Both champions, belted tight, stepped into the ring
and grappling each other hard with big burly arms,
locked like rafters a master builder bolts together,
slanting into a pitched roof to fight the ripping winds.
– Homer
The Iliad, Book 23, lines 791-794. This is a beautiful epic simile description of Great Ajax and Odysseus wresting for a prize, with their hands gripping each other as tight as rafters bolted together by a master builder.
