The phrase of pulling the ear is admonitory, that organ being regarded by the ancients as the seat of memory. It was customary also, and for the same reason, to take an oath by laying hold of the ear. It is impossible on this occasion to forget the passage in Isaiah xxii. 13, afterwards used by Saint Paul, on the beautiful parable in Luke xii. Plutarch also, in his banquet of the wise men, has remarked that the Egyptians exhibited a skeleton at their feasts to remind the parties of the brevity of human life; the same custom, as adopted by the Romans, is exemplified in Petronius's description of the feast of Trimalchio, where a jointed puppet, as a skeleton, is brought in by a boy, and this practice is also noticed by Silius Italicus: ... Ægyptia tellus Claudit odorato post funus stantia Saxo Corpora, et a mensis exsanguem haud separat umbram.[5] Some have imagined that these skeletons were intended to represent the larvæ and lemures, the good and evil shadows of the dead, that occasionally made their appearance on earth. The larvæ, or lares, were of a beneficent nature, friendly to man; in other words, the good demon of Socrates. The lemures, spirits of mischief and wickedness. The larva in Petronius was designed to admonish only, not to terrify; and this is proved from Seneca: "Nemo tam puer est ut Cerberum timeat et tenebras, et larvarum habitum nudis ossibus cohærentium."[6] There is, however, some confusion even among the ancients themselves, as to the respective qualities of the larvæ and lemures. Apuleius, in his noble and interesting defence against those who accused him of practising magic, tells them, "Tertium mendacium vestrum fuit, macilentam vel omnino evisceratam formam diri cadaveris fabricatam prorsus horribilem et larvalem;" and afterwards, when producing the image of his peculiar Deity, which he usually carried about him, he exclaims, "En vobis quem scelestus ille sceletum nominabat! Hiccine est sceletus? Hæccine est larva? Hoccine est quod appellitabatis Dæmonium."[7] It is among Christian writers and artists that the personification of Death as a skeleton is intended to convey terrific ideas, conformably to the system that Death is the punishment for original sin.
