Based on stories from the Golden Legend, this is considered to be a Renaissance masterpiece. Inspired by The Lives of the Saints from the 13th-century book by Jacobo da Varagine this is Piero's most extensive work.
The story of the True Cross is the story of the rediscovery of the Cross of Christ and its return to Jerusalem in
the year 615. In this cycle of ten frescoes, Piero has depicted the biblical rulers
as political figures of the day.
At the time when the True Cross was painted this
gave the series a greater modern political edge. The Dream of Constantine is
remarkable. (Detail of a fresco; the church of San Francesco, Arezzo).
It is the first night scene to have been painted by an Italian
artist. Light as the subject of a work of art had not been explored by anyone
before Piero’s remarkable work. The artist moved to Rome and painted frescos in the Santa Maria Maggiore but these works, and his Vatican City paintings have been destroyed.
