Mr. Ibn Battuta (b.1304) was a Moroccan Muslim who spent 40 years exploring the medieval Islamic world of his time. He went to Mecca 7 times during his lifetime, and many other places as well.
At that time it was investigation by the seat of the pants. He explored, travelled, and geographized. And got on boats! He wrote a book called ‘The Travels’.
Had Mr. Ibn Battuta lacked an Inner Rhino, We wonder what might have become of him. Curiosity is hard on cats, but it often helps Rhinos thrive. Case in point, yes?
