Final answer:
Magical realism is characterized by the blending of fantastical elements with realistic settings, often described in meticulous detail, as seen in García Márquez's works. Intertextuality, on the other hand, involves referencing other literary works through quotations, allusions, or conceptual ideas, as well as employing techniques like metafiction.
Step-by-step explanation:
Techniques that are typical for intertextuality often include direct quotations, allusions, or ideas from other texts, whereas magical realism characteristically blends fantastical elements with a mundane, realistic setting. For instance, Gabriel García Márquez, in his novel 'One Hundred Years of Solitude', infuses the narrative with magical events treated as ordinary, such as a character levitating or a rain of yellow flowers, presented in the same factual tone as one would describe a commonplace event. This seamless integration challenges the reader's preconceived notions of reality.
Intertextuality may also include parody, pastiche, and rewriting of classic texts, which is a way of engaging with the literature of the past to create new meanings in a contemporary context. In terms of magic realism, authors like Márquez, Jorge Luis Borges, and Isabel Allende adopt a narrative approach that deeply incorporates cultural and historical experiences within the fabric of their fantastical stories, mirroring the complex nature of Latin American history and societal experiences.
In addition to the use of supernatural elements in an otherwise normal setting, authors of magical realism often employ meticulous descriptive detail that makes the unbelievable elements seem credible, much like the gritty description of the angel in 'A Very Old Man With Enormous Wings'. Intertextuality, on the other hand, plays with the form of literature, the notion of authorship, and can involve innovative storytelling techniques such as metafiction, which is evident in works like Donald Barthelme's 'The School' where the story comments on the act of storytelling itself.
