This is an account of what their gods meant to the Romans from archaic times to Late Antiquity, and of the rites and rituals connected with them. The book is divided into three parts: the Gods of Earth and the family, devoted to archaic Rome; the Gods of City, covering the Roman Republic and early Imperial Rome; and the Gods of the Empire. Thoroughly up-to-date, receptive to the fascinating archaeological and epigraphic evidence, yet still very full on the relevant literary material, this book should be of interest for undergraduate students and for non-academic readers with a serious interest in the classical world.
