At early dawn he sallied forth to perform his earliest duty of opening the church doors and ringing the day-bell. The ringing of bells seems to have been a fairly constant employment of the clerk, though in some churches this duty was mainly performed by the sexton, but the aid of the clerk was demanded whenever it was needed. According to the constitution of the parish clerks at Trinity Church, Coventry, made in 1462, he was ordered every day to open the church doors at 6 a.m., and deliver to the priest who sang the Trinity Mass a book and a chalice and vestment, and when Mass was finished to see that these goods of the church be deposited in safety in the vestry. He had to ring all the people in to Matins, together with his fellow-clerk, at every commemoration and feast of IX lessons, and see that the books were ready for the priest. Again for High Mass he rang and sang in the choir. At 3 p.m. he rang for Evensong, and sang the service in the south side of the choir, his assistant occupying the north side. On weekdays they sang the Psalms and responses antiphonally, and on Sundays and holy-days acted as _rectores chori_, each one beginning the verses of the Psalms for his own side. He had to be very careful that the books were all securely locked up in the vestry, and the church locked at a convenient hour, having searched the building to see lest any one was lying in any seat or corner. On Sundays and holidays he had to provide a clerk or "dekyn" to read the gospel at High Mass. The sweeping of the floor of the church, the cleaning of the leaden roofs, and sweeping away the snow from the gutters "leste they be stoppyd," also came under his care. The bells he also kept in order, examining the clappers and bawdricks and ropes, and reporting to the churchwardens if they required mending. His assistant had to grease the bells when necessary, and find the materials. He had to tend the lamp and to fetch oil and rychys (rushes), and fix banners on holidays, fold up the albs and vestments. On Saturdays and on the eve of saints' days he had to ring the noon-tide bell, and to ring the sanctus bell every Sunday and holy-day, and during processions.
