Metallurgical ceramics from Mayapán,Yucatán,Mexico

Recent excavations at the Postclassic (AD 1050–1440) Maya site of Mayapán, Mexico, have uncovered a variety of metal objects, metal production debris, and ceramic objects that appear to be linked to metallurgical activities at the site. Our present study investigates a corpus of small ceramic objects to determine if these objects was used in metallurgical processes such as lost-wax casting. A variety of analytical techniques was utilized, including x-ray fluorescence, electron probe, petrography, and reflected light microscopy. Metal residues were detected on the surfaces of several objects, and copper prills were identified within the ceramic fabric, suggesting that the ceramics were exposed to liquid metal during remelting and/or casting events. A comparison of the microstructures of these metallurgical ceramics to typical ceramics from Mayapán demonstrates that the fabrics are very different, and suggests that the metallurgical ceramics were specifically engineered to function in the high temperature environment required for metallurgy. The distribution of metal and metallurgical ceramics across the site of Mayapán suggests that metal production activities may have been more widely distributed and practiced than earlier thought.     

A possible case of metastatic carcinoma in a middle Sican burial from Batán Grande,Perú

The skeleton of a young to middle-aged adult excavated at the base of the Pre-Incaic pyramid of Huaca Las Ventanas, northern coast of Peru, shows an osteoplastic formation on the fifth lumbar vertebra compatible with a diagnosis of metastatic carcinoma, possibly from the prostate gland.     

Durán of Huesca (c. 1160–1230): A Waldensian Seeking a Remedy to Heresy

Despite the debates about the nature of medieval heresy, especially the Cathars and the Waldensians, in recent scholarship, very little attention has been given to Durán of Huesca, a Spanish Waldensian who wrote two anti‐heretical treatises before and after he was reconciled with the Roman Church in 1207. This article examines how Durán's decisions to join the Waldensians and later to return to the Catholic Church were motivated by his commitment to defending the sacraments and the Incarnation against what he saw as dualist heresy. That his major decisions were in response to this heresy suggests that while old scholarship might overemphasise the cohesiveness of heresy in the south of France, it is important not to dismiss the existence of explicit heretical belief altogether. Moreover, the centrality of the Incarnation and the sacraments in Durán's shifts in association reveals that the Waldensians were active, rather than passive, participants in shaping how the Church hierarchy and other dissident groups perceived and categorised them.
