The Apolytikion or Dismissal Hymn is a troparion said or sung at Orthodox Christian worship services. The apolytikion summarizes the feast being celebrated that day. It is chanted at Vespers, Matins and the Divine Liturgy; and it is read at each of the Little Hours. The name derives from the fact that it is chanted for the first time before the dismissal of the first service of the liturgical day, Vespers, the liturgical day beginning at sunset in the Orthodox Church.
