"What's this piece called?"
"A Bishop. What is it in Spanish, Sophie?"
"And in French, Agathe?"
Therein lies a story...
The old Arab form of chess had a piece called the elephant, which, unlike most elephants I know, could jump two squares at a time, diagonally. And 'al-fil' means the Elephant in Arabic (Pil in Persian).
But if you have a lump of stone, or wood, and you want to show that it is an elephant, you might carve two curving lines on it for tusks, or make two points on it to show the same.
