From the 4th century, there existed in certain places and at sporadic intervals a feast date to commemorate all Christian martyrs. It was held on 13 May in Edessa, the Sunday after Pentecost in Antioch, and the Friday after Easter by the Syrians. During the 5th century, St. Maximus of Turin preached annually on the Sunday after Pentecost in honor of all martyrs in what is today Northern Italy. The Comes of Würzburg, the earliest existing ecclesiastical reading list, dating to the late 6th or early 7th century in what is today Germany, lists this the Sunday after Pentecost as "dominica in natale sanctorum" or "Sunday of the Nativity of the Saints". By this time, the commemoration had expanded to include all saints whether or not they were martyred.
