Based on the epic simile, how should the reader picture the beam of wood Odysseus found in the cave?

Here are the means I though would serve my turn:

a club, or staff, lay there along the fold-

an olive tree, felled green and left to season

for Cyclops' hand. And it was like a mast

a lugger of twenty oars, board in the beam-

a deep-sea-going craft-might carry:

so long, so big around, it seemed.
