This study examines the physical form and cultic function of the biblical cherubim. Previous studies of the cherubim have placed too great an emphasis on archaeological and etymological data. This monograph presents a new synthetic study, which prioritises the evidence supplied by the biblical texts. Biblical exegesis, using literary and historical-critical methods, forms the large part of the investigation (Part I). The findings arising from the exegetical discussion provide the basis upon which comparison with etymological and archaeological data is made (Parts II and III). The results suggest that traditions envisaging the cherubim as tutelary winged quadrupeds, with one head and one set of wings, were supplanted by traditions that conceived of them as more enigmatic, obeisant beings. In the portrayal of the cherubim in Ezekiel and Chronicles, we can detect signs of a conceptual shift that prefigures the description of the cherubim in post-biblical texts, such as The Songs of the Sabbath Sacrifice and the Enochic texts.

Gathering the Proceedings of the 2018 Intelligent Systems Conference (IntelliSys 2018), this book offers a remarkable collection of chapters covering a wide range of topics in intelligent systems and computing, and their real-world applications. The Conference attracted a total of 568 submissions from pioneering researchers, scientists, industrial engineers, and students from all around the world. These submissions underwent a double-blind peer review process, after which 194 (including 13 poster papers) were selected to be included in these proceedings. As intelligent systems continue to replace and sometimes outperform human intelligence in decision-making processes, they have made it possible to tackle many problems more effectively. This branching out of computational intelligence in several directions, and the use of intelligent systems in everyday applications, have created the need for such an international conference, which serves as a venue for reporting on cutting-edge innovations and developments. This book collects both theory and application-based chapters on all aspects of artificial intelligence, from classical to intelligent scope. Readers are sure to find the book both interesting and valuable, as it presents state-of-the-art intelligent methods and techniques for solving real-world problems, along with a vision of future research directions.
