What are Cistercian Numerals?

Cistercian numerals are a compact medieval number system used by Cistercian monks to represent numbers 1-9999 using a single glyph. Each digit position (ones, tens, hundreds, thousands) is represented by a distinct symbol placed in specific positions around a central vertical line, creating an elegant and space-efficient notation system.
