Uncial is a majuscule[1] script (written entirely in capital letters) commonly used from the 4th to 8th centuries AD by Latin and Greek scribes.
In the oldest examples of uncial, such as the fragment of De bellis macedonicis in the British Library, of the late 1st–early 2nd centuries,[3] all of the letters are disconnected from one another, and word separation is typically not used.
Due to its extremely widespread use, in Byzantine, African, Italian, French, Spanish, and "insular" (Irish, Welsh, and English) centres, there were many slightly different styles in use: There is some doubt about the original meaning of the word.
Modern uncial has borrowed heavily from some of the conventions found in more cursive scripts, using flourishes, variable width strokes, and on occasion, even center axis tilt.
The Modern Greek State has also used uncial script on several occasions in official capacity (such as on seals, government documents, etc.)
The term half-uncial or semi-uncial was first deployed by Scipione Maffei, Istoria diplomatica (Mantua, 1727);[6] he used it to distinguish what seemed like a cut-down version of uncial in the famous Codex Basilicanus of Hilary, which contains sections in each of the two types of script.
Despite the common and well-fixed usage, half-uncial is a poor name to the extent that it suggests some organic debt to regular uncial, though both types share features inherited from their ancient source, capitalis rustica.
The early forms of half-uncial were used for pagan authors and Roman legal writing, while in the 6th century the script came to be used in Africa and Europe (but not as often in insular centres) to transcribe Christian texts.
