Summary: 
Mention of the cave and church of arrest in the Valley of Jehoshaphat, from a guidebook compiled AD 1137.
Commentary: 

 

As Egeria (36.1-3) does not mention a cave or a church in her detailed description of the liturgy of Holy Thursday, it seems almost certain that their mention in Petrus Diaconus must have come from a later source, pace Wilkinson, p. 326.
