorus. Later on in life he migrated to Athens and continued his studies under Marinus, the mathematician, Zenodotus, and Isidore, the dialectician. He became a close friend of Isidore, succeeded him as head of the School of Athens in ca. 515, and wrote his biography, part of which is preserved in the Bibliotheca of Photius.
In 529 Justinian I closed the school, and Damascius with six of his colleagues sought an asylum, probably in 532, at the court of Khosrau I of Persia. They found the conditions intolerable, and when the following year Justinian and Khosrau concluded a peace treaty, it was provided that the philosophers should be allowed to return. It is believed that Damascius returned to Alexandria and there devoted himself to the writing of his works.
Among the disciples of Damascius the most important are Simplicius, the celebrated commentator on Aristotle, and Eulamius. We have no further particulars of the life of Damascius; we only know that he did not found any new school, and thus Neoplatonist philosophy ended its external existence. But Neoplatonist ideas were preserved in the Christian church down to the later times of the Middle Ages, notably by means of the tremendous influence exerted by the Pseudo-Dionysian corpus. Mazzucchi (2006) identifies Damascius himself as the author of the Pseudo-Dionysian writings, the "last counter-offensive of the pagan" (l'ultima controffensiva del paganesimo).
His chief treatise is entitled Difficulties and Solutions of First Principles (ἀπορίαι καὶ λύσεις περὶ τῶν πρώτων ἀρχῶν). It examines the nature and attributes of God and the human soul. This examination is, in two respects, in striking contrast to that of certain other Neoplatonist writers. It is conspicuously free from Oriental mysticism, and it contains no polemic against Christianity, to the doctrines of which, in fact, there is no allusion. Hence the charge of impiety which Photius brings against him. In this treatise Damascius inquires into the first principle of all things, which he finds to be an unfathomable and unspeakable divine depth, being all in one, but undivided. His main result is that God is infinite, and as such, incomprehensible; that his attributes of goodness, knowledge and power are credited to him only by inference from their effects; that this inference is logically valid and sufficient for human thought. He insists throughout on the unity and the indivisibility of God. This work is, moreover, of great importance for the history of philosophy, because of the great number of accounts which it contains concerning former philosophers.
The rest of Damascius's writings are for the most part commentaries on works of Aristotle and Plato. The surviving commentaries are:
* Commentary on Plato's Parmenides.
* Commentary on Plato's Phaedo. This work has been erroneously ascribed to Olympiodorus of Alexandria.
* Commentary on Plato's Philebus. Also erroneously ascribed to Olympiodorus.
Among the lost works there were:
* Commentaries on Plato's Timaeus, First Alcibiades, and other dialogues.
* Commentaries on Aristotle's de Coelo, and other works. The writings of Damascius on Time, Space, and Number, cited by Simplicius in his commentary on Aristotle's Physica, are perhaps parts of his commentaries on Aristotle's writings.
* Life of Isidore. Damascius's biography of his teacher Isidore (perhaps a part of the philosophos historia attributed to Damascius by the Suda), of which Photius has preserved a considerable fragment. The text has been reconstructed and translated recently.
* Logoi Paradoxoi, in 4 books, of which Photius also gives an account and specifies the respective titles of the books.
