small silver Harpocrates, now in the British Museum. Nowhere has the pottery of antiquity been so abundantly discovered as at London. Roman kilns were brought to light in digging the foundations of St. Paul's, in 1677; specimens of the Castor pottery have been found here; Samian ware is abundant, as have been potters' stamps which present 300 varieties, fragments of clay statuettes, terra-cotta lamps, tiles, and glass; and among the Roman glass discovered in London are several fragments of a flat and semi-transparent kind, which have every appearance of having been used as window-glass. And still more curious it is to find that specimens of a glass manufacture termed pillar-moulding, and for which Mr. James Green took out a patent, have also turned up among the _débris_ of the Roman city. Mr. Green's patent had been worked for some years under the full belief that it was a modern invention, until Mr. Apsley Pellatt recognised in the fragments evidence of the antiquity of the supposed discovery.[10] Among the personal ornaments and implements of the toilet are the gold armillæ dug up in Cheapside in 1837; the tweezers, nail-cleaners, mirrors, and strigils of the city dames of Londinium; the worn-out sandals thrown upon the dust-heaps; the sporls, spindles, fishhooks, bucket-handles, bells, balances, cocks, millstones, mortars, and other utensils which show the resources of an opulent city in the enjoyment of ancient luxury, and of the choicest appliances of ancient civilization. Of Roman coins found in London, in the bed of the Thames, Mr. Roach Smith enumerates 2,000; from gravel dredged from the Thames, 600 were picked out; a hoard of denarii of the Higher Empire was found in the city; and vast quantities were found in removing the piers of old London Bridge. In excavating for the foundations of the new Royal Exchange, in 1841, was discovered a gravel pit, supposed by Mr. Tite, the architect, to have been dug during the earliest Roman occupation of London; and then to have been a pond, gradually filled with rubbish. In it were found Roman work, stuccoed and painted; fragments of elegant Samian ware; an amphora, and terra-cotta lamps, seventeen feet below the surface; also pine-wood table-books and metal styles, sandals and soldiers' shoes, a Roman strigil, coins of Vespasian, Domitian, &c.; and almost the very footmarks of the Roman soldier.
