Prose
The word "prose" first appears in English in the 14th century. It is derived from the Old French "prose", which in turn originates in the Latin expression "prosa oratio" (literally, straightforward or direct speech).
Western culture
While epic literary works in verse such as the Mahabharata and Homer's Iliad are ancient and occurred worldwide, the prose novel as a distinct form of storytelling, with developed, consistent human characters and, typically, some connected overall plot (although both of these characteristics have sometimes been modified and played with in later times), was popularized by the West in the 17th and 18th centuries. Of course, extended prose fiction had existed much earlier; both novels of adventure and romance in the Hellenistic world and in Heian Japan. Both Petronius' Satyricon (c. 60 CE) and the "Tale of Genji" by Murasaki Shikibu (c. 1000 CE) have been cited as the world's first major novel but they had a very limited long-term impact on literary writing beyond their own day until much more recent times.
