Quicumque Christum quaeritis by Orlando de Lassus (SATB Chorus) The Vesper Hymn Quicumque Christum quaeritis is the twelfth and last poem in the Cathemerino of Prudentius, originally written in honour of the Epiphany. It is sung at both Matins and Second Vespers on the Feast of the Transfiguration (August 6, observed by modern Lutherans on the last Sunday before Lent). The same gospel is read on Lent II.
