As a huge oak goes down
at a stroke from Father Zeus, ripped up by the roots
and a grim reek of sulphur bursts forth from the trunk
and a passerby too close, looking on, loses courage –
the bolt of mighty Zeus is hell on earth – so in a flash,
for all his fighting power, Hector plunged in the dust,
his spear dropped from his fist, shield and helmet
crushing in on him, bronze gear clashing round him.

– Homer

The Iliad, Book 14, lines 489-496. Great Ajax seizes a rock and heaves it at Hector’s chest and knocks him down. Homer in one of his epic similes paints an image of a giant oak tree felled by a bolt of lightning from Zeus.
