In a predominantly secular age, in which religious practice is largely a personal matter, this work serves as a particularly valuable reference for us to understand the public role of religion in Ancient Rome. As a Latin teacher, I am often asked by my students if the Romans really believed their myths or if the Romans were really as superstitious as they seem or how the Romans grappled with the idea of gods whose actions often seemed petty or capricious. This work explores the contractual nature of worship of the gods. Humans for their part owe the gods worship, and in turn the gods to live up to their end of the bargain in terms of protection. The original Greco-Roman gods came to be joined by gods from other areas of the empire, bringing along with them new rituals, customs, and priesthoods. This work explores topics ranging from the traditional Greco-Roman gods, to the newer gods from elsewhere in the empire, to worship of the emperor, and to the practices of divination and magic. This text could serve as your ‘go to’ reference work for all aspects of Roman religion and the practical way in which religion played a central role in Roman society. Telford takes on an ambitious task in attempting to provide an accessible reference work on all aspects of Roman religion, and yet, in my opinion, she certainly is successful in providing a work that is equally of value to a neophyte as to a trained classicist.
