Obviously I have multiple spirit animals, since all Black Magi need at least twenty animal sacrifices to be born into this world.

For a shortlist, my animals include:

A GOAT

A cat:

And Tom Cruise:

There are many metaphors of artists contributing to the canon with this general sense, but perhaps this is an echo of the way Shelley presents the spirit of Keats in Adonais:

XLII
He is made one with Nature: there is heard
His voice in all her music, from the moan
Of thunder, to the song of night’s sweet bird;
He is a presence to be felt and known
In darkness and in light, from herb and stone,
Spreading itself where'er that Power may move
Which has withdrawn his being to its own;
Which wields the world with never-wearied love,
Sustains it from beneath, and kindles it above.

XLIII.
He is a portion of the loveliness
Which once he made more lovely: he doth bear
His part, while the one Spirit’s plastic stress
Sweeps through the dull dense world, compelling there
All new successions to the forms they wear;
Torturing th' unwilling dross that checks its flight
To its own likeness, as each mass may bear;
And bursting in its beauty and its might
From trees and beasts and men into the Heaven’s light.

XLIV.
The splendours of the firmament of time
May be eclipsed, but are extinguished not;
Like stars to their appointed height they climb,
And death is a low mist which cannot blot
The brightness it may veil. When lofty thought
Lifts a young heart above its mortal lair,
And love and life contend in it, for what
Shall be its earthly doom, the dead live there
And move like winds of light on dark and stormy air.

By creating a poem, Glück is adding to the firmament of time and making the mountain of the past great poets even taller.
