The Bull's Head Rhyton (1600-1450 BC) has a CONCAVE CRYSTAL backing behind the left eye that magnifies the pupil, creating a 'following gaze' effect that works 3,500 years later. Only the LEFT HALF is original — the right side and horns are 20th-century reconstruction. Head to the Knossos collection galleries (look for signs to 'Bull's Head Rhyton' or 'Little Palace treasures'). Stand directly in front, look into its left eye, then step left and right. Watch the eye follow you across the room. Some Bronze Age artisan understood concave lens optics 3,200 years before we 'invented' them. Notice the dual-hole system: small hole at neck for FILLING with wine, opening at NOSTRILS for POURING libations during sacred Minoan ceremonies.
🔄 BACKUP: If you can't find it by name, ask any museum guard 'Bull's Head Rhyton?' They'll point you there — it's one of the museum's most famous pieces.
