This article is the first publication of a lead seal from a private collection that bears the image of the Incredulity of Thomas. Based upon epigraphy and decorative motifs the seal is assigned to the sixth century. It is the only known sphragistic example of the image of the Incredulity of Thomas and its iconography is compared to other contemporary examples in other media, especially objects of pilgrimage art, among which is a sixth-century gold medallion bearing a similar image, also (...) published for the first time. The image of the seal reflects the thought world of contemporary pilgrimage art and homiletical literature that stresses the believer's transformative participation in Thomas' faith in the reality of Christ's saving Resurrection.

Among Marian epithets one of the more obscure is the designation "the Egyptian." This article traces the term in modern Greek and Byzantine literature. The investigation centers on an icon reputedly painted by the Apostle Luke while he was living in Egypt. Our researches lead to the city of Attaleia where, according to legend, a Lukan icon had found its way. Textual evidence establishes that around this icon a healing cult of the Virgin Aigyptia flourished in the later 11th century. (...) The written record is confirmed by the seal of a certain bishop Theodosios of Atteleia. The obverse bears a representation of the Virgin accompanied by the epithet Aigyptia. (shrink)

Collapse is a term that has attracted much attention in social science literature in recent years, but there remain substantial areas of disagreement about how it should be understood in historical contexts. More specifically, the use of the term collapse often merely serves to dramatize long-past events, to push human actors into the background, and to mystify the past intellectually. At the same time, since human societies are complex systems, the alternative involves grasping the challenges that a holistic analysis presents, (...) taking account of the many different levels and paces at which societies function, and developing appropriate methods that help to integrate science and history. Often neglected elements in considerations of collapse are the perceptions and beliefs of a historical society and how a given society deals with change; an important facet of this, almost entirely ignored in the discussion, is the understanding of time held by the individuals and social groups affected by change; and from this perspective ‘collapse’ depends very much on perception, including the perceptions of the modern commentator. With this in mind, this article challenges simplistic notions of ‘collapse’ in an effort to encourage a more nuanced understanding of the impact and process of both social and environmental change on past human societies.
