So the question arises, then, of what to offer them? Different types of deities seem to respond best to different kinds of offerings. For example, you wouldn't offer flowers to a war god, would you? When making an offering, it's important to think about what the god represents. The Roman Cato described an offering for agricultural prosperity: Make offerings to keep your oxen in good health. Make the following sacrifices to Mars... three pounds of wheat, four-and-a-half of lard, four-and-a-half of meat and three pints of wine. While it's probably not necessary to go that far and offer up enough food to feed a small army to your god, the passage does illustrate the fact that our ancestors thought enough of their gods to take their offerings very seriously.
In general, bread, milk and wine are nearly always appropriate for any deity. Here are some ideas for specific offerings you can make to deities, based upon the types of gods they are:
