A Seascape from Tasso

From Creation of the World, lines 675-689:

A gentle wind blows; a placid breeze, sweetly
murmuring, whispers and wanders about,
and ripples the waves, which look like
foamy silver among the rocks or by the
curved coasts; often with the color of shiny
sapphires the sea is tinged, and like
pyrope under the sun’s gentle rays.
Scattered sails fan out far away,
shining white in hundreds, in thousands,
faster than running horses and chariots;
painted ships unfold their old, famous
ensigns, and with pointed rostra furrow
their flat ways; all around, the wet fish
thrash, and often the swift dolphins 
show off their hunched backs in the air.
