Title: The First Strawberries (A Cherokee Story)

How was it that strawberries came into the world? Their creation is explained in this captivating Cherokee tale.

"Long ago when the world was new, the Creator made a man and a woman... They married, and for a long time they lived together and were happy."

Yet one day the couple quarreled, and the woman left the man in anger and haste. Taking pity on the repentant husband, the Sun sent raspberries first, then blueberries, then blackberries to the Earth in an attempt to stop the woman's retreat. But only the Sun's final gift of strawberries had the power to reunite the couple...and to this day, they are a reminder that "friendship and respect are as sweet as the taste of ripe, red berries."

Anna Vojtech's luminous watercolor paintings capture the beauty and simplicity of a timeless story that - like its sweet subject - is perfect for sharing.

Doubtless God could have made a better berry, but doubtless God never did.
-- William Butler

The strawberry grows underneath the Nettle, And wholesome berries thrive and ripen best
Neighbour'd by fruit of lesser quality.
-- William Shakespeare, Henry V

My lord of Ely, when I was last in Holborn, I saw good strawberries in your garden there.
-- William Shakespeare, Richard III

When as the rye reach to the chin,
And chopcherry, chopcherry ripe within,
Strawberries swimming in the cream,
And schoolboys playing in the stream,
Then O, then O , then O, my true love said,
Till that time come again,
She could not live a maid.

-- George Peele, The Old Wives Tale
