The circular shape of the wreath is intended to symbolise eternal life and Jonson symbolises his eternal love for Celia with a wreath of roses.
Drink to me only with thine eyes,
         And I will pledge with mine;
Or leave a kiss but in the cup,
         And I’ll not look for wine.
The thirst that from the soul doth rise
         Doth ask a drink divine;
But might I of Jove’s nectar sup,
         I would not change for thine.
I sent thee late a rosy wreath,
         Not so much honouring thee
As giving it a hope, that there
         It could not withered be.
But thou thereon didst only breathe,
         And sent’st it back to me;
Since when it grows, and smells, I swear,
         Not of itself, but thee.
By Ben Jonson (1572-1637)
