Arma Christi, or the Instruments of the Passion, are the objects associated with the Passion of Jesus Christ in Christian symbolism and art. They are seen as arms in the sense of heraldry, and also as the weapons Christ used to achieve his conquest over Satan. There is a group, at a maximum of about 20 items, which are frequently used in Christian art, especially in the Late Middle Ages. Typically they surround either a cross or a figure of Christ of the Man of Sorrows type, either placed around the composition, or held by angels.

Andachtsbilder is a German term often used in English in art history for Christian devotional images designed as aids for prayer or contemplation. The images "generally show holy figures extracted from a narrative context to form a highly focused, and often very emotionally powerful, vignette".
