Friar Stone, it is to be feared, is only one of a long procession of tortured ghosts who might meet us where the children play on the Dane John. But it was not always the place of execution, it came to be a coign of vantage from which the orthodox (for the time being) could comfortably view, not without lunch-baskets, what went on in Martyr's Field, now marked with an obelisk a little to the south-west of the mound. Here were forty, men, women, and children, "brent" or burnt at the stake in the reign of Queen Mary for asserting what Friar Stone denied. Their names are carved in granite on the spot where they died, and the motto on the monument is: "Lest We Forget".
From the Dane John we may return along the earthen rampart by the city wall to St. George's Street, and ask our way to St. Martin's, believed by competent enquirers to be the oldest church not only in England, but in Europe. It certainly existed in the sixth century, when Queen Bertha came to its services through the postern still known as Quenengate. Bede, the father of English history and the most learned man of the seventh century, says that there was a Christian church here during the Roman occupation. As the Romans left in 410, this gives a record of fifteen centuries of worship on this site. Here King Ethelbert was baptized by Augustine, and a representation of this event graven on an ancient seal gives a font much resembling the one still in use.
The walls, of course, have been patched and repaired many times, but are, especially in the chancel, full of Roman bricks and Saxon workmanship. There are indications that some of the courses were actually laid by Roman hands; and, if this be so, imagination may carry us back far earlier than Augustine, to the legend that Joseph of Arimathea brought the Gospel to Britain within a generation of the death of Our Lord.
On our way back to the town, if we step inside the Infirmary grounds, we shall see the ruins of St. Pancras, built, it is said, by Augustine on the foundations of an "Idol-temple" where Ethelbert worshipped before his conversion. Roman bricks abound, Roman pillars are built into the wall, and there are still the remains of an altar in a tiny chapel where probably Augustine officiated.
