Theophanes the Greek (Russian: Феофан Грек, romanized: Feofan Grek; Greek: Θεοφάνης; c. 1330/1340 – c. 1410) was a Byzantine Greek artist, active mainly in Russia.
He greatly influenced the style of painting in Novgorod and Moscow in the 15th century. He is also known as being the teacher and mentor of Andrei Rublev, the greatest Russian icon painter of his time.
In Eastern Christianity, an iconostasis (Greek: εἰκονοστάσιον) is a wall of icons and religious paintings, separating the nave from the sanctuary in a church. Iconostasis also refers to a portable icon stand that can be placed anywhere within a church. The iconostasis evolved from the Byzantine templon, a process complete by the 15th century.
A direct comparison for the function of the main iconostasis can be made to the layout of the great Temple in Jerusalem. That Temple was designed with three parts. The holiest and inner-most portion was that where the Ark of the Covenant was kept. This portion, the Holy of Holies, was separated from the second larger part of the building's interior by a curtain, the "veil of the temple". Only the High Priest was allowed to enter the Holy of Holies. The third part was the entrance court.
In Eastern Orthodox Christian theology, the Tabor Light (Ancient Greek: Φῶς τοῦ Θαβώρ "Light of Tabor", or Ἄκτιστον Φῶς "Uncreated Light", Θεῖον Φῶς "Divine Light"; Russian: Фаворский свет "Taboric Light"; Georgian: თაბორის ნათება) is the light revealed on Mount Tabor at the Transfiguration of Jesus, identified with the light seen by Paul at his conversion.
As a theological doctrine, the uncreated nature of the Light of Tabor was formulated in the 14th century by Gregory Palamas, an Athonite monk, defending the mystical practices of Hesychasm against accusations of heresy by Barlaam of Calabria. When considered as a theological doctrine, this view is known as Palamism after Palamas.
Christian mysticism is the tradition of mystical practices and mystical theology within Christianity which "concerns the preparation [of the person] for, the consciousness of, and the effect of [...] a direct and transformative presence of God" or divine love. Until the sixth century the practice of what is now called mysticism was referred to by the term contemplatio, c.q. theoria, from contemplatio (Latin; Greek θεωρία, theoria), "looking at", "gazing at", "being aware of" God or the divine. Christianity took up the use of both the Greek (theoria) and Latin (contemplatio, contemplation) terminology to describe various forms of prayer and the process of coming to know God.
Contemplative practices range from simple prayerful meditation of holy scripture (i.e. Lectio Divina) to contemplation on the presence of God, resulting in theosis (spiritual union with God) and ecstatic visions of the soul's mystical union with God. Three stages are discerned in contemplative practice, namely catharsis (purification), contemplation proper, and the vision of God.
The Transfiguration of Jesus is an event described in the New Testament where Jesus is transfigured and becomes radiant in glory upon a mountain. The Synoptic Gospels (Matthew 17:1–8, Mark 9:2–13, Luke 9:28–36) recount the occasion, and the Second Epistle of Peter also refers to it.
In the gospel accounts, Jesus and three of his apostles, Peter, James, and John, go to a mountain (Mount Tabor, later referred to as the Mount of Transfiguration) to pray. On the mountaintop, Jesus begins to shine with bright rays of light. Then the Old Testament figures Moses and Elijah appear, and he speaks with them. Both figures had eschatological roles: they symbolize the Law and the prophets, respectively. Jesus is then called "Son" by the voice of God the Father, as in the Baptism of Jesus.
