AḤA B. JOSEPH:
By: S. Mendelsohn
A Babylonian amora who flourished in the fourth and fifth centuries. His life was an unusually long one; for in his youth he attended Ḥisda's lectures (306), and in his old age discussed halakic matters with Ashi II. (died 427). It is stated that he was afflicted with asthma, for which Mar Ukba prescribed three ounces of asafetida to be taken in the course of three days. During another severe attack, he was treated medically by Kahana (Shab. 110b, 140a; B. M. 87a, 109b; Men. 35b; 'Er. 29b; Yeb. 31b; B. M. 109b; Ḥul. 105a).
