Rabba, the son of Nachmani (270-330), Abayi (280-338), and Rava (299-352) gave the finishing touches to the method of the Talmud.

Rabba was a man of the people; he was a clear thinker, and loved to attract all comers by an apt anecdote.

Rava had a superior sense of his own dignity, and rather neglected the needs of the ordinary man of his day.
Abayi was more of the type of the average Rabbi, acute, genial, self-denying.

Under the impulse of men of the most various gifts of mind and heart, the Talmud was gradually constructed, but two names are prominently associated with its actual compilation.

These were Ashi (352-427) and Rabina (died 499).
