Flavio Biondo's "Roma Triumphans" (1459) claimed the ancient Roman triumph, divested of its pagan rites, as a rightful inheritance of Holy Roman Emperors. Italian poet Petrarch's "Triumphs" ("I triomfi") represented the triumphal themes and biographies of ancient Roman texts as ideals for cultured, virtuous rule; it was influential and widely read. Andrea Mantegna's series of large paintings on the "Triumphs of Caesar" (1484–92, now Hampton Court Palace) became immediately famous and was endlessly copied in print form. The "Triumphal Procession" commissioned by Holy Roman Emperor Maximilian I (1512–19) from a group of artists including Albrecht Dürer was a series of woodcuts of an imaginary triumph of his own that could be hung as a frieze long.
