he hurled a heavy lance at the great and awesome shield
and its massive surface clanged as it took the point.
Achilles had thrust it forth with his strong fist,
fearing staunch Aeneas’ spear with its long shadow
would drive its whole length lightly through his buckler –
groundless fears.
…So now not even seasoned Aeneas’ heavy shaft
could smash Achilles shield.

– Homer

The Iliad, Book 20, lines 299-304, 307-308. Aeneas hurls a heavy lance at the shield of Achilles. But the mighty shield, crafted by the god of fire, stands up to the assault and the spear cannot pierce it.
