Space would fail us in enumerating the many lesser articles of interest discovered in Lincoln. Seven tessellated pavements have been found, all in the upper city; a perfect Roman altar, with inscription, came to light in 1884 on the site of St. Swithin’s Tower; and at least six sepulchral slabs have been unearthed, three of which were in memory of soldiers of the Ninth (Spanish) Legion—perhaps an indication that to this legion, which is not mentioned after Trajan’s reign, lands were assigned at the foundation of the colony. Traces of interments have been found bordering the roads on the north, east, and south of the city; those beyond the east gate seem to be the most numerous, and in one case the remains were enclosed in a large burial-chamber. In the immediate neighbourhood of the city were villas of some size. At Canwick Church there is a tessellated pavement, two feet below the floor-level, extending the whole length of the nave; and at Greetwell, a mile and a half to the east, a substantial residence was discovered, with many rooms and corridors, and with pavements of artistic design.

In the three centuries between Ptolemy, who first mentions the city, and the abandonment of Britain by Rome, Lindum is named but once—in the Antonine Itinerary. But it seems likely that Adelfius, one of the three British prelates at the Council of Arles, was its bishop in 314.[16]

With regard to the roads radiating from Lindum, it will be convenient to deal first with those to the north. From Newport Gate, Ermine Street continues to the Humber for thirty miles in a direct line—absolutely straight, indeed, for five-sixths of the distance. Mr. Codrington assumes without reason that this road was earlier than that already mentioned, which crossed the Trent and passed by way of Doncaster and Castleford to York.[17] Present appearances certainly justify his view, for the latter road now seems merely a branch of the former. But this may not always have been the case. Originally the first four miles may have been nearer the edge of the high ground through Burton and North Carlton into Tillbridge Lane; but when the direct Ermine Street was constructed this portion would not be repaired, and therefore would be completely disused, as the increase in distance by the new road would be trifling. It is a curious fact that the only section of Ermine Street between London and the Humber included in the Antonine Itinerary is that between Lincoln and Godmanchester; the route from Lincoln to York in two Iters (V. and VIII.) is by the Doncaster road, which is longer than Ermine Street by several miles if York were the objective, but which rather points directly to Isurium—supposed by some to have been the Brigantian capital.[18] The presumption should surely be that the shorter route, which involved the crossing of a broad estuary, would be a later construction of more settled times. In the parish of Scampton, adjoining the Doncaster road, and about a mile and a half north-west of the point where it branches from Ermine Street, was discovered in 1795 a large Roman villa, with forty rooms and thirteen tessellated pavements—one of a very beautiful design. The whole building covered a space 70 yards square, and included two courtyards, thus differing somewhat in plan from the great villas of the south-west.

