 Complicating matters is the directory's division into four parts, each of which likely dates from a different time.Wilhelm Sauer suggested for the third and most extensive part, which contains the mention of Mefridus de Ripoldeskirchen, the 1194-1198 dates.The authors Martin Dolch and Albrecht Greule concurred with this assessment in their 1991 work "Historisches Siedlungsnamenbuch der Pfalz", although writer Albrecht Eckhardt had reckoned its date as something more like 1189/1190 in 1976, with which Volker Rödel later agreed in 1980.
