thechildofchristmas:bourtange:neato: a 13th-century number notation system created by european monksthis is…. actuallly really cool?like, this is probably the shortest number notation in existence and yeah, it’s tricky to use and absolute hell for doing math with, but the ability to denote a 4-digit decimal number into a single character is just really cool as an engineer and it probably had a ton of uses back then like denoting quantities or maybe even secret codeyou can probably draw this on a combination lock to remember the password and people would be none the wiser -- source link
