The Matins service for Monday through Wednesday of Holy Week is known as the Bridegroom Service or Bridegroom Prayer, because of their theme of Christ as the Bridegroom of the Church, a theme expressed in the troparion that is solemnly chanted near the beginning of the service. On these days, an icon of "Christ the Bridegroom" is placed on an analogion in the center of the temple, portraying Jesus wearing the purple robe of mockery and crowned with a crown of thorns (see Instruments of the Passion). The Matins Gospel read on this day is from the Gospel of Matthew ). The canon at Matins has only three odes in it (a "triode"), and was composed by St. Cosmas of Maiuma.
