Whilst painted by different artists for different types of patron within buildings of varying function, the Padua fresco cycles maintain a unity of style and content. Within the artistic narrative that unfolds in this sequence of frescoes, the different cycles reveal both diversity and mutual coherence. Criterion (ii): The Padua fresco cycles illustrate the important interchange of ideas which existed between leading figures in the worlds of science, literature and the visual arts in the pre-humanist climate of Padua in the early 14th century. All components retain authentic evidence of the fresco cycles, the material support on which the frescoes are painted, the plaster surfaces, the pigments and binding agents used in fresco work, and the paints themselves. The Padua fresco cycles are still fully legible, and the iconography used within them can be identified as authentic works of known 14th century artists.
