excerpt from I. The Initial Love in "Initial, Daemonic and Celestial Love" by Ralph Waldo Emerson

Ralph Waldo Emerson believed that true transcendence was rooted in nature and the liberation of the spirit from the laws of man and the church. In his three-part poem, each segment represents the forces that either liberate or imprison the human spirit.

…I must end my true report,
Painting him from head to foot,
In as far as I took note,
Trusting well the matchless power
Of this young-eyed emperor
Will clear his fame from every cloud
With the bards and with the crowd.

He is wilful, mutable,
Shy, untamed, inscrutable,
Swifter-fashioned than the fairies.
Substance mixed of pure contraries;
His vice some elder virtue's token,
And his good is evil-spoken.
Failing sometimes of his own,
He is headstrong and alone;
He affects the wood and wild,
Like a flower-hunting child;
Buries himself in summer waves,
In trees, with beasts, in mines and caves,
Loves nature like a hornèd cow,
Bird, or deer, or caribou.

Shun him, nymphs, on the fleet horses!
He has a total world of wit;
O how wise are his discourses!
But he is the arch-hypocrite,
And, through all science and all art,
Seeks alone his counterpart.
He is a Pundit of the East,
He is an augur and a priest,
And his soul will melt in prayer,
But word and wisdom is a snare;
Corrupted by the present toy
He follows joy, and only joy.
There is no mask but he will wear;
He invented oaths to swear;
He paints, he carves, he chants, he prays,
And holds all stars in his embrace.
He takes a sovran privilege
Not allowed to any liege;
For Cupid goes behind all law,
And right into himself does draw;
For he is sovereignly allied,—
Heaven's oldest blood flows in his side,—
And interchangeably at one
With every king on every throne,
That no god dare say him nay,
Or see the fault, or seen betray;
He has the Muses by the heart,
And the stern Parcae on his part.
What is the connotative meaning of the word mask from the line "There is no mask but he will wear;"?

an article of clothing

an intentional lie
an assumed identity

a covering for the face
