Mr. Patron stroked his cheek and chin; examined the azure idol through his learned spectacles, and contradicted Frank in a clear, calm voice. "As usual, my dear Darrel, you speak without thinking," said he, "the image is not Egyptian at all." "It is the representation of a mummy," protested Frank, "and I always understood that the Egyptians were the only people who salted and dried their dead." "Then you understood wrongly," contradicted Patron. "The ancient Peruvians also embalmed their dead. This is the image of a Peruvian mummy." "How do you know?" asked Darrel, rather amazed at this remark. "Don't you see the representation of the sun on its breast?" snapped the other. "The ancient Peruvians were sun-worshippers. Judging from the solar symbol, I should say that this mummy comes from the tomb of some Inca. It is--what we call--a tomb image." "What is that?" questioned the visitor. Patron cleared his throat, adjusted his spectacles, and prepared for a long historical lecture. "In common with certain Asiatic nations," said he, "the ancient Peruvians practised the barbarous custom of immolating victims at the obsequies of great men. Sometimes--according to Prescott--a thousand attendants and favourite concubines would be slaughtered, so that they might accompany the dead Inca to his bright mansion in the sun. On occasions, however, the actual slaughter was dispensed with, and images of clay in the form of mummies, such as we see here," said the _savant_, pointing to the blue figure, "were substituted for human beings. For every counsellor, or slave, or wife, or attendant, a clay image was placed in the sepulchre of the dead; so that, in such instance, there would be many hundreds of these fictitious mummies arranged round the corpse. The figure we have here is an example of a tomb image. I hope I make myself clear?" "Perfectly," rejoined Darrel, slipping the image into his pocket. "But your lecture does not help me in the least." "In what way? Where did you get the mummy?" questioned Patron disconnectedly. "Out of a murdered woman's pocket." "Bless me! how strange! Why was she murdered? And how did she become possessed of so unique a curiosity as a Peruvian tomb-image? "Patron, my friend, those are two questions to which I am trying to obtain an answer." "If I can help you, Darrel----" "Thank you; Patron; but I fear you can help me no further. Good-day." "Good-day, good-day," replied the Egyptologist hastily; for his mind was already reverting to his own particular work, and he was becoming oblivious to the story told by his visitor. "Good-day;" after which he soared into cloudland.
