Then we have this further reason: it will be seen, when we come to consider the _objects_ of dancing as a mourning rite, that they involve beliefs which seem to be common to man during some stages in his cultural and religious development. It is difficult to suppose that what had been characteristic of man generally should not have been so in the case of the Israelites. We touch upon this point again later. But, finally, the strongest reason for believing that this custom was in vogue among the ancient Israelites is that it exists at the present day. Such things as mourning and burial customs are never innovations; modifications may arise, as we have just said; a custom may fall into disuse and be discontinued altogether; but when a rite is practised at the present day, it is not a new thing, but has a long history behind it. Regarding the particular example to be given presently it is known to go back at any rate to the beginning of the Christian era; but it is safe to say that it must be vastly older than that in reality; for of all customs none are so tenacious as those which have to do with mourning and burial, for they touch men at a very sensitive spot. If at _any_ time such a custom as we are thinking of is known to have existed, or to exist now, it may be taken for granted that, as a matter of fact, it goes back to very much earlier, indeed to prehistoric, times. That much may be safely gathered from what we know of the customs of savage man and the way in which so many of them are still existent in modified forms. So that since, at the least, something corresponding to the sacred dance as a mourning rite is still in vogue among some of the Jews, it is hardly too much to say that that _ipso facto_ proves its existence among their Hebrew ancestors in days gone by. One other consideration may be urged. It must be allowed that the number of words found in the Old Testament for dancing is significant. When we know that dancing on various religious occasions formed an important element, as shown in the preceding chapters, the presumption is strong that it occurred also during the very solemn period of mourning. It may, then, be contended that the cumulative effect of these arguments justifies the belief that the sacred dance as a mourning or burial rite was well known to, and practised by, the ancient Israelites, and that the silence of the Old Testament upon the subject is no reason to doubt this.
