Famous quotes containing the words variable and/or star:
“There is not so variable a thing in nature as a lady’s head-dress.”
—Joseph Addison (1672–1719)
“Find out the peaceful hermitage,
The hairy gown and mossy cell,
Where I may sit and rightly spell
Of every star that heaven doth show,
And every herb that sips the dew;
Till old experience do attain
To something like prophetic strain.
These pleasures Melancholy give,
And I with thee will choose to live.”
—John Milton (1608–1674)
