What differences do you notice between English and Irish Romantics?
The English Romantics include Coleridge, Blake, Lord Byron, Wordsworth, Mary and Percy Bysshe Shelley, and Keats, among the most notable.
The most notable Irish Romantics (my personal favorites) include Oscar Wilde, James Joyce, Thomas Moore, G.Bernard Shaw among others.
What is similar among them is their interest in bringing the essence of the concrete without the overuse of metaphor, that is, reality can be seen under the scope of feeling and emotion with deep description and flavor without substituting what is really being talked about with some figure of speech.
The English Romantics focused on the bucolic and pastoral settings, innocent character, charming yet simple language, and a disdain for overpopulated hyperbole. This, they had in common with the Irish.
The Irish Romantics did one more thing: They intended to create a revival of the Celtic traditions which were being opaqued by Britain for hundreds of years, and they re-told their folk tales into modern versions that could blend in with the British pre and Victorian society. The period of most fervor lasted around 30 years, and Thomas Moore was the biggest promoter of this style of story telling.
