What images do Duncan's words in act 1 scene 4 conjure up?

DUNCAN

Is execution done on Cawdor? Are not

Those in commission yet return'd?

DUNCAN

There's no art

To find the mind's construction in the face:

He was a gentleman on whom I built

An absolute trust.

O worthiest cousin!

The sin of my ingratitude even now

Was heavy on me: thou art so far before

That swiftest wing of recompense is slow

To overtake thee. Would thou hadst less deserved,

That the proportion both of thanks and payment

Might have been mine! only I have left to say,

More is thy due than more than all can pay.

DUNCAN

Welcome hither!

I have begun to plant thee, and will labour

To make thee full of growing. Noble Banquo,

That hast no less deserved, nor must be known

No less to have done so, let me enfold thee

And hold thee to my heart.

DUNCAN

My plenteous joys,

Wanton in fullness, seek to hide themselves

In drops of sorrow. Sons, kinsmen, thanes,

And you whose places are the nearest, know

We will establish our estate upon

Our eldest, Malcolm, whom we name hereafter

The Prince of Cumberland; which honour must

Not unaccompanied invest him only,

But signs of nobleness, like stars, shall shine

On all deservers. From hence to Inverness,

And bind us further to you.

DUNCAN

My worthy Cawdor!

DUNCAN

True, worthy Banquo; he is full so valiant,

And in his commendations I am fed;

It is a banquet to me. Let's after him,

Whose care is gone before to bid us welcome:

It is a peerless kinsman.
