The Uffizi Fortitude page records the 1470 Mercanzia commission.

Context

Shared Pollaiuolo cycle remains. Justice allegory is not a modern court reform.

Sandro Botticelli’s documented role is bounded by other offices and collaborators named in the sources below.

Uffizi dates Fortitude 1470 for the Tribunale di Mercanzia virtues series otherwise by Pollaiuolo’s workshop. Tommaso Soderini’s intervention is the received Medici-faction neighbourhood. Later Uffizi tickets are not the 1470 act.
