Well, 'King Lear' by Shakespeare can also be considered in a way. It has elements of black verse and explores themes like power, family, and madness in a very profound way. Also, 'The Canterbury Tales' by Geoffrey Chaucer has some parts that are close to black verse, although it is more of a collection of tales. It gives insights into medieval society through its vivid characters and their stories.
A great example is 'Beowulf'. Although it is an epic poem, it has black verse - like qualities. It tells the heroic deeds of Beowulf in a solemn and rhythmic way. And then there's 'Moby - Dick' by Herman Melville. It uses black verse - like prose at times to convey the grandiosity and the dark themes of the hunt for the white whale and the nature of obsession.
