The Eparch Collection of Roman, Byzantine and Islamic Weights
COPTIC (?) WEIGHTS

Egypt, Fatimid Period or later. 10th-13th century (?) / AH 3rd-7th century (?). Weight of 1/6 Ratl of 55 dirhams or 2 ounces (Bronze, 49x49x8mm, 171.58 g), probably Coptic but conceivably a Crusader commercial- or coin-weight. Cross-crosslet with floral ornaments coming from the upper and lower ends, and with a small square in each inner angle of the cross; all within a linear square frame itself surrounded by a floral border forming another square frame. Rev. Circular empty space surrounded by five inscribed concentric circles; in the space between the inner two and the outer three circles, 33 punched stars; outside the outer circle, engraved 'pointer-like' ornament, which forms a 'handle' like that found on an astrolabe. Apparently completely unparalleled, but see its publication as A. Mazarakis, "Three Weights," NomXhron 28, 2010, pp. 95-104, fig. D (this piece). An impressive and intriguing object. Very fine.

From the Eparch Collection, acquired from a private collection in London.
