Though music in Divine service had always a place, yet the use of instrumental music seems not to have become general till the time of Thomas Aquinas, about 1250. And it is related that one Marinus Sanutus, who lived about 1290, was the first to introduce wind organs into churches, whence he was called Torcellus, which is the name for an organ in the Italian tongue. This instrument had long been known as a curiosity before that time, and one was sent by the Greek Emperor about 766 to King Pepin. The use of bells as a mode of summoning worshippers to Divine service was soon thought of as a substitute for employing deacons or deaconesses to give private notice to each attendant. In Egypt the early Christians imitated the Jews by blowing a trumpet. In the early monastery set up by Paula at Jerusalem, one of the virgins was set apart to go round singing hallelujah. In the time of Bede, in the seventh century, bells began to be used as a mode of summoning to worship. And in 968 Pope John XIII. consecrated the great bell of the Lateran Church in Rome, calling it John. SEPARATION OF SEXES IN CHURCHES. The custom of separating the sexes in church had a very remote origin. John Gregorie, in his works (published in 1646), says: "There is a tradition that in the ark, so soon as ever the day began to break, Noah stood up towards the body of Adam and before the Lord, he and his sons, Shem, Ham, and Japhet. And Noah prayed and his sons; and the women answered from another part of the ark, 'Amen, Lord.' Whence you may note too (if the tradition be sound enough) the antiquity of that fit custom (obtaining still, especially in the Eastern parts) of the separation of the sexes, or the setting of women apart from the men in the houses of God. Which sure was matter of no slight concernment if it could not be neglected, no, not in the ark, in so great a straightness and distress of congregation." THE ANCIENT CHURCH PRAYING FOR THE DEAD.
