Pietro da Cortona's "The Copper Age" is an allegorical oil on canvas from the Palazzo Pitti frescoes, depicting a period of nascent conflict and moral decay in classical mythology. The painting features a dynamic composition and a warm colour palette.

Pietro da Cortona, a leading figure of the Roman Baroque, painted "The Copper Age" as part of a series of frescoes depicting the ages of man, commissioned for the Palazzo Pitti in Florence. This work is an allegorical representation of the Copper Age, a period in classical mythology characterised by increasing violence and moral decay, following the Golden and Silver Ages. The frescoes were intended to celebrate the reign of the Medici family and to situate them within a grand historical and mythological narrative. The painting presents a scene of relative abundance and nascent conflict. Figures are shown engaging in various activities, some peaceful, such as harvesting grapes and tending to animals, while others hint at the emerging strife of the age. The composition is dynamic, with figures arranged in a complex, interwoven manner that is typical of Baroque painting. The colour palette is warm, dominated by earthy tones and highlighted by touches of blue and gold. The figures are rendered with a classical sensibility, their forms idealised and their poses graceful, yet there is also a sense of realism in their expressions and gestures.
