Famous quotes containing the words variable and/or star:
“Walked forth to ease my pain
Along the shore of silver streaming Thames,
Whose rutty bank, the which his river hems,
Was painted all with variable flowers,”
—Edmund Spenser (1552?–1599)
“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)
