Focus on Vertumnus (Arcimboldo) and explain the Interpretations.
The political interpretation of Vertumnus revolves around Rudolf II's rule. In the interpretation, Vertumnus acts as a statement claiming that the known world was claimed under Rudolf II and reveals his intention to defeat the Turks, not for the sake of Christianity but rather for the sake of global power and the everlasting Habsburg dynasty. Politically, Vertumnus has also been interpreted to reveal that Rudolf II's power as the Holy Roman Emperor did not only apply to his subjects and kingdom, but to nature itself (again referencing back to the god Vertumnus). There is also a poetic interpretation that was derived from Arcimboldo's piece. When Arcimboldo compared Rudolf II to Vertumnus, the emperor took on Vertumnus as a representation of himself. While Vertumnus could change his form at will, Rudolf II was known to change his moods at will, too. In Roman mythology, Vertumnus is the god of changing seasons, gardens, fruit trees, and plant growth. These aspects of Vertumnus indicate an "underlying permanence" to the god which in turn reflects back onto Rudolf II's rule. Furthermore, this particular god was present during the birth of Rome which acts as another allusion to the Holy Roman Emperor, Rudolf II.
