Macrobius, Saturnalia 2.2.8:
“There was once among the ancients a type of sacrifice which they called a ‘for the road.’ The custom was that if anything was left over from a feast, it was burned in the fire. This is the source of one of Cato’s jokes. He said that a certain Albidius, who had consumed his own goods and had recently lost everything which was left in a fire had made a ‘for the road’ – what he wasn’t able to consume, he burned!”
Sacrificium apud veteres fuit quod vocabatur propter viam. In eo mos erat ut, si quid ex epulis superfuisset, igne consumeretur. Hinc Catonis iocus est. Namque Albidium quendam, qui bona sua comedisset et novissime domum quae ei reliqua erat incendio perdidisset, propter viam fecisse dicebat: quod comesse non potuerit, id combussisse.
