Acquired 1980-2015. Ex Abelita family collection. Accompanied by an academic paper by military specialist Dr Raffaele D'Amato, dated 15 July 2019 and titled 'Eastern Roman Empire - Greek Fire Bomb or Hand Grenade (μεσαίον kακάβιον) 9th-11th century AD'.

Apart from the use of siphons or manual flame-throwers called cheirosiphona, special corps of Roman soldiers employed terracotta grenades, in the form of small jars, abundantly evidenced in archaeological excavations. They were called μεσαία kακαβιά or κυτροκακάβια where the former had a bulbous shape and the latter a more cylindrical form.

The Cosmatesque style was a characteristic type of ornamentation of Eastern Roman origin (opus alexandrinum) used by the Roman marble makers of the 12th and 13th centuries AD. It embellishes floors, ciboriums and cloisters of churches by means of polychrome marble inlays of varied and imaginative geometric shapes. The wider use of this decoration began in the 12th century, at which time techniques were improved: the Cosmati floors were made with pieces of stone cut in various shapes and sizes, a property quite different from the mosaics in opus tessellatum, in which the motifs were made from small units all having the same size and shape, or from the opus sectile, intended to create representations with pieces of multicoloured marble cut out and arranged for this purpose. The stones used by Cosmati artists were often material salvaged from the ruins of ancient Roman buildings.

An imposing panel divided to four sections by a central cross on a stepped pedestal, the lower and upper arm with branch-like extensions; the upper quadrants with a circlet surrounding a palm tree-shaped motif; each lower quadrant with a bird in profile facing back; mounted on a custom-made display stand. 16 kg total, 44.5 cm including stand

The cross, symbol of resurrection and salvation, carried the meaning of Paradise, and a cross on a stepped base derived from that on Golgotha. The birds represented here are probably a symbol of joy of the afterlife, of paradise conceived as the locus refrigerii or refrigerium of the soul. The panel could have been part of a marble iconostasis of a Church of the Eastern Roman Empire, in Southern Italy, although the use of porphyry can suggest a Constantinopolitan provenance.
