Proclus

Proclus Lycaeus (/ˈprɒkləs ˌlaɪˈsiːəs/; 8 February 412 – 17 April 485 AD), called the Successor (Greek Πρόκλος ὁ Διάδοχος, Próklos ho Diádokhos), was a Greek Neoplatonist philosopher, one of the last major Classical philosophers (see Damascius). He set forth one of the most elaborate and fully developed systems of Neoplatonism. He stands near the end of the classical development of philosophy, and was very influential on Western medieval philosophy (Greek and Latin).

Biography

Proclus was born February 8, 412 AD (his birth date is deduced from a horoscope cast by a disciple, Marinus) in Constantinople to a family of high social status in Lycia (his father Patricius was a high legal official, very important in the Byzantine Empire's court system) and raised in Xanthus. He studied rhetoric, philosophy and mathematics in Alexandria, with the intent of pursuing a judicial position like his father. Before completing his studies, he returned to Constantinople when his rector, his principal instructor (one Leonas), had business there.

Proclus of Constantinople

Saint Proclus (died July 446 or 447) was an Archbishop of Constantinople. He is venerated as a saint in the Catholic Church and the Eastern Orthodox Church.

Biography

The friend and disciple of Saint John Chrysostom, Proclus became secretary to Archbishop Atticus of Constantinople (406–425). who ordained him deacon and priest. Atticus' successor, Sisinnius I (426–427), consecrated him Bishop of Cyzicus, but the people there refused to receive him, and he remained at Constantinople. On the death of Sisinnius, the famous Nestorius succeeded as Archbishop of Constantinople (428–431), and early in 429, on a festival of the Theotokos (Virgin Mary), Proclus preached his celebrated sermon on the Incarnation, which was later inserted in the beginning of the Acts of the Council of Ephesus.

When Archbishop Maximianus (431–434) died on Great and Holy Thursday, Proclus was immediately enthroned by the permission of the Emperor Theodosius II and the bishops gathered at Constantinople. His first care was the funeral of his predecessor, and he then sent to both Patriarchs Cyril of Alexandria and John of Antioch the usual synodical letters announcing his appointment, both of whom approved of it.

Proclus (crater)

Proclus is a young lunar impact crater located to the west of the Mare Crisium, on the east shore of the Palus Somni. It lies to the south of the prominent, terraced crater Macrobius, and west-northwest of the lava-flooded Yerkes. Between Proclus and Yerkes, on the edge of the mare, are the Promontories named Olivium and Lavinium.

The rim of Proclus is distinctly polygonal in shape, having the shape of a pentagon, and does not rise very far above the surrounding terrain. It has a high albedo, being second only to Aristarchus in brightness. The interior wall displays some slumping, and the floor is uneven with a few small rises from slump blocks.

The crater has a notable ray system that extends for a distance of over 600 kilometers. The rays display an asymmetry of form, with the most prominent being rays to the northwest, north-northeast, and northeast. There is an arc with no ejecta to the southwest. These features suggest an oblique impact at a low angle. The rays indicate the crater is part of the Copernican System.
