Terminalia was the festival in honour of Terminus, god of boundaries. The festival included garlanding a local boundary stone and making offerings to the god at an altar; these might include crops, honeycombs, and wine. The blood of a sacrificed lamb or pig would be poured over the boundary marker itself.
