The above appraisal is from a recent edition of the U.S. version of Antiques Roadshow, and features a manuscript sonnet by Oscar Wilde which has recently come to light.
While it is a newly discovered manuscript, it is not a newly discovered poem. It is one from the Wilde canon which he retitled as Ideal Love andpresented with a dedication to an acquaintance named Christian Gauss, a young American journalist.
The sin was mine; I did not understand. So now is music prisoned in her cave, Save where some ebbing desultory wave Frets with its restless whirls this meagre strand. And in the withered hollow of this land Hath Summer dug herself so deep a grave, That hardly can the silver willow crave One little blossom from keen Winter’s hand.
But who is this who cometh by the shore? (Nay, love, look up and wonder!) Who is this Who cometh in dyed garments from the South? It is thy new-found Lord, and he shall kiss The yet unravished roses of thy mouth, And I shall weep and worship, as before.

Literary Metaphor at the Oscar Wilde Festival in Galway
Focused though I am on Oscar Wilde In America, I like to keep an eye on the bigger picture. However, I know that to see the brushstrokes up close it is sometimes necessary to depart from topical and geographical constraints and visit the works themselves.
So last weekend I attended the Oscar Wilde Festival in Galway, Ireland, where I discovered part of the canvas rendered in two books with contrasting techniques.
Oscar Wilde’s lecture in San Francisco on Irish Poets
On this day in 1882  at Platt’s Hall, Oscar Wilde delivered the ninth of ten consecutive lectures in California, and his fourth and last in San Francisco.
As San Francisco was the only city in America where Wilde lectured four times, he needed an additional lecture to add to the three he was already giving, which were: The English Renaissance, its evolutionary successor The Decorative Arts, and his usual alternative The House Beautiful.
Wilde chose as his subject Irish Poets and Poetry of the Nineteenth Century(referred to in some texts as The Irish Poets of ’48), an idea he had hinted at on St.Patrick’s Day in St.Paul, where he made a rare expression of Irish nationalist sentiment.
