Some errors were caused by sight.
- Permutation: Letters which resemble one another can be difficult to distinguish, especially when reading someone else’s hand writing. In this error the copies sees one letter and mistakes it for another.
- Dittography is when a word or group of words is picked up a second time by the scribe and as a result the same line is copied twice when it only appears once.
- Haplography is the opposite of Dittography. It occurs when a text is missing a line owing to the fact that two lines have a similar ending. The copiest sees the second line, mistakes it for the one he’s already copied and moves on to the third.
Others are caused by hearing.
It is easy for someone with perfect hearing to hear incorrectly when words are confused because of similarly sounding letters. The scriptorium—the ancient “copy center”—worked by having one person dictate to a group of scribes who produced the copied manuscripts. Even when a scribe copied a manuscript alone, he would have read a portion out loud and then written it down. During the time from reading a text to writing it down, errors are bound to happen. Writing down something that sounds the same as that which was read is a common error that is detectable.
And still others were caused by lapses in memory. You read one thing but in between reading the

- Variations of Sequence
- Transposition of Letters
- Assimilation of Wording
Intentional Errors
“They write down not what they find but what they think is the meaning; and while they attempt to rectify the errors of others, they merely expose their own.” (Jerome, Epist. lxxi.5, Ad Lucinum concerning scribes copying his own works.).
