What the thing is
Fresco is a mural painting technique applied exclusively to freshly laid wet lime plaster.
Where it came from
It emerged in the Aegean during the Bronze Age (c. 1640–1600 BC), with earlier examples in Egypt (c. 3500–3200 BC).
What it gets right
It fixes colour permanently into stone and lime. The chemical bond between pigment and carbonating plaster makes the image inseparable from the wall.
What it gets wrong
It is routinely misapplied in English to all wall painting—ignoring the strict technical requirement of wet intonaco and no binder.
Why it matters now
It reveals how material constraints shape cultural endurance: a method built on timing, chemistry, and irreversible integration resists digital replication and aesthetic trend.
Is it worth your time
Yes—if you need to understand how pigment becomes architecture, or why some wall paintings survive millennia while others vanish in decades.
