The Pomegranate Cups of the Three of Cups, represents the fruit Persephone ate in the realms of Pluto (Hades), thereby allowing him to hold her in the lower world even after the most powerful influence was brought to bear. There is a subtle message here, that the good things in life should be enjoyed, but with a level of distrust.
In the Thoth Deck, The Three of Cups represents Binah (All Mother) in the suit of Water and is the the card of Demeter or Persephone. Binah is symbolized by the calm dark Sea, from which arises a multi-bloomed single Lotus (many states of the One Goddess) that fills the Cups to overflowing. Being the Spiritual basis of Fertility, this card is the fulfillment of the Will of Love in abounding joy.
The Three of Cups zodiacal reference is the influence of Mercury in Cancer. Mercury, is the Will or Word of the All Father, and here it is descending on the most receptive of Signs---Cancer
However, the mysterious ideas brought about by this card abound, as Binah, the Great Sea of Life, is also the Moon in one aspect and Saturn in another; and Mercury is also known as the guide to the souls of the dead.. Needless to say, this card requires great subtlety of interpretation.
If thrown during a reading it is enough to know that the Three of Cups-Abundance, represents; plenty, hospitality,eating, drinking,pleasure, dancing, new clothes and merriment. Abundance, plenty, success, sensuality, passive success,good luck and fortune. This card reminds me of the God of Wine, Bacchus, who engages in all the above in a bounty of food and wine....and suffering the hang-over the next day. The observant Reader should caution the Querent, that although great abundance is available, and to be enjoyed; try not to over do it.
