What are the literary techniques used in the prose The Nightingale and the Rose?

"The Nightingale and the Rose" by Oscar Wilde uses several literary techniques, including personification (giving human qualities to animals and objects), symbolism (where the nightingale symbolizes selfless love), and allegory (the story's deeper moral lesson about sacrifice and the nature of love). These techniques help convey the themes of love, sacrifice, and the harsh realities of the world.
