as if one entire Brick. But when the outfide of the 
Pavement was broke up, we found, that inftead of 
Bricks fet on Edge, as was imagin’d, it was bounded 
with a Border of Bricks laid flat, and their ends next 
the Tf(fer£ turn’d up. The Thickncfs of thefe Bricks was 
an Inch and a Quarter ; the Breadth not under Eleven, 
and not more than twelve Inches; the length full fif- 
teen Inches ; which, before they were turn’d up at their 
Ends, could not have been lefs than Seventeen. They were 
very firm, and not in the leaft Warp’d or Cad in Burn- 
ing ; when broke, their Subftance was fine and well 
mixt, of as uniform and clean a Red Colour, as a piece 
of fine Bole: Except at the ends wliere turn’d up, they 
were all over cover’d with a Plafter (the fame which 
Vitruvius calls the Nucleus, of which more afterwards), 
half an Inch thick ; fb hard, entire, and even, that it 
feem’d as one Stone, quite round the Pavement. 
Next within the Bricks, there was a Lift or Bordet 
of white TefjerA, thirteen Inches broad; within that, a 
Lift of brown Teffera (fomewhat darker than a Whet- 
Stone, and fomewhat lighter colour’d than the Touch- 
Stone ) four Inches broad ; then a Lift of the White, 
five Inches broad ; next within that, another Lift of the 
Brown, four Inches broad : all the reft of the Pavement 
was fet with white Teffera, without any Ornament or 
Figure ; which though not Gay, lookt very Neat and 
Clean. 
When' this was firft view’d, none of the Curious 
doubted, but that the Work was Roman, many were of 
opinion, that it might have been the Floor of a Temple, 
or place of Worftiip- Pli^y indeed (a) informs us, that 
thefe fort of Pavements or Lithofirota^ began to be in 
ufe in Italy, in the time of SylU ; who caus’d one of them
