Rubiães (Minho), Portugal

The megaphallic male on the right is not sucking wine from a barrel, but playing an instrument called the dolio.

Compare him with corbels at Santa Mariña de Esposende (Ourense),

Givrezac (Charente-Maritime),

at Béceleuf (Deux-Sèvres),

and at Arthous (Landes).

To confirm that this barrel-like object is in fact a musical instrument,
compare with the left-hand side of the doorway at Moarves (Cantabria)
which seems to be Salome and musicians at Herod's banquet.
