Rare Roman Pietra Dura Table Top in the manner of Francesco Sibilio
perhaps representing the Occhio della Prividenza or ‘All-Seeing Eye’, the pupil formed of a star, the surrounding eye filled with coloured stones, the spandrels also in an extraordinary marble in ‘mouldy tongue’ shades, possibly a kind of Sicilian Jasper, all within an outer porphyry border
Francesco Sibilio was a Roman craftsman and merchant active in the first half of the 19th century who’s collection of semi-precious stones, hardstones and marble was well-known in its day. He was also considered one of the major experts in this field. Faustino Corsi in his treatise, Delle Pietre Antiche, Rome, 1845, records various pieces by Sibilio, and some particularly unusual stones were named after him in the 19th century.
Sibilio’s technique of putting together soft-paste ancient glass and hardsones, such as porphyry and serpentine, is unique, though his inlaid marble designs sometimes seem to be inspired by the Opus Sectile of 1st century AD Rome. Two table-tops in this technique signed by Sibilio have been sold by Christie’s – one dated 1823 as lot 267 on 11th May 2000; the second, dated 1824, as lot 123 on 11th June 1987. A table top by Sibilio in this technique, now in the Corning Museum of glass, was exhibited at the 1867 Paris Exhibition at which time it was ascribed by the Vatican to Giovanni Rossignani, who is recorded as one of the master craftsmen working in the Reverenda Fabbrica di San Pietro. Sibilio doubtless also had a workshop in the Vatican and, presumably, collaborated with Rossignani, though surprisingly little is known about his life. He certainly worked in just hardstones and, as exemplified in the present table, was famous for sourcing finely-figured examples of rare marbles.
Martine Newby in her 2003 treatise, Francesco Sibilio and the Re-use of Ancient Roman Glass in the Nineteenth Century, only gives a firm attribution of six table and gueridon tops to Sibilio (including the two signed examples cited above), so a panel that can be attributed to him is rare indeed – and perhaps rarer for being rectangular as all the aforementioned examples are circular.
