[![Korean orthogonal Latin square](https://i.sstatic.net/zavj2.jpg)](https://i.sstatic.net/zavj2.jpg)

It's an old Korean orthogonal [Latin square](https://en.wikipedia.org/wiki/Latin_square) attributed to Choi Seok-Jeong, in the book Koo-Soo-Ryak. It's of historical interest, since it predates Euler, and he's usually the one attributed to inventing Latin squares. It's probably in the ballpark of 300 years old.

* I have a feeling the second character ？ is「衡」.
* Please be wary of phonetic loans. For example,「從」might be better off being interpreted as「縱」. With the above, you have the two characters as「縱衡」(*vertical and horizontal*).
