You know Macbeth is going to be one serious bloke when he's compared to lions and eagles:
King – Dismayed not this
Our Captains, Macbeth and Banquo?
Captain - Yes –
As sparrows, eagles, or the hare, the lion.
If I say sooth I must report they were
As cannons overcharged with double cracks;
Doubly redoubled strokes upon the foe.
(Macbeth, Act 1, Scene 2, lines 34 - 41)
It's all downhill from there for poor old Macbeth, but he starts off well.
The stone above has nothing to do with Macbeth, really, but it's from Scotland - the Clach an Tiompain (The Eagle Stone). I don't know if it comes out clearly on the photo, but the Picts have carved an eagle into the bottom of the stone.
