In general, there are some common features of uncial script:
In later uncial scripts, the letters are sometimes drawn haphazardly; for example, ⟨ll⟩ runs together at the baseline, bows (for example in ⟨b⟩, ⟨p⟩, ⟨r⟩) do not entirely curve in to touch their stems, and the script is generally not written as cleanly as previously.
The word, uncial, is also sometimes used to refer to manuscripts that have been scribed in uncial, especially when differentiating from those penned with minuscule. Some of the most noteworthy Greek uncials are:
The Petropolitanus is considered by some to contain optimum uncial style. It is also an example of how large the characters were getting.
For further details on these manuscripts, see Guglielmo Cavallo Ricerche sulla Maiuscola Biblica (Florence, 1967).
Modern calligraphy usually teaches a form of evolved Latin-based uncial hand that would probably be best compared to the later 7th to 10th century examples, though admittedly, the variations in Latin uncial are much wider and less rigid than Greek. 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.
In a way comparable to the continued widespread use of the blackletter typefaces for written German until well into the 20th century, Gaelic letterforms, which are similar to uncial letterforms, were conventionally used for typography in Irish until the 1950s. The script is still widely used in this way for titles of documents, inscriptions on monuments, and other 'official' uses. Strictly speaking, the Gaelic script is insular, not uncial. Uncial Greek (commonly called "Byzantine lettering" by Greeks themselves) is commonly used by the Greek Orthodox Church and various institutions and individuals in Greece to this day. The Modern Greek State has also used uncial script on several occasions in official capacity (such as on seals, government documents, etc.) as did many of the Greek provisional governments during the Greek War of Independence. The height of uncial usage by the Modern Greek State was during the Greek military junta of 1967–74, when even Greek Drachma coins had uncial lettering on them. Since the Metapolitefsi, the Greek State has stopped using uncial script.
