Why Do the Romans Celebrate Vulcanalia?

The Romans celebrated Vulcan during the harvest season so they would pray that the grain stock and field would not  be destroyed by fires in the coming years (Pizzorusso). In the year 64 A.D. Rome had a devastating fire that left two-thirds of Rome in ruins (Backround). then in year 79 A.D. on August 24 the eruption of Vesuvius happened (Wallace). the eruption lasted for more than twenty-four hours, many corpses are still being found today from the lava flow (Wallace). It is because of these event that Vulcanalia was made. It is celebrated before the anniversary of the eruption of Vesuvius so that it would not happen again. As i mentioned before the people would make bonfires, sacrifice small animals, and eat and drink.
