Tallis' Candidi facti sunt, is a responsory intended to be sung in honour of one or more Apostles, or an Evangelist, during Eastertide. Given that
- The Tudor monarchs took a close interest and usually participated in the royal household's religious observances for Feast days.
- That the only Apostles or Evangelists whose feasts can fall within Eastertide are St. Mark (25 April) and Ss. Philip and James (1 May).
Candidi facti sunt must have been written for a year when one or other of those feasts coincided with some important political or diplomatic (court) occasion. Like all of his Latin hymns and responsories it's essentially a setting of the original plainchant melody and reflects its plainchant origins in that its performance involves alternating plainchant and polyphony with the polyphonic sections quoting the chant that they replace.
