The scribes of ancient Egypt were quite fond of word-games; this was a natural development for the land which Jean Capart chose to dub the “pays du symbolisme.”7 J. J. Clère has shown that the Egyptians com­posed not only crosswords, but acrostics as well.8 Etienne Drioton, the renowned Belgian Egyptologist and Catholic priest, in his “La Cryptographie Egyptienne,” gives several examples of Egyptian cryptograms (symbols — ornamental and otherwise — which convey dual meanings). These may consist of one or more symbols com­posing but a single word, or of entire sentences which have dual meanings. The latter most often display their dual meanings through homophones,9 to which we have had recourse in our Hor Sensen Papyrus investigations.\"§REF§THE USE OF MNEMONIC DEVICES IN ORAL TRADITIONS, AS EXEMPLIFIED BY THE BOOK OF ABRAHAM AND THE HOR SENSEN PAPYRUS By John A.

That is, on a shell signal all the men must gather in the men’s house, so that their wives are alone at home. Anyone can go to them at night without being punished, since, indeed, his wife too is abandoned.' §REF§Bollig, Laurentius 1927. “Inhabitants Of The Truk Islands: Religion, Life And A Short Grammar Of A Micronesian People”, 106§REF§ 'Closely bound up with the war history of the Truk people is the mateu; the word means ray spine or spear with ray spines. The mateu is the symbol of war. One who was experienced in military affairs received the name wasen mateu, bearer of the mateu. On the Truk Islands there were two large war parties, which usually stayed together except for minor internal quarrels. These war parties were called mateulap, large spear, and mateutun, small spear. The mateulap included the kin group of the Sapulupi with all the related kin groups. Mateutun included the kin group of the Soufar with the affiliated kin groups. Distributed by islands, Polvas /Poloas/, Wöla, Uman, and Paituk /Faituk/ were [Page 122] adherents of the mateulap; Pefan /Fefan/ with its little secondary islands, mateutun. These two mateu were continually contesting as to which of them was the more important. Numerically mateulap was considerably superior to the mateutun. The division into the two parts is connected with the kin-group system and the ida[unknown] institution, since even today they say ida[unknown]en mateulap, ida[unknown]en mateutun. I am not venturing to decide whether the institution is to be ascribed to the original inhabitants or to immigrants.' §REF§Bollig, Laurentius 1927. “Inhabitants Of The Truk Islands: Religion, Life And A Short Grammar Of A Micronesian People”, 121§REF§ Goodenough mentions 'mnemonic exercises', but does not mention any techniques or devices used in the process: 'The first ethnographer to work in Truk, J. Kubary, equated Achaw (Kachaw) with Kosrae (Kubary 1880:295). With one notable exception (Finsch 1893:450), subsequent scholars, myself included (Goodenough and Sugita 1980:19), have accepted this equation and sought to understand events in the oral tradition and to interpret the archeological record accordingly (Bollig 1927; Krämer 1932; Hambruch 1932-36; Fischer, Riesenberg, and Whiting 1977; Lessa 1980). Indeed, in the translations of native texts, they regularly render Kachaw as Kosrae or Kusaie. In his accounts of Carolinian navigators’ lore, Riesenberg (1972) does the same thing when the name Kachaw (Achaw, Araw) appears in the mnenomic exercises he recorded (see also Damm and Sarfert 1935:102-103). The effect for the reader is to make it appear as a matter of fact that Kosrae is the place designated. But the texts say nothing of Kosrae; they speak of Kachaw.' §REF§Goodenough, Ward Hunt 1986. “Sky World And This World: The Place Of Kachaw In Micronesian Cosmology”, 553§REF§"
