Of the tessellated Pavements, or Dice-like Squares of Stone or Brick, wherewith the Romans used to pave the Place, where they set the Prætorium, or General's Tent, &c. Here are various Specimens of different Sizes and Colours (white, red, blue, yellow, and black) and from very distinct Places; as from the ancient Isurium (Aldbrough) from a Quarter to half an Inch Square: Also some of a larger Sort, dark coloured and red, which I took from a checquered Pavement discovered there, An. 1702, within a Stable; these are an Inch Square. I saw the by Musaic Work (in May 1703) as laid by the Romans. Some of both Sizes as sent me Mr. Midgeley of Beverley, from a Pavement lately discovered in those Parts, which hath not yet met with a Person of Curiosity enough to give the World an Account of it. Four of those from the noted Stunsfield Pavement near Oxford, concerning which the ingenious Mr. Hearne hath a learned and curious Dissertation, annexed to the 8th Vol. of Leland's Itinerary. Lapides tessellati pavimenti apud Roxby in Com. Lincolniensi, An. Dom. 1699 reperti. Don. D. Rog. Gale Arm. The very Learned Dr. Gale, late Dean of Yorke, sent me two conjoined, and some of the painted Plaister from the same Place; of which see the industrious Mr. de la Pryme's Account in the Phil. Trans. N° 263, though the Passage of Dr. Lister's he refers to, is in the Phil. Collections (N° 4.) not Transactions. A Specimen of the Roman Plaister at Buxton, mentioned by Dr. Leigh in his Nat. Hist. (Lib. 3. p. 42.) Stones of the larger Sort from a tessellated Pavement discovered by the Reverend Dr. Pearson at Kirkby upon Wherfe, near Tadcaster: A Piece of eight of them with the Floor and Cement, as set by the Romans. Don. D. Gul. Pearson Canc. Ebor. Some of the smaller sort set in a finer Cement, sent me from Ireland by Sam. Molyneux Esq; with some Fragments of the Coralline and white Urns, which leads me to another Branch of the Roman Plasticks.
