The tenth-century Benedictional of St. Æthelwold, bishop of Winchester, has a formula used for blessing the candles. Candlemas did become important enough to find its way into the secular calendar. It was the traditional day to remove the cattle from the hay meadows, and from the field that was to be ploughed and sown that spring. References to it are common in later medieval and early Modern literature; Shakespeare's "Twelfth Night" is recorded as having its first performance on Candlemas Day 1602. It remains one of the Scottish quarter days, at which debts are paid and law courts are in session.
