Phosphatic mineralization of seeds from archaeological sites

Recent investigations of botanical material from archaeological sites have provided seeds and plant remains exhibiting a crystalline or semi-crystalline appearance. X-ray diffraction and partial chemical analysis have revealed that the particular plant materials had been replaced by calcium phosphate. Using systematic sampling and retrieval techniques a significant body of data has been accumulated. Most mineralized botanical evidence has been recovered from faecal deposits, in particular cess pits and garderobes, and has provided an important source of information about aspects of diet of past populations.     

Norman crusaders in the Catalan reconquest: Robert Burdet and the principality of Tarragona, 1129-55

A Norman adventurer, Robert Burdet, while participating in the Reconquista, established a short-lived crusader principality at Tarragona. This Norman gained fame after 1114, first serving Alfonso I el Batallador (‘The Warrior’) of Aragón in the wars against the Banu Hūd of Zaragoza; thereafter he was contracted by Archbishop Oleguer Bonestruga of Tarragona, the primate of northeastern Spain after 1118 and a papal legate after 1123, to assume in 1129 the secular lordship of Tarragona which had been constituted by the comital house of Barcelona as a papal fief and ecclesiastical principality. After this prelate's death in 1137, the Norman held this frontier and attempted to found an autonomous crusader state, but in 1146 the new archbishop, Bernard Tort, began to re-impose ecclesiastical control over Tarragona. At the same time, the house of Barcelona inherited the royal title from Aragón, thus forming the crown of Aragón by merging the former kingdom with the Catalan counties and reviving the crusade against Muslim Lérida and Tortosa which fell in 1148 and 1149. The archbishop and count moved against the Normans to integrate their principality into the new Aragó-Catalan federation. Prince Robert lost much of his power before his death in 1155, and his heirs were reduced to vassalage to Barcelona and subservience to their ecclesiastical lord, the archbishop of Tarragona. Civil war broke out after 1155 and the expulsion of the Normans by 1177 brought their principality to an end.     

MYCENAEAN POTTERY FROM CILICIA IN OXFORD

Summary. The Ashmolean Museum possesses a small group of Late Mycenaean (Late Helladic IIIC) sherds from Kazanli in Southern Cilicia, which it acquired in 1930. These are of interest since, although similar pottery is known from nearby Tarsus, they appear to be slightly later in date than most of the other pottery from Kazanli recovered by excavation or surface survey. One of them has a pictorial representation of an unusual nature.
The appearance of Mycenaean pottery in Cilicia has often been associated with the arrival of Mycenaean settlers (particularly refugee settlers) around 1200 B.C. However, it is doubtful whether the pottery really justifies this interpretation. Where identifiable, the Cilician Mycenaean seems to display closer links with Cyprus and the East Aegean than with the Greek Mainland; and, when other evidence is taken into account, there seems little reason to suppose that it is necessarily the result of colonisation from Mycenaean Greece.
