Oh! Then farewell, thou beauteous queen! Andy Newsam (LJM Uni)

Thy sway may soften natures yet untamed,

Whose breast, bereft of the native fury,

Then shall learn the milder virtues.

We, with anxious mind, follow thy latest footsteps here,

And far as thought can carry us;

My labours now bedeck the monument for future times

Which thou at parting left us. Thy return

Posterity shall witness; years must roll away,

But then at length the splendid sight

Again shall greet our distant children’s eyes.


Sir Edmond Halley Andy Newsam (LJM Uni)1656 -1743
