In this paper, through the example of Antonii Radyvylovskyi’s work, I examine the
impact of Seneca’s texts on the philosophical component of Ukrainian church sermons
from the Baroque period. The objective of this study is to investigate Radyvylovskyi’s
use of Seneca’s texts in his own writing. The result should help better understand
the ideological influence of ancient philosophy on the formation of the national
philosophical tradition of the Baroque epoch. The contents of ideological borrowings
from Seneca’s texts and the mechanisms of their use are traced. A list of Seneca’s texts
from which Radyvylovskyi quotes is provided. It is also shown that Radyvylovskyi
uses Seneca’s authority in his moral teachings and philosophical thinking about the
characteristics of human nature. We conclude by commenting on Radyvylovskyi’s
creative use of Seneca’s ideas and the significant philosophical component of his
written legacy.
