As I walked the porticoes of Bologna it wasn’t long before the quirky knobs and  knockers that peered out from the heavy wooden doors caught my eye.  I couldn’t help but notice the wide variety of door furniture adorning the city’s thresholds.  As I passed by entrances and doorways small human faces peered silently at me; some serene some grimacing.  Gaping keyholes awaiting heavy metal keys yawned at me.  Ornate, detailed; plain, simple all shared the purposes of announcing a visitor.   Gleaming brass reflected the sunlight or unpolished and dull faded into the wood.  Take a look – do you have a favourite?
