Bull Relief Fresco
Visit the ruins of the North Entrance of Knossos and you'll see the famous Bull Relief Fresco. It's a rare example of three-dimensional plaster technique from Minoan Crete, and it dates from the Late Minoan II, or Mycenaean, phase of the Palace. In ancient times, the North Entrance was a sloping, narrow passage leading into the North Pillar Halls. There might have been an identical fresco on the opposite wall, so that visitors passed between two high-relief bulls.
Most of the bull motifs associated with Knossos, including the famous Toreador Fresco, date from this late, Mycenaean period.
Interesting anecdote: when workers first excavated the Bull Relief Fresco a century, they were so startled by the realistic, charging bull image that they initially thought they had awakened a demon, or the Devil himself.
