The Cross of Golgotha is an elaboration on the symbol of the Cross, and is especially common in Orthodox monasticism. The meaning of the text is as follows (from top to bottom):
The King of Glory
Jesus Christ Conquers
Honored Trophy, the Dread of Demons
a Flow of Tears, more Eloquent than Orators
Christ Gives Grace to Christians
the Tasting of the Tree Brought Death
through the Tree of the Cross we have Found Life
the Discovery of Helen has Uncovered Eden
the Light of Christ Illumines All
the Vision of God, a Divine Wonder
Demons Dread the Sign of the Cross
the Tree of Life
the Place of the Skull has Become Paradise
With the Cross are the spear, which stabbed Christ's side, and the sponge, which was used to offer Him vinegar. The three steps and the skull represent the mountain of Golgotha, which means "the place of the skull."
You can choose Greek or English inscriptions, or if you prefer, you can choose just the Cross, without any text. The plaque is 6x12 inches.
