Madam, there is alighted at your gate

Madam, there is alighted at your gate
A young Venetian, one that comes before
To signify th' approaching of his lord,
From whom he bringeth sensible regreets;
To wit (besides commends and courteous breath),
Gifts of rich value; yet I have not seen
So likely an ambassador of love.
A day in April never came so sweet,
To show how costly summer was at hand,
As this fore-spurrer comes before his lord.
