halomancy

Divination by salt. What particular method of divination this word originally was applied to is unknown, however, in Frazer's Golden Bough (x. 244) we find that in the Isle of Man on Halloween

	the housewife fills a thimble full of salt for each
	member of the family and each guest; the contents of
	the thimblefuls are emptied out in as many neat piles
	on a plate, and left there over night. Next morning
	the piles are examined, and if any of them has fallen
	down, he or she whom it represents will die within
	the year.
This, of course, is in the days when salt did not come with an anti-caking agent added.

Also, this word could refer to the unlucky omen designated by the spilling of salt. This, nowadays, is expiated by throwing a little of the spilt salt over the shoulder. This superstition dates back to Roman times.

Also in the erroneous form alomancy.

Etymology

Clearly a modern word, as the first element is the New Latin combining form halo-. This is normally used to form scientific words to do with either "salt" or "the sea", and in chemistry siginifies the presence of "halogen". It is not to be found in any word before the early 19th century (the earliest being halogen and haloid dating from the 1840s). The New Latin halo- comes from the ancient Greek combining form of hals salt. The word also appears in French as halomancie.

Potter quoting Clemens Alexandrinus Stromateis.
By some [hieromancy] was feigned to have been first occasioned, or very much improved, by the death of the Delphian Sibyl, whose body being reduced to earth, imparted first to herbs, and by their means to beasts, which fed on them, a power of divining: as also those other parts of her, which mixed with the air, are said to have occasioned the divination by ominous words.

Etymology

From New Latin heiromantia, from the ancient Greek hieromantia, from hieros holy, sacred.

hydromancy

Divination by means of water.

Etymology

Originally in Middle English this word was spelled ydromancy (from Middle French ydromancye). This form is a result of the h being etymologically restored during the Renaissance under the influence of better knowledge of Latin and Greek, and under the influence of the New Latin hydromantia.
Ultimately it comes from Late Latin hydromantia, from the ancient Greek *hydromanteia, from hydro-, combining form of hydor water. In ancient Greek the word hydromantis diviner by water, was recorded.

Variant Forms

Middle English: hidromancy, idromance, idromancie, ydromance, ydromaunce.
Surviving in modern English: hydromancie, hydromantie, hydromanty, ydromancy.
New Latin: hydomantia.

Edward Smedley in Ibid. 317: hydromancy. Divination by water, is said by Natalis Comes (ii. 6), to have been the invention of Nereus, and according to Delrio, a most respectable authority in these matters, it is a method of divination, than which nulla f§cundior imposturis. Jamblichus, he says, mentions one kind of hydromancy to which the Emperor Andronicus Comnenus had recourse; not in person, for regard for his character (a character richly demanding such caution!) forbade this humiliation; ipse quidem iis nocturnis sacris interesse noluit, metu famœ ut arbitror, sed illud Hagiochristophoritœ Stephano mandat. This worthy applied to Sethos, a diviner, who from his youth upward had been addicted to magic, and on that account had been deprived of sight by the Emperor Manuel. The question proposed by hydromancy was, who was to be the successor of Andronicus, a doubt which grievously perplexed the superstitious tyrant, and left him in hesitation as to the fittest victim whom his suspicious vengeance might first sacrifice. The evil spirit when summoned, showed upon the water the letters S I, and upon being asked at what time the person so designated should succeed, he replied, before the feast of the exaltation of the Cross. His prediction was verified, for, within the time named, Isaac Angelus had thrown Andronicus to be torn to pieces by the infuriated populace of Constantinople. It should be remembered here that the devil spells, as he repeats the Lord's Prayer, not in a natural order, but backwards. S I when inverted, would fairly enough represent Isaac according to all laws of magic. The same story is related with great spirit by Nicetas ('Andron. Comn.' II. 9). The arts with which the tempter cheats the ear of his votary are vividly displayed, and there is one very picturesque touch, when the fiend is asked respecting time, which we are surprised should have escaped Delrio, who evidently borrows from this source, though he refers to Jamblichus. The annalist has already remarked, that he neither knows, nor indeed wishes to know, the method of practising hydromancy, but Delrio, on the contrary, describes several kinds. In one, a ring was suspended by a thread in a vessel of water, and this being shaken, a judgement was formed according to the strokes of the ring against the side of the vessel. In a second, three pebbles were thrown into standing water, and observations were drawn from the circles they formed. A third depended upon the agitations of the sea; whence the learned Jesuit deduces a custom prevalent among the Oriental Christians of annually baptising that element... A fourth divination was taken from the colour of water, and certain figures appearing in it, which Varro (according to Apuleus in his 'Apologia') says afforded numerous prognostics of the event of the Mithridatic War. But this branch was of sufficient importance to deserve a separate name, and we read accordingly of &pgr;&agr;&lgr;&ogr;&mgr;&agr;&ngr;&tgr;&egr;&igr;&agr; [see note], divination by fountains, these being the waters most frequently consulted.

Elihu Rich in
Ibid. 319: Hydromancy is, in principle, the same thing as divination by the crystal or mirror, and in ancient times a natural basin of rock kept constantly full by a running stream, was a favourite medium. The double meaning of the word reflection ought here to be considered; and how, gazing down into clear water, the mind is disposed to self-retirement and to contemplation, deeply tinctured with melancholy.

