One of the means by which this sacred tradition was preserved was through the medium of rhythm and verse. Thus, as Sir Henry Maine explains, "The law book of Manu is in verse, and verse is one of the expedients for lessening the burden which the memory has to bear when writing is unknown or very little used. But there is another expedient which serves the same object. This is Aphorism or Proverb. Even now in our own country much of popular wisdom is preserved either in old rhymes or in old proverbs, and it is well ascertained that during the middle ages much of law, and not a little of medicine, was preserved among professions, not necessarily clerkly, by these two agencies."[124] In Greece the same word, νόμος, was used for custom and law as for song. The ῥήτρα (declared law) of Sparta and Taras was in verse; the laws of Charondas were sung as σκόλια at Athens,[125] and Strabo refers to the Mazacenes of Cappadocia as using the laws of Charondas and appointing some person to be their law-singer (νομωδός), who is among them the declarer of the laws.[126] Sir Francis Palgrave, noticing the same characteristic of Teutonic law, says:-- "It cannot be ascertained that any of the Teutonic nations reduced their customs into writing, until the influence of increasing civilisation rendered it expedient to depart from their primeval usages; but an aid to the recollection was often afforded as amongst the Britons, by poetry or by the condensation of the maxim or principle in proverbial or antithetical sentences like the Cymric triads. The marked alliteration of the Anglo-Saxon laws is to be referred to the same cause, and in the Frisic laws several passages are evidently written in verse. From hence, also, may originate those quaint and pithy rhymes in which the doctrines of the law of the old time are not unfrequently recorded."[127] Again, the editors of the Brehon Law Tracts point out that early laws are handed down "in a rhythmical form; always in language condensed and antiquated they assume the character of abrupt and sententious proverbs. Collections of such sayings are found scattered throughout the Brehon Law Tracts."[128] The sagas contain many verses which partake of the character of legal formulæ, and in Beowulf there seems to be a definite example. It occurs in the passage describing Beowulf engaged in his fatal combat with the fiery dragon, when his "companions," stricken with terror, deserted him, on which Wiglaf pronounced the following malediction:--
