Chronological History & Archaeology of Thai Votive Tablets (Phra Phim to Phra Kreuang)
From 6th-century Dvaravati terracotta pilgrim tokens and Hariphunchai crypts to the BE 1967 Wat Ratchaburana Ayutthaya warrior vaults and Somdej Toh's Rattanakosin chalk tablets.
1. Dvaravati, Srivijaya & Hariphunchai Origins (6th–13th Century CE)
The earliest votive tablets in Thailand—known archaeologically as Phra Phim (พระพิมพ์)—were not worn around the neck.
Modeled on Indian Gupta and Pala terracotta pilgrim tokens from Bodh Gaya and Nalanda, they were stamped from riverine clay or sun-baked ash and deposited inside brick stupas (Chedis) or limestone caves to ensure the continuation of the Buddhist Sasana into future millennia.
In the northern Mon kingdom of Hariphunchai (modern Lamphun), artisans refined alluvial clay through fine cloth and fired it at high kiln temperatures, producing miniature masterpieces such as Phra Rod of Wat Mahawan and Phra Kong.
2. Lopburi, Sukhothai & Ayutthaya Warrior Crypts (10th–18th Century CE)
During the Lopburi (Khmer Bayon) and Sukhothai periods, metallurgy advanced into cast lead-tin-mercury alloys (Nuea Chin Ngern and Nuea Chin Takua).
By the U-Thong and Ayutthaya eras, votive tablets transitioned from purely commemorative stupa deposits (Phra Kru) into portable objects distributed to soldiers prior to military campaigns.
In BE 1967 (1424 CE), King Borommarachathirat II (Chao Sam Phraya) sealed the three-level underground crypt of Wat Ratchaburana in Ayutthaya containing royal gold regalia and over 100,000 lead-tin and terracotta tablets.
3. The Rattanakosin Revolution: Somdej Toh & The Era of Struck Medallions
Between BE 2409 and BE 2415 (1866–1872 CE), Somdej Phra Buddhacharn (Toh Phromrangsi) of Wat Rakhang Kositaram transformed Thai amulet culture by compounding the Five Sacred Chalk Powders (Phong Wised) into hand-pressed rectangular tablets distributed directly to lay devotees.
Three decades later, European hydraulic coin presses introduced struck metal medallions (Rian), beginning with Rian Phra Phuttha Chinnasee (BE 2440) and the first monastic portrait medallions (Rian Phra Geji) in BE 2458–2460.