Ermine Street from Lincoln to the Humber is one of the finest of Roman highways—clearly traceable to-day for almost the whole distance. In a stretch of thirty miles there must have been a middle station, which was certainly in Hibaldstow; but since remains have been found here on both sides of the great “Way,” its exact site is uncertain. At the farm of Gainsthorpe, about 200 yards to the west, is a remarkable cluster of ruined habitations, which has never been properly explored: excavation here, and in a large camp a little to the north on the east side of Ermine Street, promises to yield fruitful results. From this point there would naturally be a by-road to Caistor, ten miles due east across the Ancholme valley, but no traces of it are on record. A pavement has been found in Hibaldstow, and two more at Storton in Scawby—the next parish to the north. The line of the road passes through Broughton, three miles west of Brigg, where various remains have been discovered; and the country round it, as it approaches the Humber, abounded in rural residences of the better class. At Roxby, a mile and a half to the west, a good pavement was found in 1709; and about forty years later, three more of very superior design were discovered below the Cliff House in Winterton, one of which had a bust of Ceres in the centre. A fourth near the same spot, with a figure of Apollo, was unearthed in 1797; and in a garden at Horkstow, more than three miles east of this site, was found a pavement with three compartments, in which are depicted the Fates, Orpheus playing the lyre to the animals, and a chariot race. Among the remains found at Winterton are many coins, spear-heads, a brass eagle, and a potter’s kiln; while another kiln was found at Santon in Appleby, a few miles to the south. This district—as also the chalk ridges of the Eastern Wolds—seems to have been favourable for the manufacture of the coarse grey and stone-coloured pottery, so common on Roman sites in the county. The Ermine Street ended at a promontory overlooking the Humber in the parish of Winteringham, below which was an ancient haven called Flashmire, now silted up. This point is a little east of the Roman “station” of Brough on the opposite shore, so that boats could make the crossing of under two miles with the inflowing tide. In the dry summer of 1826, when the water was low, a paved causeway or jetty—like that leading to the Trent at Littleborough—was exposed on both the Lincolnshire and Yorkshire banks. Stukeley says that, when the “station” at Winteringham was ploughed up in 1700, extensive remains were found—as of stone foundations, pavements, and streets made of gravel and sea-sand. About four miles south-west of this point, and half-way to the Roman Camp at Barton, lies South Ferriby. Here is an ancient well-spring, near which at various times interesting articles have been found—some, perhaps, votive offerings to the local goddess of the spring. These objects, now principally in the Hull Museum, include cinerary urns of all kinds, fireplaces, coins, and a remarkable collection of bronze fibulæ—many harp-shaped (two with the Gaulish maker’s name, “Aucissa”) and others flat, with the disc in the shape of a fish or sandal. From Winteringham there may have been a branch-way to Barton—seven miles to the east. At Alkborough, about four miles westward, there is a strong camp, about one hundred yards square, overlooking the junction of the Trent and the Humber. Its Roman origin is disputed, and the area has never been carefully excavated.

Returning once more to Lincoln, we find at least one road leaving the east gate of the city, which is nearly identical with the present Wragby road. This was in line with the Foss Way, but was of much less importance. At Claybridge, about seven miles from Lincoln, a by-way branches off south-eastwards to the fort at Horncastle; while another, called Horncastle Lane, which is probably Roman, bends westward to the junction of Ermine Street and Tillbridge Lane. The main way continues north-eastward through Ludford and Ludborough to the coast, where it ends at some remains of saltworks in the parish of Grainthorpe. Its easterly part used to be known as “Salters’ Lane,” and it crosses the “High Street” from Horncastle to Caistor at Ludford. It is possible that this route and a branch-way from Ermine Street were the only roads from Lincoln to Caistor; at least no traces of a road, or even of Roman remains, are known to me on the direct line between the east gate and Caistor.

No road of any importance seems to have left Lincoln by the west gate; and the reason for this is to be found in the physical features of the neighbourhood at the time of the Roman occupation. The part of Lincolnshire north of the Witham is still called “Lindsey”—a name which indicates by its final syllable that, when it was given, the district was practically surrounded by water. On all sides but the south it is so to this day—viz. by the sea on the east, by the Humber on the north, and by the Trent on the west. In the Roman period—and indeed for many centuries after—the Witham was tidal as far as the narrow “Gap” between Lincoln and the opposite high land of Kesteven. Geologists tell us that this “Gap,” now intersected by the Witham, was in pre-glacial ages scooped out by the Trent, the course of which from Newark was then north-east instead of north; and that after that river had been “captured” by the Humber (i.e. diverted into its present bed by the opening of a longitudinal valley from the north) it would always tend to revert to its original course in time of flood. The result of this constant flooding was the formation of a large mere, extending from the western end of the Gap as far north as Brampton, beyond which the east bank of the Trent was too high for the water to escape. The first syllable of Lindum no doubt represents the Celtic word, which was applied to this large sheet of water. Faint remains of it can still be seen in the small pool of Brayford—just below the south gate of the lower city. The flood-water came through five openings in a low range of sandhills between Spaldford and Brampton; and the first work of the Roman engineers was to build banks across these openings, and so shut out the water of the Trent. The southernmost opening at Spaldford—the most dangerous because the highest up the valley—was closed by a bank from 12 to 15 feet high and a mile and a half in length.

