The history of the Evangelical churches of the valleys of Piemont : Containing a most exact geographical description of the place, and a faithfull acount of the doctrine, life, and persecutions of the ancient inhabitants. Together, with a most naked and puctual relation of the late bloudy massacre, 1655. And a narrative of all the following transactions, to the year of Our Lord, 1658. All which are justified, partly by divers ancient manuscripts and partly by other most authentick attestantions.
