This sculpture portrays the denouement of the poem Tam O’Shanter by Robert Burns.  Tam is mounted on his grey mare Meg and is being chased by a young witch.  We see that the witch has just caught up with Tam and has grabbed his horse from behind…

….Now, do thy speedy utmost, Meg,

And win the key-stane o’ the brig;

There at them thou thy tail may toss,

A running stream they dare na cross. [witches and water don’t mix]

But ere the key-stane she could make,

The feint a tail she had to shake!

For Nannie, far before the rest,

Hard upon noble Maggie prest,

And flew at Tam wi’ furious ettle;

But little wist she Maggie’s mettle –

Ae spring brought off her master hale,

But left behind her ain gray tail;

The carlin claught her by the rump,

And left poor Maggie scarce a stump…

You can read the complete poem in its original form along with an easy English translation here.  Unfortunately, I am having difficulty finding information on the sculpture or artist.  If anyone knows more about it, please share!  Thanks ~
