An icon is not a portrait or a religious painting but a window onto the Kingdom, written (not merely painted) according to a received grammar. Its every feature is theological. The Seventh Ecumenical Council (787) confirmed that the honor we give the icon passes to the person it depicts, for since God became visible in Christ, He and His saints may be shown.
The grammar of the icon
- Gold background
- Not a place but the uncreated light of God's Kingdom, eternity rather than a landscape. The figures stand already within heaven.
- Inverse perspective
- Lines open outward toward the viewer instead of receding to a vanishing point, so the icon reaches out to you rather than drawing you into an illusionary depth. The point of meeting is the person who prays.
- No cast shadows
- The saints are filled with light and cast no darkness; their bodies are shown transfigured, already sharing in the life of God.
- Elongated, stilled figures
- Bodies are spiritualized rather than naturalistic, the flesh quieted and at peace, to show humanity restored and deified, not anatomy.
- Large eyes, small mouth
- The senses are reordered toward God: eyes and ears enlarged to behold and hear Him, the mouth small, for the saint lives in prayerful silence rather than appetite or chatter.
- The inscription
- An image becomes an icon when it is named; the inscribed name binds it to its prototype. Christ is marked IC XC (and in His halo the words “He Who Is”), the Theotokos MP ΘY, “Mother of God.”
- The halo
- Not a flat disc of fame but the uncreated glory, the grace of the Holy Spirit shining from within the saint who has become light.
How the saints are depicted
A saint is shown not as he looked on a given day but as the Church knows him: the same recognizable face from icon to icon, with attributes that tell you at a glance who he is and how he served Christ.
- A Gospel or scroll
- Marks a teacher of the Church, the evangelists, the great hierarchs and fathers, and the hymnographers, who handed on the word of God.
- A cross in the hand
- A small upright cross is the sign of a martyr, the witness who bore the Cross of Christ to the end and holds the instrument of his own victory.
- Bishop's vestments
- The omophorion, a wide band over the shoulders, with a hand raised in blessing, shows a bishop; the great hierarchs are vested so and usually hold the Gospel.
- Armor and weapons
- Armor, a spear, or a sword marks the warrior saints (George, Demetrios, Theodore); their true warfare is spiritual, the weapons a sign of the struggle against the unseen enemy.
- A church in the hands
- A saint holding a model of a church is its founder or builder, the bishop or monastic who raised that house of God.
- The monastic habit
- The dark habit, and above all the schema with its cross and instruments of the Passion, shows a monastic who took up the life of repentance and stillness; ascetics are often shown gaunt and weathered by their struggle.
- A physician's case
- A small box or medical instruments belong to the Unmercenary Healers (Cosmas and Damian, Panteleimon), who healed without payment, for they had received the gift freely.
Certain compositions recur so widely that they have names of their own. The most common show Christ and His Mother, each carrying a particular truth.
- The Pantocrator
- Christ “Ruler of all,” shown to the waist, blessing with one hand and holding the Gospel in the other, the face at once merciful and just. It is the great icon of the dome, Christ reigning over His Church.
- Not Made by Hands
- The face of Christ alone upon a cloth (the Mandylion), recalling the image tradition says He left on a towel for King Abgar of Edessa: the first icon, given by the Lord Himself, and the answer to every objection against images.
- The Hodegetria
- The Theotokos “who shows the Way”: she holds the Christ-child on one arm and gestures toward Him with the other hand, pointing us not to herself but to her Son.
- The Eleousa
- The “Tender Mercy”: Mother and Child press cheek to cheek, His arm about her neck, an image of intimate love already shadowed by the Passion she will share.
- The Platytera
- The Theotokos with hands raised in prayer and the Christ-child within a medallion at her breast, “wider than the heavens,” for she contained the One whom the heavens cannot contain. It is commonly placed in the apse, above the altar.
- The Deesis
- “Intercession”: Christ enthroned at the center, the Theotokos and St. John the Forerunner inclined toward Him in supplication on behalf of all, the Church's prayer for mercy gathered around the One who is both Judge and Savior.
Iconographic readings explain the received tradition; recensions vary, and an icon is finally read by praying before it, not by description. Feast images are public-domain or Creative Commons works from Wikimedia Commons.
