 After a month, the altarpiece-makers gathered in said church and there they showed their drawings, their devised design and their work and payment conditions to the clergy and butlers of the parish church.These men chose one of these offers, then showed it to all the contestants to commence the bidding.That auction lasted the time that a candle takes to consume (although some times it was three candles' time), and the job was given to the master whose bid was on top at that moment.
