Using ALL CAPS in today’s written communication can mean everything from HIGHLY IMPORTANT to URGENT. Or if you’re texting, it’s akin to SHOUTING! However, in the Greco-Roman world the use of ALL CAPS—known as UNCIAL script—served a practical purpose. It was simple to write and easy to read. This also made it easier to copy words accurately. But did you know that several significant Bibles were written entirely with uncial script? One of the most well-known is the Codex Sinaiticus—a 4th-century manuscript containing the oldest complete copy of the New Testament. Uncial manuscripts were used, particularly in Bibles, until around the ninth century, and over 300 New Testament uncial manuscripts still survive.
