 The "Acta Arvalia" preserve the names of four "functional goddesses" that are otherwise unknown.They were to be invoked for a "piaculum", a propitiation conducted in advance of destroying a tree.Their names, having the appearance of Latin gerundives, are Adolenda (in reference to burning the tree), Commolenda (reducing it to chips), Deferunda and Coinquenda (felling the tree).
