He was appointed by Osorkon II to the office of chief priest of Amun at Tanis to strengthen this king's authority in Lower Egypt.

[1] When Hornakht died at this young age, Osorkon II made provisions to ensure that his son would be buried in this king's own tomb at Tanis.

Therefore, when Egyptologist Pierre Montet discovered the burial of Hornakht, they found a series of gold amulets which covered parts of the prince's mummy.

They are small in size but enjoy a high quality finish; some are made of gold partitioned lapis lazuli and other semi-precious stones which represent various mythical symbols intended to safeguard the sanctity of Hornakht's mummified body.

On the remains some peculiarities were noted, such as an unusually large and developed skull for his age, the presence of a pair of cervical ribs, and an abnormal lumbar vertebra; however, Derry excluded that these anomalies may have led to Hornakht's premature death.
