Since the Indic writing systems used for Sanskrit are syllabic, each syllable can be thought of as representing a square on a chessboard. The same verse in four lines of eight syllables each can be read from left to right or by following the path of the knight on tour.

The knight's tour as solved by the Turk, a chess-playing machine hoax.
