Opening The Heavens

A Midsummer Tempest, iii.

Through Shelgrave's telescope, Rupert sees Jovian moons and Lunar mountains:

"'I can forgive you much, Sir Malachi, for that you've opened heavens up to me.'" (p. 20)

When Munan Eyvindson from Iceland (Manson Everard of the Time Patrol) visits the Holy Roman Emperor, Frederick II:

"Not just the gift he brought caught the emperor's fancy. Still more did the sagas he could relate, the Eddic and skaldic poems. 'You open another whole universe!' Frederick exulted."
-Poul Anderson, The Shield Of Time (New York, 1991), PART SIX, 1245alpha A. D., p. 396.

There are two kinds of universe:

the one that we inhabit, explored by scientists;
the many that we imagine, described in literature.

In Poul Anderson's works, we appreciate both.
