In the year 1873 just one year after the death of Somdej Pra Puttajarn Toh, cholera outbreak had killed many people in the country. Somdej Toh has come to the dreams of many people that Pra Somdej amulet could cure that deadly cholera disease by drinking holy water by dipping them in water. Wat Saket appears in most 19th - century accounts of Bangkok not only because of its Golden Mount but also because it was a resting place for the dead during cholera epidemics. Too numerous for conventional cremation, the bodies were laid out at the temple for vultures to devour.
Anna Leonowens, the Englishwoman who was hired by King Rama IV to teach some of his majesty's wives and children, wrote: “None but the initiated will approach these grounds after sunset, so universal and profound is the horror the place inspires – a place the most frightful and offensive known to moral eyes.” Paupers and unidentified dead bodies were also brought to Wat Saket for more conventional cremation.
Besides there are many circumstances of the magic of Pra Somdej during those times that have made the needs to search for Pra Somdej amulets more. In 1882 some of Pra Somdej were stolen by way of dropping a rope with one end sticking with clay or soaking with glue into the Niche to catch the amulets up. This was done many times and many amulets were lost. The amulets obtained at these times were called Pra Somdej of Old Niche (book reference below - Somdej WRK green cover).
Therefore in 1957 the official opening of the Niche was done and Pra Somdej amulets were sold to public to raise fund for the purpose of renovation and improvement of the monastery. The amulets obtained at this time were called Pra Somdej of New Niche (book reference below - Somdej WRK green cover)
The texture of Pra Somdej of old niche is of fine texture without or with little sediments. In contrast Pra Somdej of new Niche are of hard texture with a lot of sediment covered either on one or both sides.
