Dietisalvi di Speme

In 1262 he painted a now lost gonfalon, a civic processional heraldic flag or banner, for the Terzo di San Martino, one of the three main territorial divisions of the city of Siena in the Middle Ages.

These various documents consistently give only his first name, Dietisalvi, and the quasi-surname di Speme appears only on a single occasion, in a record of 18 January 1290 (which according to Sienese usage was styled 1289).

These works display a gradual distancing from the influence of Coppo di Marcovaldo, and a movement towards more substantial depiction of bodies and a greater attention to colour.

In addition, Dietisalvi is credited with the outer doors on the reliquary of Blessed Andrea Gallerani (in the Pinacoteca Nazionale (National Gallery) of Siena, inv.

The final part of Dietisalvi's career is associated with the cross preserved in Siena’s Museo delle pie disposizioni (Museum of Pious Bequests), which seems to be influenced by the Maestà, then a recent work of Cimabue.
