Lughnasadh or as it can be known to Heathens Loaf-fest, Freyfaxi or Hlafmaest is a time of bounty, summer bearing crops are ready to harvest, the first loaves since grain stores ran empty are baked and ale and mead is brewed.
During this time it is only right that we share our bounty with the Aesir and the Wights as thanks for a good season, free of storms, vermin or disease to ruin the crops. It is also a forward payment on the next harvest too.
For modern heathens there are many interpretations of how to celebrate this time, however grain, bread, and ale are all good suggestions for things to offer at Loaf-fest, although if you are looking for more to offer consider using some of your harvest from your garden (or for those without a garden an offering of something that is in season where you are currently). Some of the more commonly praised gods and goddesses at this time are Thor, Freyr, and Sif.
It is also thought that this is a good time to make a corn dolly to sacrifice to the fire as part of your celebrations, the dolly is though to aid in warding of storms and vermin.
Some heathen scholars also argue that this is a good time of the year to bless wells and waterways, to keep the waters clean and pure, as well as warn of floods. They suggest giving the corn dolly to the waterway instead of the fire, however, there is nothing stopping you from making two and offering one to each. Just remember that anything you are offering to the waterway needs to be completely natural and biodegradable, you don’t want to pollute your local creek or river (or add to the pollution).
