Naval records seem an unlikely source of information about musicians, but many unlikely things happened in Venice. It has recently come to light that Venetian craft guilds served as conscription agencies for the Armada and revenue agencies for the Republic. Hence, one of the things that is to be found among naval records in the Venetian State Archives is a series of reports from the instrumentalists’ guild (‘arte di sonadori’) concerning its membership. The surviving documents relate principally to the period from 1672 to 1727, although the alliance of guild and government was operative for several centuries. The reports of membership are notably lengthy (guild membership seems to have been on average about 170) and frequently include members’ ages, knowledge of which was vital to estimates of potential naval strength. In the following pages the reader will find an annotated listing of names and ages representing the contents of the seven membership lists in the fascicle labelled ‘Sonadori’ in Bus ta 553 of the archival source ‘Milizia da Mar’. No corresponding records of a guild of ‘cantori’ have come to light.
