When Easter falls in our lady's lap,
Then let England beware a rap.

Easter falls on March 25, when the Sunday letter is G, and the golden
number 5, 13, or 16. As in the late years, 1459,1638,1649.

1459, King Henry VI. was deposed and murdered.
1638, The Scottish troubles began, on which ensued the great
rebellion.
1648-9, King Charles I. murdered.

I think it will not happen so again till the year 1991.

Now for epilogue and remarkable reflection.

Turning over our annals, I chanced upon a two-fold circumstance: I
will not say, that none else hath observed the same; but I protest,
("Ita, me Deus amet, ut verum loquor") I do not know of any that have;
and therefore must justly claim to be acquitted from the least
suspicion of plagiarism, or plowing with others heifers.

The first is, of William the Conqueror. The second, of Edward III.
(I need not say any thing of the eminency of these two; every one
knows what great things they did.) And making reflection upon the
auspicious birth-day of His Royal Highness the Duke of York, I
adventured upon the following composure. (I cannot be proud of my
poetry; but I cannot but be glad of my Bon Heur, "d'avoir (en lisant)
tombe si fortuement sur les evenements d'un si Bon Jour".)
