The following passage from The Picture of Dorian Gray sums up Wilde’s rise and fall. He more than anyone characterized the last decade of the nineteenth century—the Fin de siècle decade. However, his imprisonment (1895-1897) was hard on him and he lived only three years after his release. He died in the year 1900 at the age of 46. So Wilde met his end of the world (Fin du globe) too early.

“Nowadays all the married men live like bachelors,
and all the bachelors like married men." 


"Fin de siècle," murmured Lord Henry.

"Fin du globe," answered his hostess.

"I wish it were fin du globe," said Dorian with a sigh.
"Life is a great disappointment" (131).



The "disappointment" Dorian experiences is a feature of the decadence of this lifestyle. The following link tells about the Fin de siècle sub-culture.

The following passage from Oscar Wilde’s The Picture of Dorian Gray has Dorian reading the Yellow Book, which is a gift from Lord Henry.  This "yellow book" is understood by critics to be A Rebours by Joris-Karl Huysmans, a representative work of Parisian decadence. 

“His eye fell on the yellow book that Lord Henry had sent him.
What was it, he wondered. He went towards the little,
pearl-coloured octagonal stand that had always looked to him
like the work of some strange Egyptian bees that wrought in silver,
and taking up the volume, flung himself into an arm-chair and began
to turn over the leaves. After a few minutes he became absorbed.
It was the strangest book that he had ever read. It seemed to him
that in exquisite raiment, and to the delicate sound of flutes,
the sins of the world were passing in dumb show before him.
Things that he had dimly dreamed of were suddenly made
real to him. Things of which he had never dreamed were
gradually revealed” (91).

The Yellow Book, a quarterly literary journal, is the quintessence of the 1890s, which was called the Fin de siècle era.  This journal featured leading authors associated with the movement.  The Yellow Book is described in the following:

The Picture of Dorian Gray exemplifies the decade that is associated with the Yellow Book.

The following are allusions to Oscar Wilde in James Joyce's Ulysses.

Telemachus:
"Laughing again, he brought the mirror away from Stephen's peering 
eyes.

Wilde were only alive to see you! 

Drawing back and pointing, Stephen said with bitterness:
 
-- It is a symbol of Irish art. The cracked looking-glass of a servant."
****

" -- Pooh! Buck Mulligan said. We have grown out of Wilde and paradoxes. It's quite simple. He proves by algebra that Hamlet's grandson is Shakespeare's grandfather and that he himself is the ghost of his own father."


Proteus:
"He lays aside the lapboard whereon he drafts his bills of costs for the eyes of master Goff and master Shapland Tandy, filing consents and common searches and a writ of DUCES TECUM. A bogoak frame over his bald head: Wilde's REQUIESCAT. The drone of his misleading whistle brings Walter back."
***

"Staunch friend, a brother soul: Wilde's love that dare not speak its name. His arm: Cranly's arm. He now will leave me. And the blame? As I am. As I am. All or not at all."


Scylla and Charybdis:
" -- The most brilliant of all is that story of Wilde's, Mr Best said, lifting his brilliant notebook. That PORTRAIT OF MR W. H. where he proves that the sonnets were written by a Willie Hughes, a man all hues. 

-- For Willie Hughes, is it not? the quaker librarian asked.
Or Hughie Wills? Mr William Himself. W. H.: who am I? 

-- I mean, for Willie Hughes, Mr Best said, amending his gloss easily. Of course it's all paradox, don't you know, Hughes and hews and hues, the colour, but it's so typical the way he works it out. It's the very essence of Wilde, don't you know. The light touch.

His glance touched their faces lightly as he smiled, a blond ephebe. Tame essence of Wilde."

" -- Are you going to write it? Mr Best asked. You ought to make it a dialogue, don't you know, like the Platonic dialogues Wilde wrote."


The Wandering Rocks:
"Cashel Boyle O'Connor Fitzmaurice Tisdall Farrell walked as far as Mr Lewis Werner's cheerful windows, then turned and strodeback along Merrionsquare,his stickumbrelladustcoat dangling.

At the corner of Wilde's house he halted, frowned at Elijah's name 
announced on the Metropolitan hall, frowned at the distant pleasance of duke's lawn. His eyeglass flashed frowning in the sun. 

With ratsteeth bared he muttered:

-- COACTUS VOLUI."
