In ancient Roman religion, the Robigalia was a festival held April 25. Its main ritual was a dog sacrifice to protect grain fields from disease. Games (ludi) in the form of "major and minor" races were held. The Robigalia was one of several agricultural festivals in April to celebrate and vitalize the growing season, but the darker sacrificial elements of these occasions are also fraught with anxiety about crop failure and the dependence on divine favor to avert it.
The late Republican scholar Varro says that the Robigalia was named for the god Robigus, who as the numen or personification of agricultural disease could also prevent it. He was thus a potentially malignant deity to be propitiated, as Aulus Gellius notes. But the gender of this deity is elusive. The agricultural writer Columella gives the name in the feminine as Robigo, like the word used for the disease itself, and says that the sacrificial offering was the blood and entrails of an unweaned puppy (catulus). Most animal sacrifice in the public religion of ancient Rome resulted in a communal meal and thus involved domestic animals whose flesh was a normal part of the Roman diet; the dog occurs as a victim most often in magic and private rites for Hecate and other chthonic deities, but was offered publicly at the Lupercalia and two other sacrifices pertaining to grain crops.
Purpose and origin 
|Practices and beliefs|
Robigo is a form of wheat rust, and has a reddish or reddish-brown color. Both Robigus and robigo are also found as Rubig-, which following the etymology-by-association of antiquity was thought to be connected to the color red (ruber) as a form of homeopathic or sympathetic magic. The color is thematic: the disease was red, the requisite puppies (or sometimes bitches) had a red coat, the red of blood recalls the distinctively Roman incarnation of Mars as both a god of agriculture and bloodshed. William Warde Fowler, whose work on Roman festivals remains a standard reference, entertained the idea that Robigus is an "indigitation" of Mars, that is, a name to be used in a prayer formulary to fix the local action of the invoked god. The priest who presided was the flamen Quirinalis, the high priest of Quirinus, the Sabine god of war who become identified with Mars; the ludi were held for both Mars and Robigo. The flamen recited a prayer that Ovid quotes at length in the Fasti, his six-book calendar poem on Roman holidays which provides the most extended, though problematic, description of the day.
Like many other aspects of Roman law and religion, the institution of the Robigalia was attributed to the Sabine Numa Pompilius, in the eleventh year of his reign as the second king of Rome. The combined presence of Numa and the flamen Quirinalis may suggest a Sabine origin.
Other observances 
Chariot races (ludi cursoribus) were held in honor of Mars and Robigo on this day. The races had two classes, "major and minor," which may represent junior and senior divisions. In chariot racing, younger drivers seem to have gained experience with a two-horse chariot (biga) before graduating to a four-horse team (quadriga).
Calendar context 
The Fasti Praenestini also record that on the same day the festival celebrated a particular class of sex workers: "pimped-out boys," following the previous day's recognition of meretrices, female prostitutes regarded as professionals of some standing.
Other April festivals related to farming were the Cerealia, or festival of Ceres, lasting for several days in mid-month; the Fordicidia on April 15, when a pregnant cow was sacrificed; the Parilia on April 21 to ensure healthy flocks; and the Vinalia, a wine festival on April 23. Varro considered these and the Robigalia, along with the Great Mother's Megalensia late in the month, the "original" Roman holidays in April.
The Robigalia has been connected to the Christian feast of Rogation, which was concerned with purifying and blessing the parish and fields and which took the place of the Robigalia on April 25 of the Christian calendar. The Church Father Tertullian mocks the goddess Robigo as "made up," a fiction.

- This dual function of Mars, contradictory perhaps to the 21st-century mind, may not have seemed so to the Romans: "In early Rome agriculture and military activity were closely bound up, in the sense that the Roman farmer was also a soldier (and a voter as well)": Beard, Religions of Rome, pp. 47–48 online and 53.

- Precise naming, in connection with concealing a deity's true name to monopolize his or her power, was a crucial part of prayer in antiquity, as evidenced not only in the traditional religions of Greece and Rome and syncretistic Hellenistic religion and mystery cult, but also in Judaism, ancient Egyptian religion, and later Christianity.

Augustine of Hippo derided the proliferation of divinities as a turba minutorum deorum, "a mob of mini-gods" (De civitate Dei 4.9, dea Robigo among them at 4.21); see W.R. Johnson, "The Return of Tutunus," Arethusa (1992) 173–179. See also indigitamenta.

In his notes to Aeneid 1.292 and 6.859, Servius says that "when Mars rages uncontrolled (saevit), he is called Gradivus; when he is calm (tranquillus), he is called Quirinus." Therefore, since Quirinus is the "Mars" who presides over peace, his temple is within the city; the temple for the "Mars of war" is located outside the city limit. The name was also connected to Quirites, Roman civilians, and the civil comitia curiata, in contrast to military personnel and the comitia centuriata. Quirinus was assimilated with the deified Romulus, possibly as late as the Augustan period.
