Final answer:
In the myth of Apollo and Hyacinthus, the phrase 'flitting life' symbolizes the short-lived and transient nature of human life, acknowledging how quickly it can be altered or ended.
Step-by-step explanation:
The phrase 'flitting life' in the context of Apollo and Hyacinthus often symbolizes the fleeting nature of human existence. In mythology, Apollo, the god of the sun, is deeply saddened by the accidental death of his beloved companion Hyacinthus. The term 'flitting' implies something that moves quickly and lightly without staying in one place for too long. This motif is representative of the transient, ephemeral nature of life, which can be cut short unexpectedly. Like the flitting movement of a butterfly, life can be short-lived, moving from one state to another, akin to the swift journey from life to death that Hyacinthus experiences.
