The introductory sections of Part I include a chapter on the seasons of the year as regulators of human activity. The chapter discusses how various strata of the population viewed the four seasons, the round of everyday life and the development of events in an annual cycle, as well as the limitations posed by weather on activity and communication. Scenes from everyday life and relevant allegories reveal both the conveniences and the difficulties brought by the seasons of the annual cycle. Aspects of the seasonal rhythm of human activity are presented, using rhetorical and actual information preserved in the correspondence. This helps the reader to detect the various levels of connection of all social groups with the natural environment. The ability of agricultural populations to adapt and be resilient in the face of crises is a quality that was exercised all year round, because these populations never ceased to function and relied on their accumulated expertise and skills to complete tasks in a wide range of weather and climate conditions. This chapter may demonstrate aspects of human adaptability, which were exercised continually, reinforcing social resilience in the face of natural disasters.
