Analysis of Roundel

Now welcome Summer with thy sunne soft,
That hast this winter`s weathers overshake,
And driven away the longe nighties black.

Saint Valentine, that art full high aloft,
Thus singen smalle fowles for thy sake:
Now welcome Summer with tye sunne soft,
That hast this winter`s weathers overshake.

Well have they cause for to gladden oft,
Wince each of them recovered hath his make.
Full blissful may they singe when they wake:
Now welcome Summer with they sunne soft,
That has this winters weathers overshake,
And driven away the longe nighties black.
