Within hours, he had written his first palindrome, at a length that most people couldn't achieve in a month, or maybe ever.

Origin of palindrome
The earliest known palindrome was found at Herculaneum, which was buried along with neighboring Pompeii in the eruption of Mount Vesuvius on August 24, 79 a.d. The palindrome was written in Latin and is known as the “Sator Square.” The square is also a word square, that is, when the words are arranged one beneath another in a square, they read the same horizontally and vertically. The square reads "SATOR AREPO TENET OPERA ROTAS" and is capable of several translations, the most plausible being “The sower Arepo holds the wheels with care.” Its significance and purpose have been vigorously debated since the late 19th century. The word palindrome was coined by the English poet and dramatist Ben Jonson (c1573–1637).
