In the Orthodox Church, the artophorion is a vessel in which the Eucharist is kept for the communion of the sick and the liturgy of the presanctified. It has the form of a church resting on the altar, or less commonly that of a dove hanging above the altar. Smaller artophoria are used to bring communion to the sick. Although the reservation of the Eucharist is attested as early as the 3rd century, pyxes made especially for that purpose do not appear until after the turn of the millennium.
