Parallel - Visage as a Standing Pool or Pond

Shakespeare:

"There are a sort of men whose visages
Do cream and mantle like a standing pond,"
The Merchant of Venice 1.1.88-89

Bacon: "Will you be a standing pool that spendeth and choketh his spring within itself?"
   Gesta Grayorum  (Spedding 8.339)

Cockburn comment: In these excerpts a man or his face is likened to a "standing pool" or a "standing pond" - a far from obvious metaphor.
