ASTROLOGY - MONTHS OF THE YEAR - MAY The month of May, from the series by John Leighton, The Life of Man, 1866. The twelve signs (in this case Taurus) are associated with each of the months during which the Sun is in this zodiac sign. A distinctive stage in the twelve stages of Man's life is also linked with the image - in this case, May is linked with the 'Man and Father'. By the fifth month of the year, the winged hour-glass is running well. Note the signs of the festivities of the Month - the maypole in the background, the leaping lambs, and so on.
