The term "uncial" refers to a rounded form of Greek or Roman majuscule
(capital) letters. Although some scholars derive the word "uncial" from
the Latin uncus, "hook" (a reference to uncials as hooked or bent
capitals), most trace the word to the Latin uncia, "a twelfth part," a
term used by Jerome in the introduction to his translation of Job to
refer disparagingly to Greek manuscripts that used ostentatious letters
"an inch wide." Both Greek and Latin texts from the third through ninth
centuries C.E. were written in uncial script; after this time, minuscule
characters almost completely replaced uncials.
Uncial letters were used to write early lectionaries and papyrus
manuscripts, but the term "uncial" is often used to refer to those
manuscripts of the Old and/or New Testaments written in uncial characters
on parchment. More than 300 uncial manuscripts, most fragmentary, are
extant. Among the more important uncial manuscripts that contain
significant portions of both the Old and the New Testaments are Codices
Alexandrinus (A), Vaticanus (B), and Sinaiticus ( or, in reference to the Old
Testament, S).
