Let us take these several points in order.
1. Evidence of Situation.
The river Thames, which narrowed at London Bridge, began to widen out west of the mouth of the stream called the Fleet. There was a cliff or rising bank along the Strand, which confined the stream on its north bank as far as Charing. At this village the course of the river turned south, and, after half a mile, southwest. Here it formerly broadened into a vast marsh or lagoon, quite shallow to east and west, in parts only covered with water at high tide, and in parts rising above even the highest tides. This great marsh covered all the land known later as St. James’s Park, Tothill Fields, the Five Fields, Victoria, Earl’s Court, and part of Chelsea: on the other bank the marsh extended from Rotherhithe over Bermondsey, Southwark, Lambeth, Vauxhall, and part of Battersea. The places which here and there rose above the reach of flood were called islands; Bermond’s-ea—the Isle of Bermond; Chels-ea—the Isle of Shingle (Chesil); Thorn-ea—the Isle of Bramble; Batters-ea—the Isle of Peter. You may find little islands (eyots—aits) just like these higher up the river, such as Monkey Island, Eelpie Island, and so many others. No doubt, in very remote times, these little river islets were secluded places indeed; if any people lived upon them, they lived like the lake dwellers of Glastonbury, each family in its cottage planted down in the sedge and mud of the foreshore, resting on piles, with its floor of hard clay pressed down on timber, its walls of clay and wattle, its roof of rushes, its boat floating before the door. They trapped elk and deer and boar, they shot the wild fowl with their slings, they caught the salmon that swarmed in the river. Thorney, then, the site of the future abbey, the Isle of Bramble, was an islet entirely surrounded by the waters of a broad and shallow river. It was so broad that the backwater extended as far as the present site of Buckingham Palace. It was so shallow that at low tide a man could wade across from the rising ground of the west to the island, and from the island to the opposite shore, where is now St. Thomas’s Hospital.
This is the evidence of the natural situation, and so far all would be agreed.
2. Evidence of Excavation.
SARCOPHAGUS OF VALERIUS AMANDINUS.
The kindly earth covers up and preserves many precious secrets,—“underground,” says Rabelais, “are all great treasures and wonderful things,”—to be revealed at some fitting time, when men’s minds shall be prepared to receive them. The earth preserves, for instance, the history of the ancient world—witness the revelations in our own time of the cuneiform tablets and the vast extension of the historic age: the arts of the ancient world, and their houses, and their manner of life—witness the revelations of Pompeii. Applied to Thorney, excavation has shown—what we certainly never could have known otherwise—that here, of all places in the world, in this little secluded islet in the midst of marshes (the most unlikely spot, one would think, in the whole of Britannia), there was a Roman station, and one of considerable importance. The first hint of this fact was suggested when there was dug up in the North Green of the Abbey, in the year 1869, a fine Roman sarcophagus inscribed with the name of Valerius Amandinus. The lid has a cross upon it, from which it has been conjectured that the sarcophagus was used twice, its second occupant having been a Christian. What reason, however, is there for supposing that Valerius Amandinus himself was not a Christian?—for, at least a century before the withdrawing of the Legions, Roman Britain was wholly Christian. For more than two centuries Christians had been numerous. During the fourth century the country was covered with monastic foundations for monks and nuns. Christian or not, there stands the sarcophagus of Valerius Amandinus, for all the world to see, at the entrance of the Chapter-house; and why a Roman cemetery should be established in Thorney no one could guess. But some ten years ago there was a second discovery. In digging a grave under the pavement of the nave, there was found a mosaic floor in very fair condition. This must have belonged to a Roman villa. But, if one villa, why not more? The question has been settled by the discovery, of late years, wherever the ground on Thorney has been opened, of Roman bricks and fragments of Roman buildings. It is now impossible to doubt the existence here of a Roman station.
That is, so far, the (unfinished) evidence of excavation.
