Silchester was a very busy place. There were dye works there, as the excavations show; hence there must have been some weaving, and therefore a large resident population. Throngs of travellers used to pass through it, and carts and baggage animals bore through its streets the merchandise from London, which passed to the cities and villas so plentifully scattered in western Britain. By far the most important of the discoveries made in Roman Britain is the little church which stood just outside the forum. It is very similar in form to the early churches in Italy and other parts of the Roman Empire, and is of the basilican type. The orientation is different from that used after the reign of Constantine, the altar being at the west end. The churches of S. Peter and S. Paul at Rome had the same arrangement; and the priest evidently stood behind the altar facing the congregation and looking towards the east at the time of the celebration of the Holy Communion. There is an apse at the west end, and the building is divided by two rows of columns into a nave and two aisles. The nave had probably an ambon, or reading-desk, and was mainly used by the clergy, the aisles being for the use of the men and women separately. A vestry stood at the western end of the north aisle. Across the eastern end was the narthex, or porch, where the catechumens stood and watched the service through the three open doors. Outside the narthex was the atrium, an open court, having in the centre the remains of the labrum, or laver, where the people washed their hands and faces before entering the church. We are reminded of a sermon by S. Chrysostom, who upbraided his congregation, asking them what was the use of their washing their hands if they did not at the same time cleanse their hearts by repentance. This interesting memorial of early Christianity was probably erected soon after the Emperor Constantine's Edict of Toleration issued in 313 A.D. But not only at Silchester and at other places, once the great centres of the Roman population, do we find Roman remains. In addition to the stations, camps, and towns, there were the villas of the rich Roman citizens or Gaulish merchants on the sunny slopes of many a hillside. Although hundreds of the remains of these noble houses have been discovered, there are still many to be explored.
