A Khun Paen amulet (Phra Khun Phaen, พระขุนแผน) is a Thai Buddhist amulet named after Khun Phaen, the hero of the Thai folk epic Khun Chang Khun Phaen [1], [4]. The oldest pieces are small fired-clay votive tablets of the Ayutthaya period, most often showing a seated Buddha in the subduing-Māra pose under a pentagonal arch. The best known come from temples in Suphanburi such as Wat Ban Krang and Wat Phra Rup [4], [5].
Collectors seem to have given these tablets the Khun Phaen name in modern times [3], [4]. Monks have since made many new Khun Paen amulets, some of which depict Khun Phaen himself [4].

What does Khun Paen mean?
"Khun Paen" is a common English spelling of ขุนแผน, usually romanised as Khun Phaen; Thairath's English edition uses "Khun Paen" [7]. In the epic, the hero is first called Phlai Kaeo and later given the title Khun Phaen [1], [2]. "Khun" was a junior title given to male commoners in the old Siamese ranking system [1].
The name has a life outside the poem. English Wikipedia notes that "Khun Phaen" is shorthand for a great lover [1].
Thai collectors say phra Khun Phaen. In Chinese the epic's title appears as 《坤昌坤平》 [13].
Who is Khun Phaen? The epic Khun Chang Khun Phaen
Khun Chang Khun Phaen (KCKP) is a long Thai verse epic. It began as oral folk entertainment, probably around the seventeenth century [1]. Chris Baker and Pasuk Phongpaichit, its English translators, place its origin around 1600 [3]. Storytellers recited it in the sepha style [1]. The court later took it up and wrote it down [3]. Several chapters came from King Rama II's literary salon, and some are conventionally attributed to Rama II, the future Rama III and the poet Sunthorn Phu [1].
The plot is a love triangle. Khun Phaen is handsome but poor. Khun Chang is rich but ugly. Both want Wanthong (first called Phim) [1], [3]. Khun Phaen and Wanthong marry, but Khun Chang gets the king to send Khun Phaen to war and claims he is dead [1], [2]. The sources then differ on Wanthong's fate: Saran and Thai Wikipedia have her become Khun Chang's wife, while English Wikipedia says she goes to live with him after a quarrel with Khun Phaen [1], [2], [4]. Baker and Pasuk say only that Khun Chang takes her away [3]. In the end the king orders Wanthong executed for failing to choose between the two men [1], [3]. Most of the action takes place in Suphanburi, Kanchanaburi and Ayutthaya, and the locations are easily identifiable today [1].
Printed editions
- 1872: first printed edition, by the former missionary Samuel J. Smith [1], [3].
- 1917–1918 (2460–2461 BE): the standard three-volume edition from the Wachirayan Library, edited by Prince Damrong Rajanubhab, in 43 chapters [1], [2]. Baker and Pasuk date this edition to 1916–17 [3].
- 2010: the first complete English translation, The Tale of Khun Chang Khun Phaen, by Baker and Pasuk (Silkworm Books, Chiang Mai) [1], [4].
Prince Damrong believed the tale was based on real events of about 1500, in the reign of King Ramathibodi II [1], [2]. This is his theory, not something the record confirms.
Khun Phaen's training, weapons and spirits
In the poem, Phlai Kaeo first studies at Wat Som Yai in Kanburi. He then moves to Suphanburi and studies at Wat Palelai [3]. His teachers cover scripture, warfare, invulnerability and the raising of spirits [3]. To win Wanthong back he gets three things: a sword named Skystorm (ฟ้าฟื้น, fa fuen), a horse, and a kuman thong spirit [3], [4].
English Wikipedia describes the kuman thong spirit as made from the stillborn foetus of his own son [1]. In the version Saran summarises, Khun Phaen kills his pregnant wife Nang Bua Khli and makes the child into the spirit; he notes that another version uses the spirit of a pregnant woman [4]. Saran Suebsantiwongse of Silpakorn University calls this the first documented description of making a kuman thong. He also notes that in modern Thailand the names Khun Phaen and kuman thong have become "almost synonymous" [4].
Khun Phaen as a local hero
A 2012 Chulalongkorn University folklore thesis found that both Kanchanaburi and Suphanburi honour Khun Phaen as a local hero. Their lore includes place names, images, murals, folk songs and sacred objects (วัตถุมงคล) [12]. Kanchanaburi stresses his life as a soldier and governor, Suphanburi his temple schooling [12].
How did Buddha tablets get the Khun Paen name?
The oldest Khun Paen amulets were never made as "Khun Phaen" objects. They are phra phim (พระพิมพ์), votive tablets made by pressing clay into a mould. They were placed in stupas and temple buildings as acts of merit [3], [4].
