Final answer:
Odysseus shows his mastery of the bow by examining, stringing, and testing it with ease, creating a clear, sharp sound akin to a swallow's cry.
Step-by-step explanation:
In Homer's The Odyssey, Odysseus demonstrates his mastery of the bow by handling it with ease, much like a skilled musician would with a lyre.
He inspects the bow meticulously, ensuring it is in good condition, then strings it effortlessly, likened to the simple task of tuning a musical instrument for a seasoned performer.
Once the bow is strung, he tests the string with a deft touch, resulting in a sound that is clear and sharp, a testament to both his proficiency and the quality of the bow which responds with precision, akin to a swallow's cry.
