More rapid than eagles his coursers they came,
And he whistled, and shouted, and called them by name;
“Now, Dasher! now, Dancer! now, Prancer and Vixen!
On, Comet! on, Cupid! on, Donder and Blitzen!
To the top of the porch! to the top of the wall!
Now dash away! dash away! dash away all!”
From Clement Clarke Moore’s A Visit from St Nicholas (1823)
