Answer: Bernardino de Sahagún
Explanation:
Bernardino de Sahagun was a Spanish Catholic missionary who worked in New Spain to convert the Aztecs to Christianity. He spent more than 50 years studying the culture of the Aztec and in so doing, learned their Nahuatl language which allowed him to translate Biblical text into Nahuatl.
He compiled the Aztec encyclopedia known as the Historia General in bilingual text of Spanish and Nahuatl which allowed for Europeans to better understand Aztec culture and language.
