For a time, he wrote for and edited Pennsylvania Magazine: Or American Monthly Museum. It was in that periodical that, under the pseudonym "Atlanticus," Paine published the poem "The Liberty Tree, A Song Written Early in the American Revolution":
In a chariot of light from the regions of day,
The Goddess of Liberty came;
Ten thousand celestials directed the way,
And hither conducted the dame.
A fair budding branch from the gardens above,
Where millions with millions agree,
She brought in her hand as a pledge of her love,
And the plant she named Liberty Tree.
Though this tree came from overseas, it flourished "like a native." To its "peaceable shore" flocked many other nations. These people supplied "timber and tar" to "Old England" and fought on that nation's behalf "for the honor of Liberty Tree." But then:
...But hear, O ye swains, 'tis a tale most profane,
How all the tyrannical powers,
Kings, Commons and Lords, are uniting amain,
To cut down this guardian of ours;
From the east to the west blow the trumpet to arms,
Through the land let the sound of it flee,
Let the far and the near, all unite with a cheer,
In defense of our Liberty Tree.
Today, some celebrate January 29 as "Thomas Paine Day" or "Freethinkers Day."
