summary: In battle, Achilles repeatedly attacks Cygnus with lance, spear, and sword,
but Cygnus remains unwounded despite being unarmored or struck through armor.
Achilles tests his weapon on Menœtes, killing him, then returns to Cygnus. Unable
to wound Cygnus, Achilles overpowers him physically, throws him down, and strangles
him with the straps of his helmet. When Achilles tries to strip the defeated foe,
only armor remains; the God of the Ocean has changed Cygnus's body into a white
bird associated with his name.