Baker and Pasuk record that the originals were first named after the Suphanburi temple where, in their words, they were made. Later they were "enterprisingly renamed" as Khun Phaen amulets, and other production sites then used the same branding [3]. They also note that these amulets show a Buddha, not Khun Phaen, and that the Suphanburi National Museum has a large display of them [3].
Saran writes that the practice of naming tablets after Khun Phaen is unclear in origin but "seems to be a modern phenomenon" [4]. In his account, collectors named the pieces from two things: the qualities they believed the amulets had, and the place they were found. Suphanburi is Khun Phaen's home town in the epic [4]. Collectors now tend to call any Ayutthaya-period tablet of a Buddha subduing Māra under a pentagonal arch a Phra Khun Phaen [4].
Saran also links the rise in demand to two periods. Under King Rama VI (1910–1925), nationalist history celebrated warrior kings such as Naresuan. After the Second World War came a wave of crime and economic hardship, and more people sought amulets [4].
Phra Khun Phaen Wat Ban Krang, Suphanburi
Wat Ban Krang (วัดบ้านกร่าง) is in Si Prachan district, Suphanburi. It stands on the east bank of the Tha Chin (Suphan) River, opposite the district office [6]. The temple is thought to date from the middle Ayutthaya period and to be about 400 years old [5], [6]. Its ordination-hall boundary stones are carved in the shape of one of its own tablet moulds, the Song Phon Yai [5].
When the Wat Ban Krang crypt was opened
The tablets came from a chedi behind the temple's old wihan [6], [7]. Sources differ on the date:
- A 2026 study in the Journal of SaengKhomKham Buddhist Studies says, without giving its evidence, that the crypt first broke open in about 2440–2442 BE (1897–1899) [5].
- Komchadluek (2022) gives about 2447 BE, and Thairath's English edition (2026) gives about 1904, and 2447 BE is 1904 [6], [7].
The sources conflict, and this article does not choose between them. Both press accounts tell the same story. At first the tablets had no market value. Monks and villagers piled them under a large bodhi tree, and local children skimmed them across the river [6], [7]. A restored chedi behind the wihan now holds Wat Ban Krang tablets [5].
The King Naresuan legend
A local legend links the tablets to King Naresuan (r. 1590–1605) [4]. It says that after his elephant duel with the Burmese crown prince, the king's army camped on the bank of the Suphan River. There he ordered his soldiers to make 84,000 amulets and place them in the Wat Ban Krang crypt, dedicating the merit to the soldiers who had died [5], [6]. Thairath's English edition gives its own account: that the tablets were probably made in Naresuan's reign, carried by soldiers on campaign and returned to the temple afterwards [7]. In a 2010 MGR Online report, an amulet expert repeated the Naresuan attribution when dating another find [14].
The 2026 study calls a role for Naresuan and Ekathotsarot a possibility, based on the Ayutthaya style and the clay [5]. Saran suggests where the belief may come from. In Nirat Suphanburi, Sunthorn Phu (1786–1855) writes of a temple that Naresuan built where an elephant duel took place. The verse does not mention amulets [4].
Wat Ban Krang moulds (pim)
The 2026 study counts 39 mould shapes. Of these, 25 are single images and 14 are paired images joined side by side [5]. Thairath says collectors recognise more than 30 types [7]. The same study elsewhere groups the tablets into four main types, so its figures are not wholly consistent [5]. Saran reports that the Khun Phaen type is classified into nine categories by size [4]. Moulds named in the Thai press include:
| Mould (Thai) | English rendering | Source |
|---|---|---|
| ขุนแผน พิมพ์ห้าเหลี่ยม อกใหญ่ | Pentagonal, large chest | [6], [7] |
| ขุนแผน พิมพ์ห้าเหลี่ยม อกเล็ก | Pentagonal, small chest | [6], [7] |
| ขุนแผน พิมพ์ทรงพลใหญ่ | Song Phon Yai (Thairath: "Large Soldier") | [6], [7] |
| ขุนแผน พิมพ์ทรงพลเล็ก | Song Phon Lek (Thairath: "Small Soldier") | [6], [7] |
| ขุนแผน พิมพ์แขนอ่อน | Soft arm | [6], [7] |
| พลายเดี่ยว หน้าเทวดา / หน้าฤาษี | Single Phlai, deva face / hermit face | [6], [7] |
| พลายคู่ อกครุฑ / หน้ากลม | Paired Phlai, garuda chest / round face | [6] |
Thairath names the "Pentagonal Large Chest" and "Large Soldier" styles as the most popular amulets in Suphanburi [7]. Komchadluek describes the Song Phon Yai as a high-value mould [6]. A Ban Krang Khun Phaen piece shown in the Journal of the Siam Society measures 5.1 × 2.3 cm [4].
