“O iubar, nostrae specimen salutis” is a rare Renaissance polyphonic hymn dedicated to the Holy Shroud of Turin, published in Willaert’s Hymnorum musica in Venice (1542).
Composed around 1542, likely honoring the relic after a 1532 fire, it is a roughly 11-minute, 6-voice work noted for complex, varied, and expressive polyphony.
