55 The sunflower symbolizes love of something superior. According to the sixteenthcentury writer Valeriano, it can refer either to the relation between earthly and celestial things or to the secret power that ties something low to something higher. This meaning derives from Ovid, Metamoiphosis, IV, 226-270, where Clytie, lover of the sun, is transformed into a flower whose devotion is apparent in the way it follows the sun through its daily course.

The way in which individuals in the fifteenth century used the devices of other, more powerful families is not clear. There is some evidence that permission was needed to use the device of another family. On the other hand, there are instances when the patent was either not given or does not survive. See

In a vault executed slightly after the Scala vaults, in the villa of the Del Tovaglia family in Florence, there are Gonzaga and Este devices. While Agnolo Del Tovaglia was granted the right to use the Gonzaga device, there is no extant patent from the Este. See

Scala uses not only his own device and that of the Medici, but also a purely symbolic device, the sunflower, to clarify the patron/client relationship. This would conform to the findings of Ames-Lewis, Library, and ibid., “Early Medici Devices, “Joumalofthe Warburg and Courtauld Institutes, 43 (1979), 127-30. According to him, devices which in the first half of the fifteenth century generally had little or no symbolic meaning began to be more personal and to have specific meanings under Lorenzo de'Medici. On Lorenzo's devices, see
