Alcuin of York (735-804) Carmina (song) XCIV on Punctuation or "Pointing" a Text when Making Scribal Copies
Per cola distinguant proprios et commata sensus <Let them analyse the correct meaning according to cola and commata,>
et puncts ponant ordine quosque suo, <and let them insert those relevant marks of punctuation in their proper hierarchy,>
nel vel falsa legat taceat vel forte repente <so that the lector [reader] may neither misread, nor by chance fall silent suddenly>
anti pios fratres lector in ecclesia. <before the devout brothers in church.>
