The correct term for images of a person in prayer with outstretched arms is Orant Figure.
In Christian art, an orant is a person shown in a praying stance with outstretched arms. The orant theme is notably significant in Early Christian art (c. 2nd–6th century), especially in the murals and graffiti that covered Roman tombs from the 2nd century onward.
It appears that the similar posture to that of orant figure of prayer was adopted by the early Christians. The most often depicted narrative topics of the catacombs, figures from Old Testament episodes of divine deliverance of the devout, are displayed in the orant stance. The orant has been understood as a representation of faith or of the church itself in specific settings where it is not associated with any one person.
