Pii fratres

Head (Historia nummorum): "... during a fearful eruption of Aetna in the fifth century, when a stream of lava was descending upon Catana, and when every man was eagerly bent upon saving his treasures, the brothers Amphinomos and Anapias bore off on their shoulders their aged parents, but the lava overtook them, heavily laden as they were, and their doom seemed inevitable, when the fiery stream miraculously parted and let them pass scatheless. Ever after the Catanaean brethren were held up as types of filial piety, and received divine honours
