CAP. XXXIII. How it became overflowed by the Sea.
GRanting therefore, that this Country, though lying flat and low, was not originally annoyed with the inundations of the Ocean, or any stop of the fresh waters, which might by o∣verflowing and drowning make it fenny; and considering the situation thereof to be such, as that it is bounded on all parts by the high lands, in the form of an Horshoo, excepting towards the Sea, from that point of land, about Hunstan∣ton in Norfolk, to Wynthorpe in Lin∣colnshire, which maketh it much like unto a Bay; I am now to demon∣strate by what means it came to passe, that the Ocean, at first, brake into it with such violence, as that the woods then standing throughout the same, be∣came turned up by the roots; and so great a proportion of silt brought in, as not only for divers miles, next towards the Sea, did cover the ground to an extraor∣dinary depth (as I shall plainly shew a∣non) but even to the remotest parts on the verge of the High lands, as is appa∣rent from that discovery made of late years, at the skirt of Conington down in Huntendonshire; where, upon ma∣king of a pool, by the famous Sir Robert Cotton Baronet, he found the skeliton of a large Sea-fish (neer xx foot long, as was then conjectured) lying in perfect silt, above six foot below the superficies of the ground, and as much above the present Levell of the Fen; which, by so long a continuance in that kind of earth, was petrified, as is evident from divers of the bones, both of the back and other parts, which are still preserved by Sir Thomas Cotton Baronet, his worthy son, amongst other extraordinary rari∣ties, that were collected by that learned person.
But when and by what means that vi∣olent breach and inundation of the Sea was first made into this Country, I am not able positively to affirm: therefore I must take leave to deliver my conje∣cture therein, from the most rational probabilities: VVhich is, that it was by some great Earthquake, for, that such dreadful accidents have occasio∣ned the like, we have unquestionable te∣stimony.
Coss. Valentiniano & Valente (saith the tripartite a 1.1 History) terrae motus factus multas diruit Civitates,* 1.2 sed etiam mare ter∣minos proprios mutavit; & in quibusdam locis in tantum ibi fluxit, ut loca quae pri∣dem ambulari poterant, remigarentur; ab aliis verò locis tantum recessit, ut arida tel∣lus inveniretur. In the time of the Consul∣ship of Valentinian and Valens, there was an Earthquake, which not only overthrew divers Cities, but altred the very bounds of the Sea; which so flowed in some parts, that men might sayl in those places, where before they did walk; and forsook other, that they became dry land. The like relation of the same Earthquake, but somewhat more largely, doth Ammianus b 1.3 Marcelli∣nus make. And to the like purpose also is that of Ovid c 1.4.
