The title of the article, which includes a concept of common day life, should not mislead the reader, since the work is primarily theoretical. The author, in fact, turns out to be a pioneer in two areas at once, which for the 1920s were just incipient, but nowadays are flourishing under the name ritual studies and food studies, respectively. With that article K. carried out both theoretical work on the analysis of ritual in its self, and the application of that theory to the study of private manifestations of ritual, that is, sacrifices in Ancient Greece. The theoretical premises of the work are following: linguistics, archeology, philology, and ethnography are only auxiliary disciplines in the study of religion, while the priority belongs to sociology and to the methods developed in it. Classical gods were functions of cult and myth, and their role was formal and constructive, in other words, secondary in the same sense in which the explanation of ritual was secondary, given its stable uniformity. Magical action was initially an aim in itself, and only gradually and in part it was associated with a certain deity – within the framework of the opposition of magic as an earlier stage without any cults of deities, and religion, it was the sacrifice that signified the appearance of the latter one. The author understood sacrifice as a kind of legal transaction that had the character of exchange.
It was feeding, according to K., that turned out to be the main component of sacrifice, and it was from the slaughter of a meat animal preceding a ritual meal that the author deduced the ritual of sacrifice. In the summary of the article K. made conclusions that remain valid up nowadays: obtaining and preparing food created a system of social relations and practices; rethinking those practices created a ritual life and mythology associated with food; a banquet festival was the basis of sacrifice; the ritual of the latter as a cult action reproduced techniques of slaughter; other functions of sacrifice were built by analogy with the social and legal agreement.
