Also spelt Matins in some places. This service (like Evensong) was created by Thomas Cranmer from the sevenfold monastic cycle of prayer. Although less common these days, it still takes place in most British Cathedrals before or after the Eucharist on a Sunday morning.
Mattins and Evensong are in the Book of Common Prayer - the present edition of dates to 1662, but it was first compiled in 1549 by Thomas Cranmer. It was comprehensively revised in 1552 to make it more Protestant in spirit, and then again in 1559 as part of the Elizabethan Settlement to make it somewhat less Protestant. The 1559 Prayer Book was used until 1645, when it was abolished by the Long Parliament. It was reinstated after the restoration of King Charles II. It continues to be used today, alongside the new service book, Common Worship. Anglican churches in other countries, such as the United States, have their own versions

 *Introit (hymn or anthem)
