Final answer:
The demise of Achilles is attributed to an arrow to his heel, guided by Apollo and often credited to Paris. His vulnerability at the heel was caused by his mother's attempt to render him invulnerable. Achilles was a principal figure in Greek mythology, and his special armor and heroic death are central themes in tales connected to the Trojan War.
Step-by-step explanation:
The Greek mythological character who killed Achilles is not specifically named in the ancient texts; however, it is often stated that Achilles was killed by an arrow at the heel during the Trojan War. The arrow was guided by the god Apollo and is commonly attributed to Paris, a prince of Troy. Achilles' vulnerability—his heel—was due to his mother Thetis dipping him into the river Styx as a child to make him invulnerable, but she held him by that heel, leaving it unprotected.
Achilles was a great hero of the Greek mythology and his story is mainly told through Homer's Iliad. He possessed special armor made by Hephaestus, and after his death, a well-known dispute arose between Ajax and Odysseus over who should inherit his armor. This dispute was significant enough to be depicted on ancient Greek pottery, such as the Attic black figure amphora by Exekias, which shows images of Achilles and Ajax and indirectly mentions their fated endings through a game depicted on the vase. Ultimately, Achilles meets his end in the Trojan War and his death is famously attributed to an injury at his heel, giving rise to the term 'Achilles heel' to describe a person's point of vulnerability.
