In 1912, Thomas Hardy wrote a poem for the Titanic Disaster Fund, a matinee given at Covent Garden following the catastrophic sinking of RMS Titanic a month earlier. The Convergence of the Twain, is written in that slightly bleak, ironic style that Hardy excels in, though not all found the poem satisfactory.  

As the poet imagines it, the ship and the iceberg are created at the same time, as if destined for their ultimate 'convergence.'

    'For as the smart ship grew

    In stature, grace and hue

In shadowy silent distance grew the Iceberg too.'

It was from Hardy's poem about the Titanic that I got the idea for the poem in the previous post (poor as it is compared to the master) that would reflect upon the demise of the Titan, in the very same spot that iceberg and ship once collided.

Trine is my best guess at three, as twain is for two.
