Fans of French literary giant Marcel Proust will soon have the chance to read nine novellas from early in his career that were only unearthed in 2018, the Fallois publishing house said Monday.

The nine texts by the author of Swann's Way were originally to be part of his first book, Les Plaisirs et les Jours (Pleasures and Days), a collection of poems and short stories published in 1896.

But Proust, who was still in his 20s, later decided not to include them.

They were uncovered by the publishing house's founder Bernard de Fallois, a noted Proust specialist who died in 2018.

It will issue the collection on October 9 under the title The Mysterious Correspondent and Other Unpublished Novellas.

"With this diverse collection of previously unpublished novellas and texts, we discover the sources of Swann's Way," the house said in a statement.

Fallois had previously discovered a Proust novel that went unpublished in his lifetime, Jean Santeuil, as well as an unfinished text called Contre Sainte-Beuve. Both were eventually published in the 1950s.

Proust, who died in 1922 at the age of 51, has been hugely influential for subsequent generations of authors, in particular for the masterpiece In Search of Lost Time, also called Remembrance of Things Past, the first volume of the Swann works.

A copy of that book, dedicated by Proust to his lover, sold at auction in December 2018 for 1.51 million euros ($1.7 million), a record for a French book.

The newfound texts show a young writer dabbling in new narrative techniques while exploring such risque themes for the era as physical love and homosexuality.

"Because of their audacity, he probably thought they would offend a social milieu dominated by traditional moral forces," the publisher said.

The 180-page collection will include facsimiles of the original texts as well as analysis and critiques.
