King Lear -- IV. 6.
Could great men thunder
As Jove himself does, Jove would ne'er be quiet,
For every pelting, petty officer
Would use his heaven for thunder: nothing but thunder--
Merciful heaven!
Thou rather, with thy sharp and sulphurous bolt,
Splitt'st the unwedgeable and gnarled oak,
Than the soft myrtle!--O, but man, proud man!
Drest in a little brief authority --
Most ignorant of what he's most assured,
His glassy essence,--like an angry ape,
Plays such fantastic tricks before high heaven,
As make the angels weep.
