Final answer:
The Aztecs are better known due to their picture writing system, extensive libraries, and surviving post-conquest Spanish documents.
Explanation:
The Aztecs are better known compared to other South and Central American societies primarily because:
- They had an extensive system of picture writing: The Aztecs recorded their history and religious practices through pictures and had real books written with these pictures.
- They established an extensive system of libraries: The Aztecs had a system of codices, book-like records drawn on bark paper, which provided invaluable insights into their culture and history.
- The surviving information mainly comes from post-conquest Spanish documents: Many pre-Hispanic codices were destroyed, and post-conquest manuscripts by Spanish chroniclers became important sources for understanding Aztec civilization.
