Between the sixth and eighth centuries CE, the image emerged as a rhetorical category in religious literature produced in the Mediterranean basin. The development was not a uniquely Christian phenomenon. Rather, it emerged in the context of broader debates about symbolic forms that took place across a wide range of ethnic, linguistic, and religious groups who inhabited the late Roman and early Byzantine world. In this book, Alexei Sivertsev demonstrates how Jewish texts serve as an important, and until recently overlooked, witness to the formation of image discourse and associated practices of image veneration in late antiquity and the early Middle Ages. Addressing the role of the image as a rhetorical device in Jewish liturgical poetry, Sivertsev also considers the theme of the engraved image of Jacob in its early Byzantine context and the aesthetics of spaces that bridge the gap between the material and the immaterial in early Byzantine imagination.

Summary

Sign systems help to create descriptive and depictive representations. Descriptive representations operate on symbols. They are based on conceptual analyses identifying objects or events as well as attributes and interrelations. Attributes and relations are ascribed by predications to entities according to syntactic rules resulting in so-called propositions (“idea units”). These propositions can be integrated into coherent semantic networks. Propositional representations are considered as mental structures which can be externalized in the form of spoken or written texts. Despite their informational incompleteness, descriptions have high representational power. Depictive representations are based on inherent commonalities between a representing object and the represented subject matter. The inherent commonalities can be based on similarity or analogy. These representations are complete with regard to a certain class of information. Due to their completeness and consistency and because information can be read off directly, depictive representations have high computational efficiency.

Multimedia messages use combinations of texts, pictures, maps, and graphs as tools for communication. This book provides a synthesis of theory and research about how people comprehend multimedia. It adopts the perspectives of cognitive psychology, semiotics, anthropology, linguistics, education, and art. Its central idea is that information displays can be categorized into two different but complementary forms of representations, which service different purposes in human cognition and communication. Specific interaction between these representations enhances comprehension, thinking, and problem solving, as illustrated by numerous examples. Multimedia Comprehension is written for a broad audience with no special prior knowledge. It is of interest to everyone trying to understand how people comprehend multimedia, from scholars and students in psychology, communication, and education, to web- and interface-designers and instructors.
