Celestial Inclinations provides a new perspective on the life and career of the first Roman emperor Augustus (63 B.C.-A.D. 14). It presents the case that Augustus used his knowledge of the celestial sphere to confirm for himself and convey to others that the heavens supported his activities on earth and his inevitable greatness. The book is based on fresh assessments of ancient historical, literary, astronomical, astrological, and artistic sources for the years prior to and during the life of Augustus. Anne-Marie Lewis combines these sources with astronomical sky maps and astrological diagrams to offer fresh interpretations of critical events in the life of Augustus at a time when the celestial sphere had come to play an important cultural and political role. Some of those events involve the identification of the celestial object that appeared at the ludi in honor of Caesar in 44 B.C.; the Battle of Actium; the iconography of the Tellus Relief Panel on the Ara Pacis Augustae; the Ludi Saeculares; Augustus' major building projects in Rome; and Augustus' interactions with major figures of the period such as Cicero, Caesar, Agrippa, and Antonius.

"[Lewis'] unique approach employs astronomical and astrological works as the foundational evidence for Augustus's actions, resulting in an analysis of the emperor based on astronomical sky maps at an unprecedented level. This analysis yields new interpretations of Augustus's reign and provides a better understanding of the Roman ruler. It offers a novel approach to understanding Augustus and Roman society during his life and provides an opportunity for Roman scholars to reimagine the relationship Roman elites had with Roman religion...Highly recommended." - Choice
