Hirdan Gersenga

Hirdan Gersenga (15 May 1631 - 22 September 1687), more well-known under his pen name Erivinkisa meaning "Aged Quill", was a Risevan writer who is often regarded by Risevani as being one of their greatest writers. Working mostly in poetry while also being an expert essayist, Gersenga produced a total of 386 poems and nearly 700 essays, most of which have survived to this day; his essays, which are termed by him to be Kisa ta Omanoye or "The will of the pen", are considered pioneers of the form.

Some of his most famous works include his long poems, which he titled Navno te Wasantosa (meaning The New Wasantosas, the term referring to a specific sort of ode within the ancient poetic text Sayenfurasa), the longest of which - the Erunmitir ta Wasantosa or ode of Erunmitir - contains nearly 5,200 lines and has had a profound effect on literature even up to the modern era. His essays, on the other hand, portray a very different side of him; mostly composed during his years in the wilderness of modern-day Naguse Province, they possess a tone very different from that of his poetry.
