Final answer:
In Ovid's story, Apollo is compared to a Gallic hound chasing a deer.
Step-by-step explanation:
Ovid draws a simile between Apollo chasing Daphne and "a Gallic hound" chasing a deer. This analogy suggests that Apollo's pursuit of Daphne is swift, relentless, and determined, similar to how a hound would chase its prey. The Gallic hound is known for its hunting ability and speed, emphasizing the intensity of Apollo's pursuit.
