The excerpt below is from Current Literature—a journal of the Current Literature Publishing Co. (New York) which published monthly periodicals from 1888 to 1912.
This account is from an article in the October 1905 edition entitled “How Oscar Wilde Died” which was given to deny claims in a earlier issue that Oscar was still alive. Its source was the Paris correspondent of the BerlinerTageblatt.
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. 
As the poem has homoerotic overtones it is of interest for that reason alone as a curiosity. However, I wonder if curiosity can be stretched to significance?
A rediscovered letter by Oscar Wilde informs his relationship with anonymity
Wilde’s college exploits, his aesthetic entry into London society, the self-publicity of his American tour, and his rise to fame have all been well documented; and the story often distills to the crucial moment of his fall from grace, a short period in 1895 when fame turned to infamy.
But there is a more enduring, more subtle, and underlying theme that began with Wilde’s desire to be known: it was a journey through his art and life towards an imperative for anonymity.
