A-MAYING

'Queen Guinevere's Maying' - John Maler Collier

For thus it chanced one morn when all the court, 
Green-suited, but with plumes that mocked the may, 
Had been, their wont, a-maying and returned, 
That Modred still in green, all ear and eye, 
Climbed to the high top of the garden-wall 
To spy some secret scandal if he might, 

(Alfred, Lord Tennysosn -  'Idylls of the King' - 'Guinevere')
