The expression 'totemic age' involves a widened application of the term 'totem.' This word is taken from the language of the Ojibways or, as the English call them, the Chippewa Indians. To these Indians of the Algonquin race, the 'totem' signified first of all a group. Persons belong to the same totem if they are fellow-members in a group which forms part of a tribe or of a clan. The term 'clan,' suggested by the clan divisions of the Scottish Highlanders, is the one usually employed by English ethnologists in referring to the smaller divisions of a tribe. The tribe consists of a number of clans, and each clan may include several totems. As a rule, the totem groups bear animal names. In North America, for example, there was an eagle totem, a wolf totem, a deer totem, etc. In this case the animal names regularly refer to particular clans within a tribe; in other places, as, for example, in Australia, they designate separate groups within a clan. Moreover, the totem animal is also usually regarded as the ancestral animal of the group in question. 'Totem,' on the one hand, is a group name, and, on the other, a name indicative of ancestry. In the latter connection it has also a mythological significance. These various ideas, however, interplay in numerous ways. Some of the meanings may recede, so that totems have frequently become a mere nomenclature of tribal divisions, while at other times the idea of ancestry, or, perhaps also, the cult significance, predominates. The idea gained ground until, directly or indirectly, it finally permeated all phases of culture. It is in this sense that the entire period pervaded by this culture may be called the 'totemic age.'
