Answer 1

The person you are referring to is Juan Ponce de León. He was a Spanish explorer and conquistador known for being the first European to reach Florida and is famously associated with the legend of the Fountain of Youth. He was indeed called the "brave lion," discovered gold while in Puerto Rico, searched for the Fountain of Youth in Florida, and met his end due to a poisoned arrow during a conflict with indigenous people.
