# Fortitude is completed in 1470 for the Mercanzia virtues cycle in Florence as Botticelli’s first securely dated panel

Date: 1470

## The fact

The Uffizi Fortitude page records the 1470 Mercanzia commission. Britannica independently treats Fortitude as the first securely dated masterpiece.

It is one event.

## Context

A civic virtue panel for a merchants’ tribunal is a knowledge-and-civic-image path. Shared Pollaiuolo cycle remains. Justice allegory is not a modern court reform.

[Sandro Botticelli](/people/sandro-botticelli)’s documented role is bounded by other offices and collaborators named in the sources below. Sharing a field with them is not a reason to drop a documented act, and it is not a reason to assign later consequences done in the name after death.

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.

Named person as heading of the dated public instrument. Later editors, museums, printers, or offices share publication. Complex where later carriers are the surviving public file.

## Evidence and sources

Uffizi — Botticelli, Fortitude and Britannica — Sandro Botticelli independently describe this instrument.

Official or archival record: Uffizi — Botticelli, Fortitude (https://www.uffizi.it/en/artworks/fortitude; Gallerie degli Uffizi).

## Significance

Fortitude 1470 is a knowledge-access path of high confidence on the dated panel.

## What is established and what is not

Established as a sourced public record of this instrument at the date assigned here.

What would change the picture: a contradictory original with a different date or name, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.

Established here: a sourced, dated public instrument with a named contribution by Sandro Botticelli.

They are not a public rating.

Sandro Botticelli did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. A portrait or conventional bust is not this mechanism. Allegation, reconstruction, and established occurrence stay distinct. Paintings are lifetime dated instruments; later Uffizi tickets are not. Keep the carrier date of later English distinct from the received historical year stored in the date field. Do not read a later English edition as a recovered autograph of Sandro Botticelli.
