Final answer:
Pascal the Great was likely a successful and influential Mayan leader based on historical records found in Mayan codices, his involvement in advanced trade systems, and the sophisticated Mayan achievements in areas like mathematics, astronomy, and calendar systems.
Step-by-step explanation:
We can ascertain that Pascal the Great was a successful and influential Mayan leader through preserved Mayan codices and other archaeological evidence. These codices, although few, hold extensive historical records about the rulers and their reigns, including their achievements and long-distance trade. The Mayan civilization was notably advanced in mathematics, astronomy, and had a refined understanding of time as reflected in their sophisticated calendar systems.
Furthermore, the cities which held control over the trade routes, especially those exchanging valuable goods like gold, turquoise, and obsidian, tended to be more successful and influential. Leaders like Pascal the Great would have been at the forefront of such cities, which is a testament to their success. Lastly, the Mayan written script combined pictographs with alphabetic letters, allowing them to document their history, astronomy, and mathematics, leaving a legacy of their advanced knowledge despite the tragic loss of many texts during the Spanish conquest.
