The biographical index for the regesta is a further part of the commentary on Melanchthon’s correspondence. The biographical information serves primarily to aid the understanding of Melanchthon’s correspondence. There is a complete list of the cross connections in this corpus, in particular among the family members. A very short character description is provided for easy orientation before the date of birth of those persons mentioned only occasionally in the volumes of letters. The short biography for those persons who are well-known and dealt with in many lexica has been kept very brief and is limited to data pertaining to their life. Works have only been quoted if they are of significance for the mention of the author in the volumes of Melanchthon’s correspondence. The exact verification can be found in the sources given in the text volumes.
