Sicut cervus is a motet for four voices by Giovanni Pierluigi da Palestrina. It sets the beginning of Psalm 42, Psalmus XLI in the Latin version of the Psalterium Romanum rather than the Vulgate Bible. The incipit is "Sicut cervus desiderat ad fontes" followed by a second part "Sitivit anima mea". It has become one of Palestrina's most popular motets, regarded as a model of Renaissance polyphony, expressing spiritual yearning.
