That early modern scribes had ways of correcting mistakes in their texts?
This excerpt from the Baxters book, dated 28 October 1558, records that William Sagis was admitted as an apprentice to Duncan Kenloquhy, and that he paid 6s 8d to the altar of St Tobert, as was traditional. In the sixth line from the top, you can see that the Baxters’ scribe, chaplain Peter Lawson, forgot to record that Sagis also gave a pound of wax to the altar, and so added a column of three small circles in the appropriate place in the sentence, to mark where this information should have been included. He then wrote ‘and ane pund of vax’ in the margin, following a corresponding set of three circles there.
This form of insertion was common, and can be found in the other craft books as well. In the seventeenth century, the Hammermen’s scribe used a caret (^) instead of three circles to perform the same function.
