This icon, called "The Anastasis" is from the apse of the arekklesion (funerary chapel) of the monastery of Chora at Constantinople. The theology taught by this icon is the quintessence of The Faith. Triumphant Christ is risen and stands over the shattered gates of hell, wherein the Evil One lies bound amid now useless locks, as He raises Adam and Eve from their tombs. Kings David and Solomon with +John the Forerunner watch from the left as Abel, the Protomartyr (and prototypos of Christ) along with other OT figures watch from the right. This icon for us teaches the ultimate Truth. "Christ is Risen and you O Death are annihilated."
A Blessed and Holy Pascha to you and yours, St.AG!
