WHAT IS THE FIGURATIVE LANGUAGE IN THIS STANZA/PARAGRAPH?

All the gales
had ceased, blown out, and with an offshore breeze
we launched again, stepping the mast and sail,
to make for the open sea. Astern of us
the island coastline faded, and no land
showed anywhere, but only sea and heaven,
when Zeus Cronion piled a thunderhead
above the ship, while gloom spread on the ocean.
We held our course, but briefly. Then the squall
struck whining from the west, with gale force, breaking
both forestays, and the mast came toppling aft
along the ship’s length, so the running rigging
showered into the bilge.
