And fear not lest existence closing your
Account, and mine, should know the like no more;
The Eternal Saki from that Bowl has poured
Millions of Bubbles like us and will pour
When you and I behind the Veil are past:
Oh but the long long while the world shall last,
Which of our coming and departure heeds
As the Sev’n Seas should heed a pebble-cast.

It was even more constantly present to the mind of Tennyson. Astronomy and Geology had been among his favourite studies from his early youth, and remained so all his life. When I was walking with him toward the Needles and looking at the magnificent chalk cliff below the downs, and spoke about his felicitous epithet for it—“the milky steep,” he said, “The most wonderful thing about that cliff is to think it was all once alive.” The allusions to it in his poems are innumerable:

There rolls the deep where grew the tree,
O earth, what changes hast thou seen!
There where the long street roars, hath been
The stillness of the central sea.

He was always “hearing the roll of the ages.” He, too, had read his Lyell, and the contemplation of geological time suggested to him exactly the same reflections which FitzGerald draws out. Indeed, it seems not unlikely that he himself may have imparted them to FitzGerald. For he has embodied just these thoughts in that noble late poem “Parnassus,” with a resemblance which is startling. But while the parallel between “Parnassus” and FitzGerald’s letter is extraordinarily close up to a certain point, the contrast, when it is reached, is even more striking, and is the fundamental contrast between the two men and their creeds:

What be those two shapes high over the sacred fountain,
Taller than all the Muses, and huger than all the mountain?
On those two known peaks they stand, ever spreading and heightening;
Poet, that evergreen laurel is blasted by more than lightning!
Look, in their deep double shadow the crown’d ones all disappearing!
Sing like a bird and be happy, nor hope for a deathless hearing!
Sounding for ever and ever? pass on! the sight confuses—
These are Astronomy and Geology, terrible Muses!

So far Tennyson agrees with Omar:

Ah make the most of what we yet may spend
Before we too into the dust descend;
Dust into dust and under dust to lie,
Sans wine, sans song, sans singer and sans end!

But then comes the divergence, conveyed with the exquisitely sympathetic change of rhythm:

If the lips were touch’d with fire from off a pure Pierian altar,
Tho’ their music here be mortal, need the singer greatly care?
Other songs for other worlds! the fire within him would not falter;
Let the golden Iliad vanish, Homer here is Homer there.

The beautiful lines which form the Envoy to “Tiresias,” already alluded to, never reached their address. I remember well, when we spoke of FitzGerald, the sadness with which Tennyson said to me, “He never saw them. He died before they were sent him.” After his death Tennyson added the Epilogue on the same note. It is touching to see that in his closing lines to his old friend he had hinted with tender delicacy at the same creed to which he always clung:
