Or, an essay on an ancient prophetical inscription, in monkish rhyme, lately discovered near Lynn, in Norfolk. By Probus Britannicus [17]. In Norfolk, near the town of Lynn, in a field, which an ancient tradition of the country affirms to have been once a deep lake, or meer, and which appears, from authentick records, to have been called, about two hundred years ago, _Palus_, or the marsh, was discovered, not long since, a large square stone, which is found, upon an exact inspection, to be a kind of coarse marble of a substance not firm enough to admit of being polished, yet harder than our common quarries afford, and not easily susceptible of injuries from weather or outward accidents. It was brought to light by a farmer, who, observing his plough obstructed by something, through which the share could not make its way, ordered his servants to remove it. This was not effected without some difficulty, the stone being three feet four inches deep, and four feet square in the superficies; and, consequently, of a weight not easily manageable. However, by the application of levers, it was, at length, raised, and conveyed to a corner of the field, where it lay, for some months, entirely unregarded; nor, perhaps, had we ever been made acquainted with this venerable relick of antiquity, had not our good fortune been greater than our curiosity. A gentleman, well known to the learned world, and distinguished by the patronage of the Maecenas of Norfolk, whose name, was I permitted to mention it, would excite the attention of my reader, and add no small authority to my conjectures, observing, as he was walking that way, that the clouds began to gather, and threaten him with a shower, had recourse, for shelter, to the trees under which this stone happened to lie, and sat down upon it, in expectation of fair weather. At length he began to amuse himself, in his confinement, by clearing the earth from his seat with the point of his cane; and had continued this employment some time, when he observed several traces of letters, antique and irregular, which, by being very deeply engraven, were still easily distinguishable. This discovery so far raised his curiosity, that, going home immediately, he procured an instrument proper for cutting out the clay, that filled up the spaces of the letters; and, with very little labour, made the inscription legible, which is here exhibited to the publick: POST-GENITIS.
