In this research I will trace the shape of the guardian lion statues in Egypt during the Graeco-Roman period, apart from the shape of the sphinx. At that time three different shapes of statues appeared:
The first shape: The lion appeared recumbent looking forward with his forelegs stretched and parallel to each other. This shape is considered the oldest shape of the guardian lions in ancient Egypt. The earliest lion statue of this shape dates back to the 4th or the 5th dynasty and was found in the city of Hierakleopolis in El-Fayum. This shape can be noticed in two guardian lion statues found in front of the temple of Madinet Madi, and the temple of Sobek at Tebtunis (Umm el-Baragat), El-Fayoum.
The second shape: The recumbent lion appears in a relaxing position with its head turns to the side, the forelegs and the hind legs crossed over each other. The oldest example of this shape dates back to the reign of Thutmosis III (18th dynasty). It seems that this shape was adapted from the Mesopotamian civilization. This shape appeared in front of the temple of Medinet Madi at El-Fayoum. Later, this relaxed position of the recumbent lion reflected on the sphinxes.
The third shape: A male lion is represented standing playing with a ball. This shape appeared in front of the door of the palace of Cleopatra that was found under the Alexandrian sea. This shape was very common in decorating the villas in ancient Italy.
