Gathering Data

A top-down approach to the mineralized structures and developmental steps that can be separated in the shells of Pinctada margaritifera was carried out. Detailed characterizations show that each of the two major layers usually taken into account (the outer prismatic layer and the inner nacreous layer) is actually the result of a complex process during which the microstructural patterns were progressively established. From its early growing stages in the deeper part of the periostracal grove up to the formation of the most inner nacreous layers, this species provides a demonstrative case study illustrating the leading role of specifically secreted organic structures as determinants of the crystallographic properties of the shell-building units. Gathering data established at various observational scales ranging from morphology to the nanometer level, this study allows for a reexamination of the recent and current biomineralization models.

Oyster Cultivation

This is an abbreviated form of the original manuscript prepared by the author following 16 years' work at Dongonab Bay in the Red Sea in an attempt to establish a pearl oyster cultivation industry. The environmental conditions at Dongonab, the species of pearl oysters in the Red Sea, and the detailed biology of Pinctada margaritifera (L.), the species used for the experiments, are discussed. Details are given of the methods developed for the collection of spat and the cultivation of the pearl-shell to marketable size. It was unfortunate that the improvements designed in 1921 were not used for commercial production, because the Sudan Government did not continue the scheme.

A Pinctada margaritifera box was unearthed at Viminacium in 1985, at the site of Pe}ine, in a grave containing cremated remains. It was made from the shell of a pearl oyster (Pinctada margaritifera), an exotic clam whose habitat is tropical seas: the Indo-Pacific region, the Persian Gulf, and the Red Sea. Based on the grave type and a coin found in it, the box has been dated to the second half of the first and the first half of the second century AD. Morphologically and functionally, it represents a rare find in the territory of present-day Serbia and, together with the finds from Aquincum and Savaria, it is also a rare find of P. margaritiferae in the Central Balkans. It is a high-prestige item, indicative of contacts between Viminacium and the Near East, i.e. the area of present-day Israel, Jordan and Syria, where the workshops producing Pinctada boxes are alleged to have been. This text discusses the geographic-historical and, in particular, functional aspects of the P. margaritifera box as a symbol of Venus and a cultic prop in initiation rites.
