This revision of the original Dictionary published in 1986 includes a completely new Introduction in which I have tried to provide some crucial historical data and a chronological framework of the visual and textual sources for the individual entries. Also I have taken the opportunity to add four new deities and expand the information on a number of others. There is now a more comprehensive time chart and the Select further reading has been updated to reflect the significant number of salient books now available on Egyptian religion.

I would initially like to thank Vivian Davies, Keeper of the British Museum Department of Ancient Egypt and Sudan, for having given me the opportunity to write the first edition of this Dictionary. This new edition is enhanced by the addition of hieroglyphs for most of the gods’ names and my thanks go to Dr Nigel Strudwick, British Museum Department of Ancient Egypt and Sudan for producing these. Also I am grateful to Garth Denning who has used his skills as an archaeological illustrator to add a new map and some additional drawings. Obviously I would like to express my gratitude to the editorial staff at Routledge for enabling this new edition to be produced.
