Following Communion, the Aër is placed, still folded, on the Diskos, together with the Spear, Spoon and Asterisk and little veils, and all are taken back to the Prothesis by the deacon.
During the Prothesis (Liturgy of Preparation, at which the wine and bread are prepared on the Table of Oblation), the priest will bless each prosphoron as he takes it up to remove particles and place them on the diskos (paten).
When a priest is ordained, a portion of the Lamb will be placed on a small diskos and given to him, as a sign of the Sacred Mysteries which are being entrusted to his care.
