You give your cheks a rosy stain,
With washes dye your hair;
But paint and washes both are vain
To give a youthful air.

Those wrinkles mock your daily toil,
No labor will efface 'em,
You wear a mask of smoothest oil,
Yet still with ease we trace 'em.

An art so fruitless then forsake,
Which though you much excel in,
You never can contrive to make
Old Hecuba young Helen.

William Cowper
