Dionysius and Pietro Domenico

Italian inventors who are said to have designed the first double-gate locks for a canal, built on the Brenta, near Padua, in 1481. Some authorities claim that this date is too late for the invention of multiple locks, but an extensive 1778 work on navigation attributed the invention of the canal lock, which had a water opening built into the wooden gates, to the Domenico brothers.