1903 Daniels & Stevans Encyc. Occult Sci. (1971) III 1662: hydromancy - Divination by the images or other appearances caused to appear in water, as of a fountain. It was performed thus: Round vessels were filled with clear water, about which were placed lighted torches; they then invoked the demon, in a low, murmuring voice, and proposed the question to be solved. A chaste boy or a pregnant woman was appointed to observe with the greatest care and exactness all the alterations in the glasses, at the same time desiring, beseeching and also commanding an answer, which at length the demon used to return by images in the glasses, which by reflection from the water represented what should come to pass. There can be no doubt that Joseph had learnt this sort of divination from the Egyptians. It was his divining cup or bowl which was found in Benjamin's sack. "Is not this it (the bowl) in which my lord drinketh, and whereby indeed he divineth?" (Gen. XLIV 5.). Again when brought back, Joseph himself said to his brethren: "What deed is this that ye have done? wot ye not that such a man as I can certainly divine?" (Gen. XLIV 15). He evidently took it for granted that his brethren would believe he could ascertain by magic who had stolen the money and the cup.

Practitioners would dangle a ring from a thread into still water, or would study the circles formed by three little stones thrown into still water, or would throw a drop of oil into water and see future events in it as in a mirror.
Ibid. 308: We still have to consider, as a variant of hydromancy, the celebrated process of divination by coffee-grounds. This was already in existence in the eighteenth century, but naturally cannot have been anterior to the introduction of this beverage into Europe. The treatise regarding the process published by Tomaso Tomponelli gave reason for thinking that it was first conceived in Italy. Our modern pythonesses all employ it; they pour some coffee-dregs on a white unglazed plate, allow them to settle, and then carefully drain off the water. The particles of coffee- grounds left on the plate form a multitude of patterns which can be interpreted in various ways...

1939 J. Trachtenberg Jewish Magic 219: Other methods, equally well known in Christian Europe, were to interpret the shapes assumed by drops of oil or melted wax floating on the surface of a basin of water, and to suspend a ring of pure gold over a goblet of water and divine by the sounds it makes as it strikes against the sides of the goblet (departments of Hydromancy).

1973 Gibson Complete Illust. Bk Div. & Prophecy (1989) 318: HYDROMANCY: This relates to forms of divination with water, which naturally figures in other types of predictions involving various objects, which are therefore listed under separate heads. In some cases, however, water plays such an important part that they must be regarded as hydromancy despite the presence of those other factors. One method is to study the depths of a placid pool, noting any images or symbols that appear therein, interpreting them as seems most fit. This is similar to using a magic mirror (as with catoptromancy) or gazing into a crystal ball (as with chrystallomancy) but on a large scale. However, if results are slow, another type of hydromancy may be used; that of dropping three stones into the pool and noting any figures or other effects caused by the ripples. For best results, the first stone should be round, the second triangular, the third square. Diviners who used this method generally referred to special lists that told the proper interpretations to be given to various types of ripples. Another time-honored method was to invoke any evil spirit that dwelled in the neighborhood of a pool or stream. This demanded knowledge of cabalistic ceremonies, with all the danger accompanying such work, putting it into the realm of demonomancy. However, it still depended on hydromancy to a marked degree, since the demon's mode of answering questions was by inscribing words on the surface of the water. Often, these were visible to the seer alone, and they had to be read quickly while they lasted, as they were invariably written backward, to prove that they were the devil's work. Methods of hydromancy that were both simpler and safer included casting offerings, such as bread, into a pool. If they remained there, it was a good omen; if they drifted ashore before they sank, it boded ill. This may account for the still popular custom of throwing coins into a fountain for good luck, as they are sure to sink and stay there. Where names of persons are involved, the old way of picking one through hydromancy was to write each name on a separate stone and toss them all in a pool. Later, the stones were fished out and if all the names were washed off, or nearly so, with the exception of one, that name represented the person to whom the question pertained. A modern combination of these methods, which is simpler, easier and more convenient, is the Floating Slip.

Sometimes they threw Stones into the Water, and observed the Turns they made in sinking.

hyomancy

According to Shipley, divination by the "tongue bone", or "as the tongue wags".
What exactly Shipley means I am not sure. The two definitions seem to be referring to quite differnt things. Divination by the hyoid bone, or as he calls it, the tongue bone, could refer to the practice of cephaleonomancy. Divination as the tongue wags could refer to logomancy or labiomancy. It is obvious that in his treatment of the -mancy words Shipley is flippant because of the contempt in which he holds such practices. Thus his definitions are not very reliable.

Etymology

Derived from the New Latin combining form hyo-, referring to the hyoid bone, a bone running from the root of the tongue to the larynx, from New Latin hyoides, from the ancient Greek (osteon hyoeides) the hyoid bone (so named since it is shaped like the Greek letter upsilon (&ugr;)]

1955 Shipley Dict. Early Eng. (1963) 16: hyomancy, the tongue bone; as the tongue wags. 1986 P. Hellweg Insomniac's Dict. x. 75: Hyomancy - the tongue.
