The Guard Stones Of Ancient Sri Lanka

The ruins of Sri Lanka’s ancient kingdoms are a testament to the architectural skill of our ancestors. They have several unique architectural features including intricately carved stairs, the moonstones that lie at the foot of the stairs, and the guard stones that are placed on either side of the stairs at the entrances to these historic and religious sites. Among these, the guard stones, known as muragal in Sinhalese, are particularly fascinating. These features of Sinhalese architecture have both practical and decorative purposes.

 Some academics believe that the concept of guard stones found its way to Sri Lanka from India

The purpose of a guard stone

 Over the years, many theories about the true purpose of a guard stone have been put forward by historians and archaeologists. Some archaeologists, like Dr. Charles Godakumbura, former commissioner of the Department of Archaeology in Colombo, have stated that guard stones were designed to protect the balustrade (korawakgala) that runs along the side of the stairs at the entrance.

Others like Professor Chandra Wickramage, the head of the editorial team that authored the latest volume of the Mahawamsa, criticise this theory, suggesting that guard stones merely had a decorative purpose, as features of the entrance to ancient buildings of social and religious importance.

The earliest guard stones were plain and uncarved

Guard stones and gatekeepers

Because guard stones have only been found at the entrance to temples and royal palaces, there is a belief among many people that they were installed for protection from thieves and evil spirits.

Even though guard stones are considered a unique feature of Sinhalese architecture, some academics believe that they were originally influenced by Indian art and architecture. For instance, the paintings of ‘gatekeepers’ at the Ajanta cave temple bear similarities with the guard stones. Therefore, it is quite possible that this symbolic concept of guarding doorways may have found its way to Sri Lanka from India.

The evolution of guard stones

The very earliest guard stones, moonstones and balustrades, were created with pieces of valuable wood. Many of the early guard stones were uncarved, and archaeologists now use this detail to identify the age of some historic buildings.

Speaking to Roar Media, archaeologist Professor Nimal de Silva said that the earliest guard stones date back to about the 1st century A.D—the early period of the Anuradhapura Kingdom. Over time, the architects of the Anuradhapura kingdom used stone, instead of wood, for the construction of guard stones, moonstones and balustrades, as stone was a more enduring material.

The next stage in the evolution of the guard stones was the inclusion of carvings. It is, however, difficult to pinpoint the exact time period when these changes began to take place as research is still being conducted.

Four different motifs have been identified on guard stones: the punkalasa (or pot of flowers which symbolises prosperity)the dwarf or eunuch, the serpent with multiple heads and the naga raja or serpent king.

Where you can find these motifs

 The punkalasa is a symbol of prosperity

The guard stone with the image of the punkalasa can be seen at the Ras Vehera cave temple in Anuradhapura, the Welgam Vehera in Kanniya, the Magul Maha Vihara in Lahugala and even at the Kaludiya Pokuna at Mihintale. Professor Nimal de Silva noted that while guard stones are mostly found at the entrances of temples, monasteries and royal palaces, it is not unusual to find this architectural feature at entrance of sites such as the Kaludiya Pokuna bathing pond.

Another example of this motif is the northern doorway of the convention hall at the Abhayagiri Viharaya, which features a guard stone with images of a punkalasa and a kapruka (a mythical tree with magical powers). Archaeologists, however, consider the guard stone at Toluvila in Anuradhapura as the best example of a guard stone bearing the symbol of prosperity.

The images of the dwarves may have been carved onto guard stones to protect valuable relics housed inside stupas and viharas.

During the middle period (2nd century A.D. – 6th century A.D.) and the latter period (7th century A.D. – 11th century A.D.) of the Anuradhapura kingdom,  stone workers began to carve the image of a dwarf on the guard stones. This was due to the rural superstition that dwarves, known as vamana in Sinhalese, had magical powers and were the protectors of treasure.

