Strange to say, however, no mention is as yet made by any of these works of Krishna's favourite Radha; it is only in another Purana - though scarcely deserving that designation - that she makes her appearance, viz.
The Vishnu Purana says, "The house-holder is to remain at eventide in his courtyard as long as it takes to milk a cow, or longer if he pleases, to await the arrival of a guest."
