The tomb was discovered by municipality construction workers digging a trench to accommodate a sewage drain in the village of Kom Shaku, a district of Tama township.
A decision to suspend the sanitation project enabled archaeologists to explore the remains of the temple.
As a result, they found stones bearing inscriptions that read "Ptolemy IV," who ruled Egypt from 221 to 204BC.
Other carvings depicted the Egyptian god Hapi, the god of the annual flooding of the Nile, carrying offerings and surrounded by birds and other animals.
Archaeologists have at this point discovered a north-south wall, an east-west wall and the south western corner of the original structure.
Ptolemy IV is believed to have been the ruler under whom the beginning of the decline of the Ptolemaic dynasty began.
