Hot and dry July (Julius) has Romans focusing on the Gods of Water. The major festival for Neptune, the God of the Waters, is held in July. Also, Apollo, as the God of Healing, has games held in his honor. Other festivals held in July include the Nonae Caprotinae (Nones of the Wild Fig) and Lucaria (Grove Clearing). (Before the calendar reforms of Julius Caesar, July was Quinctilis, the fifth month. Later it was renamed for Caesar, himself.) (The Roman Calendar)
On the advice of the Sibylline Books, Romans held games for Apollo for to ask for help in the Second Punic War (212 BCE). They had just experienced several major defeats. Then later, the games became yearly to thank Him for his help in ending a city wide plague. The Ludi Apollinares (Apolline Games) are held from July 6 to 13. They include theater performances, games, and fairs. People would wear garlands and feast at the entrances of their homes.
Apollo was first considered to be a God of Healing by the Romans. Since He was a Greek God, his temples were built outside of the official boundary of Rome. During the Empire, the Romans also considered Him to be a God of Bards and Diviners. (Sol Indiges is the Roman God of the Sun.) (God of the Month: Apollo)
The second Parilia is held on July 7. (The April Parilia is for small livestock.) The July Parilia is for sheep and cattle. Animals and their pens are cleaned out and smudged with sulfur. Pales are/is the God/s of Livestock. (God of the Month: Pales)
Also on July 7, the Nonae Caprotinae is held. Traditionally, offerings of figs were given to Juno Caprotina under the wild fig (caprificus). This is to honor Her as the Goddess of Serving Women. In modern times, it can be celebrated by giving figs in Juno Caprotina’s name to service workers.
Silvanus and the Forest Gods
Lucaria, the Festival of the Grove, is held on July 19 and 21. Traditionally, the Romans would clear land or thin woods at this time. They made offerings of a pig to Silvanus and the Forest Gods for permission to clear wood. Lucaria also included votives of works of arts placed in the standing groves. On these two days, I make offerings to the stands of trees near my home.
Neptune and Furrina
Coming into the driest part of the summer, the Romans were concerned about their water supplies. Held on July 23, the Neptunalia celebrates Neptune in his role as the God of Irrigation. Neptune (Neptunus) is the God of Fresh Water, and Salacia, the Goddess of Salt Walter, is regarded to be His Wife. (Neptunus Oceanus is Neptune of the Oceans.) On July 25, the Furrinalia was held for the Goddess Furrina, who watched over wells and other underground water sources. Modern Roman polytheists hold ceremonies to thank both Gods for water.
