The complexity of Shakespeare's poetry is always astonishing. It seems that with every reading, more is revealed. Some have found the demands placed on them as readers to be excessive. It can be hard work, granted. But always, the effort proves to be worthwhile. In other words, what we eventually will find in the convoluted syntax and dazzling rhetoric is wisdom and beauty. Something else we have to keep in mind: serious artists work at their crafts very hard and very often. They are not interested in repeating themselves. We therefore shouldn't be surprised if we have to do some background labour to keep up - using glossaries, references, criticism, and so on. Here's another excerpt from Antony and Cleopatra. Here, a messenger is notifying Octavius that Sextus Pompeius (Pompey), the son of the late Gnaeus Pompeius, a member of the first triumvirate (with Crassus and Julius Caesar), is rapidly gaining popularity and therefore strength in his naval powers. Caesar's response regarding the vagaries of popularity is remarkable both in style and content:

MESSENGER

... Pompey is strong at sea;

And it appears he is beloved of those

That only have fear'd Caesar: to the ports

The discontents repair, and men's reports

Give him much wrong'd.

OCTAVIUS

I should have known no less.

It hath been taught us from the primal state,

That he which is was wish'd until he were;

And the ebb'd man, ne'er loved till ne'er worth love,

Comes dear'd by being lack'd. This common body,

Like to a vagabond flag upon the stream,

Goes to and back, lackeying the varying tide,

To rot itself with motion.
