The Colossal Statue of Shapur I, a statue of Shapur I (AD 240–272), the second king of the Sassanid Empire, stands in the so-called Shapur cave, a huge limestone cave located about 6 km from the ancient city of Bishapur in the south of Iran. The statue is about 35 m from the cave entrance, on the fourth of five terraces, lying approximately 3.4 m below the level of the cave entrance. Its height of about 6.7 m and breadth across the shoulders of more than 2 m make it one of the most impressive sculptures from the Sassanian period.
The monumental sculpture is chiseled from a huge stalagmite grown in situ, but it no longer stands exactly in its original position. After its fall (probably caused by an earthquake), the sculpture was raised onto two concrete pillars, which are located near the original feet. The head and the body of the sculpture have remained quite well preserved while parts of its arms and almost all of both legs are missing.
The colossal statue is rich in detail. It is chiseled on every side with the same amount of extraordinary care and attention. The king wears a crenellated crown. A large piece of the front crenellation is missing, while the crenellations of both sides and the rear are well preserved. At the lower end of the crown, there is a wide diadem. The two bands of the diadem fall heavily down the back to the waist and widen from top to bottom. Around twenty horizontal, parallel furrows cross on these bands. The head of the sculpture has been carved out in all its particulars symmetrically. The hairstyle of the colossal statue shows a high degree of sculptural definition. The mass of hair on the left side of the sculpture has remained intact while the ends of strands of hair on the right side are broken off. Of the left arm of the sculpture, only half remains. The missing left hand of the sculpture must have once rested on the sword handle. The right arm is broken off just below the axilla. A small part of the right underarm is still attached. The right hand is strongly weathered and rests on the waist.
The clothing of the colossal statue consists of three pieces: an undervest, an upper garment and wide trousers. The upper garment of the sculpture fits tightly to the body and appears to be made of a sheer fabric. Through its skin-tight fit, the shoulders, the upper arms and the chest of the king have been emphasized. The sculpted ornaments on the upper garment are quite remarkable insofar as they resemble flames flickering downward. These are varyingly long, shaped in several different ways and irregularly arranged. At the waist, the upper garment is held together tightly by a belt while a second belt, which is hanging loosely around the hips, functions to fasten on the sword scabbard.
