Answer:
"When he was a baby, his mother had desired to make him immortal. So she had carried him to the dark realm of the underworld, and had bathed him there in the waters of the river Styx. The water of this river had such power that whatever it touched was safe from any mortal harm forever."
Step-by-step explanation:
This sentence describes how Achilles' mother took him to the underworld and bathed him in the river Styx to make him immortal, which shows how the mythical setting of ancient Greece shaped the character of Achilles. In Greek mythology, the underworld was a realm of gods and spirits, and the river Styx was believed to have magical powers that could protect mortals from harm. The fact that Achilles was bathed in these waters as a baby highlights his divine heritage and his exceptional status as a hero, but it also foreshadows the tragic fate that awaits him, as his mortality is ultimately his undoing.
