“Spes’ themes are thankfulness, hope, abundance and harvest. Her symbols are a bouquet of flowers. In Roman tradition, this Goddess’s name means ‘hope’. She joins us today to celebrate the successful harvest and keep our hearts hopeful as the earth’s plenty wanes. In art, Spes often appears as a simple bundle of flowers whose beauty inspires the most distraught of spirits.
Follow pilgrim tradition and set aside time today to thank the Goddess for Her blessings in any way that seems suited to your path and vision. For example, give Spes an offering of the first slice of holiday bread, share food with those in need, or perhaps treat the birds and squirrels in your neighborhood to some bread and nuts.
Locally we invite any friends who have no family nearby to join with us in a delightful symbolic meal. Serve round rye bread and dill dip for unity and kinship, sweet potatoes for life’s sweetness and Spes’s harvest energies, cranberries mixed with oranges to keep our energy and health intact, vegetables for firm foundations, and pumpkin pie with magical sigils carved in the crust for the Goddess’s protective spark. If you look at your own traditional menu, I’ll bet you will find many other foods and beverages that have similar symbolism to bring meaning and Spes’s magic to your table for this holiday. As you eat, remember to pass all the food and beverages clockwise to invoke Spes’s ongoing providence.”

Patricia Monaghan told us that Spes was “an early Cretan Goddess called Elphis in Greece. She was the one force left in the box of Pandora after evil had escaped into the world. Spes was ruler of the Underworld and of death’s cousin, sleep; Her plant was the poppy, but otherwise nothing is known of Her legends and meaning. In Greece and Rome, Spes became the personification of hope, worshiped in temples dedicated to Her as early as the fourth century B.C.E.” ( p. 285).
On theodora.com, it states that “Spes, in Roman mythology, the personification of Hope. Originally a nature Goddess (like Venus the garden Goddess, with whom She was sometimes identified *), She represented at first the hope of fruitful gardens and fields, then of abundant offspring, and lastly of prosperity to come and good fortune in general, being hence invoked on birthdays and at weddings. Of Her numerous temples at Rome, the most ancient was appropriately in the forum olitorium (vegetable market), built during the first Punic War, and since that time twice burnt down and restored.
The day of its dedication (August 1) corresponded with the birthday of Claudius, which explains the frequent occurrence of Spes on the coins of that emperor. Spes is represented as a beautiful maiden in a long light robe, lifting up Her skirt with Her left hand, and carrying in Her right a bud already closed or about to open. Sometimes She wears a garland of flowers on Her head, ears of corn and poppy-heads in Her hand, symbolical of a prosperous harvest.
Like Fortuna, with whom She is often coupled in inscriptions on Roman tombstones, She was also represented with the cornu copiae (horn of plenty).
* “See G. Wissowa, Religion and Kultus der Romer (1902), according to whom Spes was originally not a garden Goddess, but simply the divinity to whom one prayed for the fulfilment of one’s desires.”  In my opinion, that would seem to support Monaghan’s statement that “nothing is known of Her legends and meaning.” My interpretation is that She was just that – Hope – a personification of hope and “the divinity to whom one prayed for the fulfillment of desires.”
