We must be able to answer the latter question before we may venture to classify the folklore of the Haggada.
It must, of course, be borne in mind that Halacha and Haggada are not separate works; they are two fibres of the same thread.
Halacha was the rule of religious praxis, a sort of Directorium Judaicum: Haggada was the result of free religious reflection.
The Haggada conveys its poetic message in the garb of allegory song, and chiefly epigrammatic saying.
That is a glimpse of the world of the Haggada—a wonderful, fantastic world, a kaleidoscopic panorama of enchanting views.
