The Ancient Mariner would not have taken so well if it had been called The Old Sailor.

It is an ancient mariner, / And he stoppeth one of three.

An orphans curse would drag to hell
A spirit from on high;
But oh! How more horrible that that
Is the curse in a dead man’s eye!

There's many a good tune played on an old fiddle.

I'll make the fur / Fly round the ears of the old cur.

An open mind is all very well in its way, but it ought not to be so open that there is no keeping anything in or out of it. It should be capable of shutting its doors sometimes, or it may be found a little draughty.
