Paul Gerhardt wrote a German version which is known by its incipit, "O Haupt voll Blut und Wunden". </P> <P> The hymn is based on a long medieval Latin poem, Salve mundi salutare, with stanzas addressing the various parts of Christ's body hanging on the Cross . The last part of the poem, from which the hymn is taken, is addressed to Christ's head, and begins "Salve caput cruentatum ." The poem is often attributed to Bernard of Clairvaux (1091 - 1153), but is now attributed to the Medieval poet Arnulf of Leuven (died 1250). The seven cantos were used for the text of Dieterich Buxtehude's Membra Jesu Nostri addressing the various members of the crucified body </P>
