The fox has many tricks, and the hedgehog only one, but that is the best of all

The fox knows many things - the hedgehog, one big one

The fox has many tricks. The hedgehog has but one. But that is the best of all.

πόλλ' οἶδ' ἀλώπηξ, ἐχῖνος δ'ἓν μέγα

I'm an inveterate fox and not a hedgehog, so I always think you should try everything.

And by a prudent flight and cunning save A life which valour could not, from the grave. A better buckler I can soon regain, But who can get another life again?
