The worship of Osiris was a central aspect of Egyptian religion for millennia. The cult of Osiris developed over time and varied in its practices and beliefs depending on the time period and location within Egypt. However, there were certain elements of Osirian worship that were consistent throughout Egyptian history.

One of the most important aspects of Osirian worship was the performance of rituals that aimed to honor and appease the god. These rituals included offerings of food, drink, incense, and other items, as well as the recitation of prayers and hymns. In some cases, animals were sacrificed in Osiris's honor.

Osirian worship also involved the construction of temples and shrines dedicated to the god. These buildings were often located near tombs or other significant sites associated with Osiris's myth, such as the city of Abydos, where the god was believed to be buried.

In addition to public worship, Osiris was also venerated in private homes, where individuals could make offerings and prayers to the god. Amulets and other items associated with Osiris were also popular among the general population, as they were believed to offer protection and good fortune.

The Osirian cult also had a strong emphasis on the afterlife and the journey of the soul through the underworld. As the judge of the dead, Osiris played a crucial role in determining the fate of the deceased. Many funerary texts and spells were dedicated to Osiris, asking for his protection and guidance in the afterlife.

Overall, Osirian worship was a multifaceted and complex practice that played an important role in the lives of the ancient Egyptians. It reflected their beliefs about life, death, and the afterlife, as well as their desire to honor and connect with the divine.
