The procedure was to select by lot twelve consuls from the twelve major guilds
and fifty-five citizens whose names had been approved on the occasion of earlier
scrutinies for different offices (the Priorate, the twelve Buoni Huomini, the
Gonfalonieri). These sixty-seven persons designated by lot subsequently chose the
100 electors
(arrotti) who voted in the scrutiny. On the composition of the body
that carried out the squittinio in the fourteenth century, see Najemy,
Corporatism
and Consensus, p. 122.
