In the Four of Wands, we see two dancers, followed by a joyous troupe of people, leave a castle for a flower-garlanded bower. This is a card of celebration, joy, openness, and freedom; the citizens of the fortress have chosen of their own free will to come forth into the sunshine - the card can be seen as a parallel of The Tower. Here, though, rather than allowing the castle to become their prison, the people have left it of their own accord, carried along by hope, trust, and the will to celebrate the bounty that life has to offer.
