Empereur Hadrian, also known as Hadrianus, serves as the 14th emperor of the Roman Empire during these events, ruling from 117 to 138 AD and counted among the Five Good Emperors. His governance emphasizes cultural development and peace instead of military conquest, believing the construction of new bathhouses (thermae) fosters societal harmony and stability empire-wide. This conviction leads him to engage the architect Lucius Modestus for crucial bath projects. Hadrian first commissions Lucius to design a private bath within his imperial villa, seeking a sanctuary for solitary thought amidst political turmoil like the Bar Kokhba revolt. Lucius incorporates innovative Japanese-inspired features, including bidet-equipped toilets and aquatic displays, securing Hadrian's trust. Subsequently, the emperor tasks Lucius with building therapeutic baths for soldiers during the Jerusalem campaign; these facilities heal poisoned troops and ease battle fatigue. Facing succession concerns, Hadrian publicly appoints Ceionius Commodus (Lucius Aurelius Caesar) as heir while privately intending the younger Marcus Annius Verus to ultimately rule. He worries about Commodus's frivolity and potential early demise disrupting the transition. To enhance Commodus's public standing, Hadrian assigns Lucius to create a bathhouse as the heir's inaugural project, aiming to win popular favor. This illustrates his strategic use of public works for political ends. References to historical complexities, such as his relationship with Antinous, exist but remain unexplored. Dedication to imperial duties strains his marriage, with his wife Livia expressing frustration over his constant absence. Despite these pressures, Hadrian remains a discerning architectural patron, recognizing and rewarding ingenuity that advances his vision of a prosperous Rome. Throughout, Hadrian's leadership consistently merges cultural progress with statecraft, utilizing bathhouse initiatives to meet practical needs and broader political objectives.