This belief stems from the Meghaduta, a Sanskrit poem written by the poet Kalidasa, which speaks of two dwarves by the name of Sankha and Padma who were the guardians of the treasurethat belonged to Kuvera, the god of wealth and prosperity. The guard stone depicting the dwarf Sankha can be identified by a small carving of a conch shell, while the companion guard stone depicting the dwarf Padma would include the carving of a lotus bloom.

Professor de Silva noted that the purpose of carving such an image on guard stones may have been to protect valuable items and relics that were housed inside places of religious veneration. “The symbols of the conch and the lotus were not only associated with Sankha and Padma,” stated Professor de Silva. “The conch and lotus were the symbols of God Brahma as well, and he, along with the God Sakra, gave protection to Lord Buddha.”

The guard stones bearing the images of these dwarfs can be found at the Abhayagiri Temple, the Wijerama Vihara Geya in Anuradhapura and the Rajagiri cave temple of Mihintale.

 The serpents featured on the guard stones of the latter period of the Anuradhapura kingdom had several heads

Towards the latter stages of the Anuradhapura Kingdom, guard stones with the images of serpents or cobras were carved. These images featured serpents with five or seven heads. The most notable example of such a guardstone is the one at the Kuttam Pokuna in Anuradhapura.

The ancient Sinhalese people considered the serpent to be a deity with power over water, and this could be the reason why many of the guard stones bearing the images of serpents have been found at places situated near bodies of water.

There are many theories about the multiple heads of the serpents on these guard stones. Some archaeologists and historians believe that the carvings of the five-headed serpent may be symbolic of the five senses—sight, smell, sound, taste and touch—which, according to Buddhism, allow a person to feel desire.

Professor de Silva, however, believes that the number of heads in the serpent images were decorative and not symbolic.

The naga raja guard stones were carved with the image of the serpent king or naga raja

The guard stone with the image of the naga raja is the best known of all guard stones of Sri Lanka. As Professor de Silva noted, the naga raja guard stones were carved with the image of a serpent king, a protective deity who was revered by the ancients. The naga raja were also referred to as naga dwarapala in the Sanskrit language.

The naga raja guard stones depict a male figure with a five or seven-headed serpent hood holding a punkalasa in one hand, with a dwarf or two dwarves standing near the feet of the serpent king. The entrance of the Rathna Prasadaya of Anuradhapura has a beautifully preserved naga raja guard stone which is believed to have been carved during the days of King Mihindu.

While many theories surrounding the artistic components of the guard stones are suggestions and speculations, it is important to note that many historians and archaeologists believe that the naga raja guard stones are a combination of the ones that were carved before it. With research still ongoing, the debate around the guard stones are bound to provide new insights into the lives and times of the ancients.

Sasni Amarasekara:  “An Introduction to Concept and Evolution of the Guardstone and Its Architectural Visualization of the Contemporary Religious and Cultural Diversities,” Journal of the Arts & Humanities, 2017, vol 6/3.

This specific study deals with a unique piece of Buddhist architecture, the Guardstone found almost in every part of ancient kingdoms in Sri Lanka spanning from Anuradhapura to Kandy period significantly. The Guardstone is an excellent piece of structure placed on either side of the first step of the flight of stairs at the entrance of ancient religious buildings or palaces in Sri Lanka. The origin of this architectural masterpiece is still to determine. Nevertheless, it is widely accepted in an evolutionary point of view that the guardstone has passed through several developmental stages from a simple slab to a highly sophisticated artifact in its dimensions, complexity and artistry. The numerous inclusions as well as exclusions from time to time to this artifact still remain uncertain as to whether they were due to secular or ecclesiastical reasons or simply due to the creators own culture influenced imagination. This study will peruse all the possible evidence that are available architecturally and to develop a logical reasoning for any identifiable characteristic and to elucidate with reasonable legitimacy as to how and why such a character is present or absent in a particular guardstone. This study in no way has any intention of rejecting or amending any proposition available at present but will pursue its best to shed light only on the attributes of a guardstone and to concentrate on the diversities of this beautiful monastic artifact that deserves serious academic study and meticulous aesthetic evaluation.
