👉 Jaup, in Latin, is a type of writing system or script. It was used in ancient Roman and Byzantine times for both religious texts (as the "Apostolic Bible" for Christians) and for legal documents (such as the "Purto-Norman Codex"). The term comes from the Latin word "jacquus," which means "cross." The system is characterized by its use of a series of cross lines, often with a horizontal line separating each line.
