Offa, the strongest of the Saxon kings, minted high-quality silver pennies. He traded woolen coats for lava grindstones with Emperor Charlemagne, who used a silver denarius coin. There were 12 denarii to the solidus and 20 soldi to the pound of silver. These denominations were taken by England as 12 pennies to the shilling and 20 shillings to the pound. The pound sign, an "L" with a hash mark derived from the word Libra, which meant weighing scales. Everyone in the village went to church on Sunday and brought gifts such as grain to the priest. Later, contributions in the form of money became customary, and then expected. They were called "tithes" and were spent for church repair, the clergy, and poor and needy laborers. Local custom determined the amount. There was also church-scot: a payment to the clergy in lieu of the first fruits of the land. The priest was the chaplain of a landlord and his parish was coextensive with that landlord's holding and could include one to several villages. The priest and other men who helped him, lived in the church building. Some churches had lead roofs and iron hinges, latches, and locks on their doors. The land underneath had been given to the church by former kings and persons who wanted the church to say prayers to help their souls go from purgatory to heaven and who also selected the first priest. The priest conducted Christianized Easter ceremonies in the spring and (Christ's mass) ceremonies in winter in place of the pagan Yuletide festivities. Burning incense took the place of pagan burnt animal offerings, which were accompanied by incense to disguise the odor of burning flesh. Holy water replaced haunted wells and streams. Christian incantations replaced sorcerer's spells. Nuns assisted priests in celebrating mass and administering the sacraments. They alone consecrated new nuns. Vestry meetings were community meetings held for church purposes. The people said their prayers in English, and the priest conducted the services in English. A person joined his hands in prayer as if to offer them for binding together in submission. The church baptized babies and officiated or gave blessings at marriage ceremonies. It also said prayers for the dying, gave them funerals, and buried them. There were burial service fees, candle dues, and plough alms. A piece of stone with the dead person's name marked his grave. It was thought that putting the name on the grave would assist identification of that person for being taken to heaven. The church heard the last wish or will of the person dying concerning who he wanted to have his property. The church taught that it was not necessary to bury possessions with the deceased. The church taught boys and girls.
