Notaries Were Useful in a Contractual Society
(p. 111) Notaries were not figures of great dignity, but in a contractual and intensely litigious culture, they were legion. The Florentine notary Lapo Mazzei describes six or seven hundred of them crowded into (p. 112) the town hall, carrying under their arms bundles of documents, " each folder thick as half a bible." Their knowledge of the law enabled them to draw up local regulations, arrange village elections, compose letters of complaint. Town officials who were meant to administer justice often had no clue how to proceed; the notaries would whisper in their ears what they were meant to say and would write the necessary documents. They were useful people to have around.
