SIXSix Months ago I sent to Dr. Lister a large Account of the Texture and Figure of an old Roman Shield of the Parma Kind, that I had then newly procured; I have since got another Curiosity relating to their Plasticks, 'tis part of the Bottom (which consisted of several such Pieces for the Conveniency of Baking) of an old Roman Coffin, that was lately dug up in their Burying-Place out of Boutham-Bar at York, (whence I had the Bricks and Urns mentioned in the last November Transactions) 'tis of the Red Clay but not so fine as the Urns, having a greater Quantity of course Sand wrought in with the Clay; as to the Form (which is entire as it was at first moulded) 'tis Fourteen Inches and an half long, and (311) about Eleven broad at the narrower End, and nigh Twelve and an half at the broader; this was the lowest part, for the Feet and the rest were proportionably broader till it came to the Shoulders; 'tis an Inch thick besides the Ledges, which are One broad and Two thick, and extend from the bottom of either side to within Three Inches of the top, where 'tis wholly flat, and somewhat thinner for the next to lye upon it, which several Parts were thus joyn'd together by some Pin, I presume, for at the end of each Tile is a Hole that wou'd receive a common Slate-Pin, these Edges are wrought a little hollow, to receive the Sides, I suppose, and at the Feet are Two contrary Notches to fasten the End-piece, this Bottom I should conclude to have consisted strictly of Eight such Parts, from a like Character 8 imprest upon the Clay by the Sandapilarius's Finger before its Baking, but that I somewhat doubt whether Numeral Figures be of that Antiquity in these European Parts, tho' I see no reason to conclude that because the Romans used the Numeral Letters upon their more durable Monuments, that they were utterly Strangers to these Figures, which (notwithstanding the common Opinion of their Novelty here) the learned Dr. Wallis thinks as old at least, as the Times of Hermannus Contractus, An. Dom 1050. and produces an unexceptionable Testimony of their Use here in England An. 1133. Philosoph. Transact. Numb. 154.) I got also some Scars of broken Urns, dug up in Mr. Giles's Garden, which are of the finest blew Clay I have seen, with which was found a Roman Shuttle, about Three Inches and an half long, but not one broad in the very middle, the hollow for the Licium being but one fourth of an Inch in the broadest Place, shews that it was either for Silk or very fine Linnen, perhaps their Asbestinum or Incombustible Winding-Sheets. I have also lately procur'd a Roman Pottle from (312) Aldbrough, which is of the Red Clay, but much courser than the York Urns: I was well pleased to find it whole, that I might observe the difference betwixt their Congius (of which I take this to be strictly the half) and our Gallon, and this comes the nighest Mr. Graves's Computation, containing Three Pints and an half the Winchester Measure.
