I shall give the reader a plain calculation of the number of people, that might commodiously be present at the solemn sports and diversions, made generally upon holy-days and great festivities of their gods. The people hereabouts told me, that once they executed a woman for petit-treason, in the middle of the _area_, by burning; which brought all the country round to the sight, and filled the whole place: they by a gross guess supposed there might be 10,000. But if we allow a foot and half for each person sitting, and the number of seats, as I have delineated it, 24; then one side of the building spread _in plano_ will form a conic _frustrum_ 440 feet long at top, 280 at bottom; taking the medium number 360, multiplying it by 24, it gives us 8640 feet; from which take off a fourth part, to reduce it to single places of a foot and half, there remain 6480 places on one half of the amphitheatre; double this for the other side, and you produce 12,960 single places for spectators upon the whole range of seats. For fear of exceeding the truth, I omit all that might occasionally stand on the terrace at top, the ascent up to it, and on the entrance. It would be vain to talk of the exact time, or the persons concerned in building this amphitheatre: but my friend Mr. Pownall of Lincoln, before spoken of, has a silver coin of Philippus, ploughed up in the very place. _imp. m. jul. philippus aug._ ℞ _lætit. fundat._ a Genius with a garland in his right, the helm of a ship in his left hand: the legend of the reverse, I must own, seems strongly to intimate he made or repaired this work, or that some solemn sports were here performed in his time; notwithstanding his melancholy and cynical nature, which Sext. Aurelius gives us an account of, or that he was a christian. He reigned about A. D. 240. yet I chuse to think it is of a higher date. Tacitus tells us, so early as the time of Agricola in Titus his reign, they began to introduce luxury among the Britons; for he exhorted them privately, and publicly assisted them, to build temples, places of public resort, and fine houses; and by degrees they came to those excitements to debauchery, portico’s, baths, and the like, of which we frequently find the ruins. Therefore we may suppose amphitheatres were not forgotton; and probably this was not later than that time, so near the southern coast, (which among the Britons themselves was the most civilised) so rich and fine a country: for Titus his father Vespasian, partly under Claudius the emperor, and partly under Aulus Plautius his lieutenant, conquered all the parts hereabouts (as we mentioned in the beginning of this letter) where he fought the Britons thirty times, subdued two of their most potent nations, took above twenty of their towns, and the whole Isle of Wight. No doubt but the people, inhabitants of this country, the _Durotriges_, and the town of Dorchester, _Durnovaria_, were included in his conquests; and they,
