Greek Letter Lamda (Λάμδα - Λ)

The letter "λ" came from the Semitic alphabet, where it always had the shape of an angle, but its orientation varied. Sometimes the "L"'s would even indicate whether the line was to be read right-to-left or left-to-right. The Greeks used the letter with the angle pointing up. It was turned on its side by the Romans to become the Latin "L".
