In a procès of 1638, one of those interrogated, a nun named Martha Tondu, stated that at Reneval and the neighbouring villages "the peasants are on the look out, and if alarmed, retire and conceal their cattle in ditches and quarries, without abandoning their houses or neglecting their agricultural work."

Some, accordingly, of these subterranean refuges are of comparatively late date; but this does not apply to all. At every period of danger, instinctively the peasants would take advantage of the nature of the chalk to form in it suitable hiding-places, and although some of the finds in these labyrinths are of recent date, others go back to the Gallo-Roman period. In the Arras and Cambrai Chronicle of Balderic (1051), we are told that in the fifth century in those parts a persecution of the Christians occurred, on the invasion of the barbarians, and that the priests celebrated the Divine Mysteries in secret hiding-places. "Many," he adds, "were suffocated in caves and in subterranean passages."

There is, in fact, evidence both from archaeology and from history that these refuges were taken advantage of, and doubtless extended from a remote antiquity down to the eighteenth century.

It was not against the foreign foe only that the peasants excavated their underground retreats. Froissart paints the chivalry of his time in the brightest colours, and only here and there by a few touches lets us see what dark shadows set them off. Who paid for the gay accoutrements of the knights? Who were the real victims of the incessant wars? From whom came the ransom of King John and of the nobles taken at Creçy and Poitiers? From the peasant. The prisoners allowed to return on parole came to their territories to collect the sums demanded for their release, and the peasant had to find them. He had his cattle, his plough and tumbril. They were taken from him; no more corn was left him than enough to sow his field. He knew how he would be exploited, and he hid his precious grain that was to make bread for his wife and children. The seigneur endeavoured to extort from him the secret as to where it was concealed. He exposed the man's bare feet before the fire; he loaded him with chains. But the peasant bore fire and iron rather than reveal the hiding-place. Here is Michelet's account of the seigneur in the first half of the fifteenth century. "The seigneur only revisited his lands at the head of his soldiery to extort money by violence. He came down on them as a storm of hail. All hid at his approach. Throughout his lands alarm resounded —it was a sauve-qui-peut. The seigneur is no longer a true seigneur; he is a rude captain, a barbarian, hardly even a Christian. Écorcheur is the true name for such, ruining what was already ruined, snatching the shirt off the back of him who had one; if he had but his skin, of that he was flayed. It would be a mistake to suppose that it was only the captains of the écorcheurs—the bastards, the seigneurs without a seigneurie, who showed themselves so ferocious. The grandees, the princes in these hideous wars, had acquired a strange taste for blood. What can one say when one sees Jean de Ligny, of the house of Luxembourg, exercise his nephew, the Count of Saint-Pol, a child of fifteen, in massacring those who fled? They treated their kinsfolk in the same manner as their enemies. For safety—better be a foe than a relation. The Count d'Harcourt kept his father prisoner all his life. The Countess of Foix poisoned her sister; the Sire de Gial his wife. The Duke of Brittany made his brother die of starvation, and that publicly; passers-by heard with a shudder the lamentable voice pleading piteously for a little bread. One evening, the 10th of January, the Count Adolphus of Gueldres dragged his old father out of bed, drew him on foot, unshod, through the snow for five leagues to cast him finally into a moat. It was the same in all the great families of the period—in those of the Low Countries, in those of Bar, Verdun, Armagnac, &c. The English had gone, but France was exterminating herself. The terrible miseries of the time find expression, feeble as yet, in the 'Complaint of the poor Commoner; and of the poor Labourers.' It comprises a mixture of lamentations and threats; the starving wretches warn the Church, the King, the Burgesses, the Merchants, the Seigneurs above all, that 'fire is drawing nigh to their hostels.' They appeal to the king for help. But what could Charles VII. do? How impose respect and obedience on so many daring men? Where could he find the means to repress these flayers of the country, these terrible little kings of castles? They were his own captains. It was with their aid that he made war against the English." [Footnote: Mist, de France, v. p. 184 et seq.]

Thus, the subterranean refuges that had served at one time as hiding- places against Saracens, Normans, English, became places of retreat for the wretched people against their own masters. They no longer carried their goods into the souterrains under the castles, but into refuges contrived by themselves in the depths of forests, known only to themselves; hidden, above all, from their seigneurs.

The peasantry might have said then, what was said long after by Voltaire: "Il faut être dans ce monde enclume ou marteau; j'étais né enclume." Voltaire, however, speedily became a hammer, and after 1789 the Tiers État also became a hammer, and the Noblesse the anvil.

In Iceland there were underground retreats, as we learn from the same Saga that tells us of those in Aquitaine. Orvar Odd found a king's daughter concealed in one. So, also, a very large one in Ireland is spoken of in the Landnama Bok. In England we have, both in Essex and in Kent, subterranean passages and chambers very similar to those described in Picardy and in Aquitaine. These also are excavated in the chalk. They are the so-called Dene Holes, of which there are many in Darenth Wood and near Chislehurst, and they have given occasion to a lively controversy. Some have supposed them to be retreats of the Druids, some that they were places of refuge during the invasions of the Saxons first, and then of the Danes, and others again contend that they were merely quarries for the excavation of chalk to burn into lime.

Here is an account of the Dene Hole at Chislehurst by Mr. W. J. Nichols. [Footnote: Nichols (W. J.), "The Chislehurst Caves," Journal of the Archaeological Association, Dec. 1903.] "At the foot of the hill is a gap, which is the present entrance to the caves. A guide meets us here, who, unlocking a door, and switching on the electric light, introduces the visitor to a gallery or tunnel, about 150 feet long, 10 feet to 12 feet high, and with a width of 12 feet to 15 feet, narrowing to about 7 feet at the roof. This, and the galleries so far explored, have been cut through the chalk bed, at a depth of about 6 feet below the Thanet sand which covers it. At the end of the gallery, extending both right and left, are passages of like character. These again open into others so numerous that the visitor is fairly bewildered, and loses all idea of the direction in which he is travelling. The effect of the coloured electric lamps on the old chalk walling is remarkably beautiful. Proceeding on our way we get beyond the range of the electric lamps. Here candles or hand-lamps are lighted; and we pass, in Cimmerian gloom, through a succession of galleries of various dimensions, some of which, being only 4 feet wide and 5 feet high, are possibly of earlier construction than those already described. There is one gallery of the last-mentioned height and width 63 feet long, with several sharp turns which formerly terminated in a chamber about 12 feet high and 10 feet wide, and a like length, and near it is a seat cut into an angle of the walling. At no great distance from this chamber and near a Dene-hole shaft is a short gallery, at the end of which is a shaft originally level with the flooring, but now bricked round and further protected by an iron cover. On removing the cover and lowering a lamp, a well of excellent workmanship is discovered. Owing to the quantity of material thrown down from time to time by explorers, its present depth is no more than 43 feet. Further progress is made, and presently we notice a streak of daylight some distance ahead; here we find that we have reached the foot of a shaft 85 feet deep, which, though now partly covered in, had its mouth in what is at the present time the garden of a modern villa."

There are numerous other Dene Holes or Danes' Pits at East Tilbury, Crayford, and Little Thurrock. As to the theory that they were places of Druidical worship, we may dismiss it as not deserving serious consideration.

At East Tilbury the entrance to the Danes' pit is from above, by narrow passages that widen and communicate with several apartments, all of regular forms. One of these pits consists of a shaft descending to chambers arranged like a sixfoiled flower. The shaft is 3 feet in diameter and 85 feet deep. This may be likened to one at Doué-la- Fontaine (Maine et Loire), where a descent is made under a private house into an area from which radiate on all sides chambers, some of which contain tombs.
