A friend of Anāthapiṇḍika. They had made mud-pies together and had gone to the same school. Later, Kāḷakaṇṇi fell on evil days and sought the protection of his friend, who appointed him to look after his business. Anāthapiṇḍika’s friends and acquaintances remonstrated against the employment of a man with so inauspicious a name, but Anāthapiṇḍika heeded them not. One day, when Anāthapiṇḍika was away, a gang of robbers tried to enter his house, but Kāḷakaṇṇī, with great presence of mind, asked the few remaining servants to beat drums all over the house, thereby giving the impression that the house was fully occupied. The robbers fled leaving their weapons, and Kāḷakaṇṇī was greatly praised. When Anāthapiṇḍika reported the matter to the Buddha, the Buddha related the Kāḷakaṇṇi Jātaka, containing a similar story of the past. J.i.364 f.
