This study examines aspects of Seth which suggest that throughout Egyptian history he was continually worshipped and indeed, at times, enjoyed some prominence, notably in the Pre- and early-Dynastic periods, during the Hyksos interlude of the Second Intermediate Period and during the Ramesside era of the 19th and 20th Dynasties. Whilst previous authors have devoted some scholarship to these various aspects of Seth there have been very few attempts to bring all these together and to demonstrate that rather than being something of an 'outsider' to the Egyptian pantheon, he actually had an important role within it, and as such was continually worshipped throughout ancient Egyptian history. In sum, the author examines the role of Seth as he was perceived by the Ancient Egyptians at specific times throughout their history. To achieve this aim a chronological approach is taken beginning with Seth's role in Predynastic Egyptian religion and then progressing through the early Dynastic and Old Kingdom, the FirstIntermediate period and the Middle Kingdom, the Second Intermediate Period, the New Kingdom, the Third Intermediate Period, the Late Period, and culminating with the Graeco-Roman Period up to the death of Cleopatra.
