Nikolai Semyonovich Leskov, born on February 4, 1831, in Gorokhovo, Russia, is esteemed for his unique storytelling techniques and proficiency in Russian literature. As an author, Leskov's works often illuminated the intricacies of Russian society, spirituality, and the myriad personalities that populated the 19th century. 'The Sealed Angel' is one of his notable works that highlight Leskov's narrative prowess and gift for imbuing folklore with a theological and moral depth. His narratives wove a complex tapestry of Russian life, blurring the lines between the folkloric tradition and sophisticated literary devices. Although Leskov was initially less celebrated than his contemporaries, such as Tolstoy or Dostoevsky, his recognition as a literary figure has posthumously grown, acknowledging his adept use of skaz, a narrative technique, which mimics oral storytelling, rich with vernacular speech and idiosyncratic point of view. This technique is exemplified in his craftsmanship of the characters and dialogue within 'The Sealed Angel' and other writings. Despite the challenges of modern interpretation, Leskov's contribution to the canon of Russian literature is significant, earning him a place among the celebrated authors of his country. He passed away on March 5, 1895, in St. Petersburg, but his literary legacy continues to influence and challenge readers and scholars alike.
