“Sulis’s themes are water, healing, sun, blessings, wishes, community and offerings. Her symbols are water, wheat cakes and fire. The Celtic Goddess Sulis oversees all sacred wells and springs, which give healing and other blessings to those who pray at them. She also has associations with the sun, which explains the ever-burning fires in Her temples.
One hundred miles outside of London, Sulis’s ancient natural springs lie as they did for over seven thousand years until they were discovered by the Romans, who used them for ritual, wish magic, socialization and healing. The Festival at Bath revels in this region’s history, especially Sulis’s hot springs, which continue to bring thousands of visitors here annually, few of whom know that the springs are ten thousand years old and part of Sulis’s spirit. To my mind this equates with enjoying time in a hot tub or sauna (perhaps you can take part of the day at a local spa).
If a spa isn’t possible, let your bathroom get really steamy from a hot-water shower, then sit inside for awhile absorbing Sulis’s cleansing power into your pores. Release you tensions and dis-ease to Her. Maybe light a candle to represent Sulis’s presence with you, and meditate as you relax. Remember, the bathroom is one of the few places you can be assured of a private moment with the Goddess, so take advantage of it!”
(Patricia Telesco, “365 Goddess: a daily guide to the magic and inspiration of the goddess”.)
“The Goddess of the hot springs at Bath, England (the only hot springs in Britain), Sulis’s name come from a root meaning ‘eye’ or ‘gap’, referring both to the spring from where half a million gallons of hot water still well up every day, as well as to Her powers as seeress.
Her hot spring has been renowned for its healing powers since ancient times, and when the Romans arrived in Britain they built a bath complex around the spring, and named the place Aquae Sulis (‘the Waters of Sulis’). Pilgrims came from mainland Europe to bathe in the therapeutic waters, and references to Sulis are known from as far away as Germany.
The Romans equated Sulis with their Minerva, and so She was known to them as Sulis Minerva–which is somewhat unusual, since the Romans generally used the native Celtic deity name after the Roman name. This is taken as an indication of Her importance and fame.
Though famous for healing, Sulis could curse as well as cure, and in Bath many ‘curse tablets’ have been found, asking Her to punish people suspected of wrongdoing.
She is shown here with one of the small offering-pans dedicated to Her by worshippers which were found at the site of Bath; they were usually inscribed ‘DSM’, short for the Latin Dea Sulis Minerva, ‘to the Goddess Sulis Minerva’. Her dress is the same milky greeny-grey as the water of the springs, and Her hair is the bright orange of the deposits left by the mineral-rich waters.” 
According to Patricia Monaghan, “the ancient British Goddess of the healing waters had Her special shrine at the spa we call Bath, where Her power was strongest. Some scholars say that She was a solar divinity, deriving Her name from the word that means ‘sun’ and ‘eye’. This interpretation may account for the perpetual fires at Her shrines; in fact that Her springs were hot, rather than cold, is additional evidence in favor of considering Her a sun Goddess.
She was honored into historic times; the Roman occupiers called Her Minerva Medica (‘healing Minerva’); occasionally She is called Sulivia.
In statuary and bas-reliefs, She was shown as a matronly woman in heavy garments with a hat made of a bear’s head and Her foot resting on a fat little owl. In Bath and on the continent, She also appears in multiple form, as the tripartite Suliviae. The latter name is also used of the pan-Celtic divinity Brigid, suggesting a connection between these figures” (p. 286 – 287).
Sulis’s name is also seen as Suliviae, Sulivia, Sul, Sulei, and Sulla.