Through the marsh which was left when the water disappeared the Romans constructed a navigable canal, now called the Fossdyke, between the Witham and the Trent. Its original course at the western end was, according to Stukeley, more direct than at present—joining the Trent not, as now, at Torksey, but about two miles farther south. From its bed was dredged up in 1774 a small bronze statue of Mars, with a Latin inscription. At Lincoln itself the Sincil Dyke, a drain of the “Slaker” type—to ease off the water in time of flood—was constructed connecting the upper and lower ends of the loop which is made by the Witham in order to pass through the Gap. These operations certainly took place at a very early period of the Roman occupation of Lincoln. For until they were made effective, it would be impossible to lay the line of the Foss Way between Lincoln and Leicester; and we know from a milestone discovered on that road three miles north of Leicester, and dedicated to Hadrian in A.D. 120 (when he was in Britain), that the eastern part of the Foss Way—doubtless the earliest made in order to connect Lincoln with Watling Street—was being laid down in the first quarter of the second century. In the valley below Lincoln, Ermine Street and the Foss Way, which were united for the crossing, traversed the marshes of the Gap on a pile-foundation.

But the chief anxiety of a Roman general, who would secure the submission or tranquillity of this part of Britain, must have been the condition of the Fen district along the lower reaches of the Witham, and beyond it to the south. If the Coritani had to be subdued by force of arms, as we have supposed, their subjugation must have been a long business. Moreover, the Romans were experienced agriculturists, and must have guessed the value of the rich fenland east and south-east of their colony. On that side there was doubtless an even larger mere than on the west—caused partly by the flood-water which had overflowed the Gap, partly by streams from the high land of Kesteven; and this sheet of water must have risen considerably in height during the spring-tides. In this mere for many miles the stream of the Witham must have been barely discernible. Below it the district of Holland was a vast morass, liable to inundation both by the sea and by the rivers—then of much larger volume than now—which fell into the Wash. It is not likely that this district was largely settled by the natives before the Romans came, and the British antiquities found are few; but it was a natural refuge for the disaffected—as was shown later during the Danish and Norman invasions. Herodian says[19] of the campaign in Scotland in 209 that the Emperor Severus made passage for his troops over the fens, where, “from the frequent overflowing of the ocean, the inhabitants will swim and walk, though up to their middle in water.”

The engineering skill needed to cope with this situation was very great; and if proof be required that the Romans exercised it, the answer is sufficient that neither before nor for a thousand years after this period was there a central organisation strong enough to carry out such operations. The work had to be of two kinds—draining, to carry off the flood-water and void the rainfall coming from the high land, and embanking, to shut out the sea. In the former the Romans acted upon sound principles, which were often neglected in after times. They used the natural rivers as arterial drains, and led the subsidiary drains into them. History records that they executed similar works in other parts of the Empire. The Pontine marshes and the Lombard valley of the Po were drained under the Republic. The Emperors Claudius and Hadrian began and completed a canal between the Fucine Lake and the Liris. In the Low Countries, Drusus, in 12 B.C., drew a channel connecting Lake Flevo (Zuyder Zee) and the Rhine; and in A.D. 47 Corbulo made a canal, twenty-three miles in length, between the Rhine and the Meuse. Eleven years later a project for uniting the Saone and the Moselle, and thus completing a waterway from the Mediterranean to the North Sea, was only not attempted from fear of the jealousy of Nero. If a full account was ever written of the Roman settlement of Britain, the operations now to be described must have filled a large place in it.

The present channel of the Witham from Lincoln to Boston is much too straight to have ever been the course of a natural stream. From Chapel Hill just below Dogdyke, where there was a tidal creek, the river was canalised to Boston as late as 1761; but there is no record in historical times of such an operation in the twenty miles from Lincoln to Dogdyke. In order to drain the lower mere described above, a channel was cut along the high land for that distance, and the upper waters of the river directed into it. In very early (perhaps in Roman) times there was another branch of the Witham due east from Dogdyke through the upper fen to Wainfleet, where it received the Steeping, and thence into the sea near Gibraltar Point. Very probably it was the draining of the district near Lincoln which hastened the silting up of this ancient channel. But at no time can it have been, as some have fancied,[20] the principal outfall of the river, for it is much farther from the sea, and could not have been tidal, like the other, for the whole distance.
