I came across the concept of minuscules quite recently. Wikipedia says that they are manuscripts written with small font sizes. How do they matter more or less than any other Christian manuscript? Is there any particular relevance to minuscules apart from being used heavily for the translation of the Bible?
When the New Testament books were written the handwriting was uncials, which looked more like capital letters, with no punctuation.
Minuscules introduced separate capital and small letters, word spacing, and punctuation (the basis of modern handwriting). It didn't appear until the ninth century.
A modified form of Greek cursive handwriting (“rather small”), introduced in the 9th century c.e. More formal and more legible than ordinary cursive, minuscule writing enabled scribes to write more quickly and by the end of the 10th century supplanted uncial writing for literary purposes. Minuscules represent nearly 90 percent of extant NT manuscripts. (Logos Bible Software)
