Six Persons at Basel, in the Year 1529
In the year 1529, those of Basel imprisoned nine of those who were baptized according to the command of Christ; six* of whom, as they write, were banished.
They also write that at Bomburg, a castle in the dominion of Basel, some of the chief Anabaptists were imprisoned by one Bartholomew Sincken, who was castellan there. But what they finally did with them, the record does not say. Compare this with the account in the preface to the Offer boeck der Doopsgesinde, of the year 1615, letter Y, page 2.
