According to Sidney, the force of innate poetic ability manifests itself most clearly in a poet's emotional vehemence, or energia: it is poetry's "forcibleness
"--the authentic display of emotion, an inborn trait--that gives life to poetry, not that "honey-flowing matron Eloquence apparelled, or rather disguised, in a courtesan-like painted affectation" (246).
than that in truth they feel those passions, which as easily (I think) may be bewrayed by that same forcibleness
or energia (as the Greeks call it) of the writer.
The sections on flogging and other violent sexual practices recall some of Swinburne's work, many others on the Orientalism that had gained forcibleness
in British arts from the eighteenth century, on through Byron's narrative verse, Burton's various writings, and Beardsley's pictorial work.
