"Poussin Teniers...."

The Shepherds. What is the mystery that Poussin and Teniers hold? Think of one obvious word to describe each painting. Some researchers say that "No Temptation" refers to the Teniers St. Anthony that is NOT a "Temptation of St. Anthony". Whatever St. Anthony one sees, the word that comes to mind is "CAVE". This is the "Shepherds of Arcadia II" by Poussin, the word is the subject of the painting and that word is "TOMB". Together the Teniers and the Poussin could point to a "CAVE - TOMB".
