The chapter analyses the way the mnemonic images translate onto the painted surface, with a special regard for the role of imagination in both this process and the onlooker''s response to its result. The conceptual horizon of the analysis is derived from Cicero''s distinction between natural and artificial memory.
The particular material under analysis consists in the Buon governo frescoes and the Allegory of Redemption by the Sienese painter Ambrogio Lorenzetti.
