Final answer:
Sandra Cisneros's use of Tepeyac in her writing relates to the theme of cultural and national identity, as it embodies the historical and religious significance of the site in Mexican culture and history.
Step-by-step explanation:
The author Sandra Cisneros uses Tepeyac, a historical and religious site, as the backdrop for her narrative. In the context of this question, Tepeyac serves as a symbol not only of her grandfather's small shop but also of the broader theme of cultural and national identity.
The location is deeply rooted in Aztec culture and its view of the world as a 'slippery' place, a term reflecting the Aztec belief in cyclic change and the need for stability amidst shifting realities. Moreover, the site's link to the Aztecs, viewed by them as the 'Gathering Place of the Gods,' where they believed the gods created the sun and the moon, ties in closely with this theme.
The historical narrative and cultural significance of Tepeyac, expressed through art and murals like those of Siqueiros and Rivera, evoke stories of the past that resonate with Mexican identity and history, influencing the community's self-conception and pride. These narratives highlight the Indigenous people's tenacity in maintaining their identity despite colonial conquest and changing times. Thus, Cisneros's use of Tepeyac in her literature is reflective of the intricate relationship between place, culture, and identity.