Paired tablets
Many Wat Ban Krang tablets were moulded as two images stuck together and never separated [4]. Saran suggests that collectors read these pairs as Khun Phaen's spirit children from the epic. He argues that, as art history, the two figures are more likely the Buddha's chief disciples, Moggallāna and Sāriputta [4].
Other old Khun Paen tablets: Wat Phra Rup and Wat Yai Chai Mongkhon
Wat Phra Rup, Suphanburi. Local people reportedly found small oval tablets in the temple grounds between 1965 and 1967, and the Fine Arts Department found more in a 1992 excavation [4]. Collectors call them Phra Khun Phaen Khai Pha (ไข่ผ่า, "split egg"), possibly after their shape. According to local historian Manas Opakul, they were first called Phra Lang Bia ("cowrie back") [4]. Other tablets from the same temple were also renamed after characters in the epic, such as Phra Pim Kuman Thong and Phra Pim Khun Krai [4]. One example in Saran's article measures 6.5 × 2.5 cm [4].
Wat Yai Chai Mongkhon, Ayutthaya. This royal temple is the source of two well-known types. The Khun Phaen Klueap (เคลือบ) is glazed, and the Khun Phaen Bai Phutsa (ใบพุทรา) is named for its jujube-leaf shape [4]. Looters took material from the stupas before a Fine Arts Department restoration in 1978, during which four glazed pieces were found [4].
Modern Khun Paen amulets and their makers
As demand grew, monks made new Khun Phaen amulets. Many copied the old Ayutthaya form, while others took their imagery from the poem [4]. Saran names these makers:
| Maker | Dates | Amulet | Source |
|---|---|---|---|
| Luang Pho Te Khongthong | 1891–1981 | Khun Phaen "Indochine", given to Thai soldiers sent to the Indochina wars of 1960–70 | [4] |
| Luang Pu Tim Issariko, Wat Lahan Rai, Rayong | 1879–1975 | Phra Khun Phaen Phong Phrai Kuman: a Buddha with two kneeling child figures | [4], [11] |
| Luang Pho Kuai, Wat Khositaram, Chainat | 1905–1979 | Khun Phaen Khi Hong Phrai, showing Khun Phaen himself rather than a Buddha | [4], [8] |
| Achan Pleng Bunyuen, Surin | 1917–2009 | Khun Phaen Phrai Ha Sip Kao Ton, said to contain remains from 59 corpses | [4] |
Luang Pu Tim's Phong Phrai Kuman
Luang Pu Tim (16 June 1879 – 16 October 1975) was abbot of Wat Lahan Rai in Rayong [11]. Saran dates his Khun Phaen Phong Phrai Kuman to 1975 [4]. It keeps the Ayutthaya-style Buddha in the centre and adds two kneeling figures, which Saran identifies as Khun Phaen's spirit children Phrai Pet and Phrai Bua [4]. He calls Luang Pu Tim the first master to combine a Buddha and two kuman thong figures in one Khun Phaen amulet. Later makers copied the design widely [4].
According to Saran, citing Justin McDaniel, the powder included blessed powder and ground material from a kuman thong's skull [4]. Saran treats the use of human remains in modern Khun Phaen amulets as a macabre trend, and cites Thai press reports of arrests over trade in foetal remains [4].
Where the Khun Paen love-charm reputation comes from
The reputation seems to come from the character, as Saran suggests [4]. In the poem, Khun Phaen is a soldier and an adept who uses love mantras on women and has several wives [1], [3], [4]. English and Thai Wikipedia both describe the Khun Phaen amulet as reputed for success in love [1], [2].
Sources describe the belief in different ways:
- The Penn Museum catalogues two clay amulets bought in 1985 under the name Khun Phaen. Its notes say the amulet is "used by men to attract women" [9], [10].
- Saran writes that the amulets are believed to bestow charisma, wealth and sexual attraction. He argues that their meaning moved from a Buddhist doctrinal tool towards a necromantic symbol of wealth and power [4].
- The 2026 Ban Krang study says Thai devotees link the Khun Phaen mould with sane metta mahaniyom (charm and popularity). They link Wat Ban Krang tablets in general with avoiding danger [5].
- Thairath connects a "Khun Phaen" chant (คาถาขุนแผน) of Luang Pho Kuai with love and popularity. It reports that people recite it for those aims [8].
Baker and Pasuk write that the principal benefit people look for in amulets in Thailand is protection. In a footnote they add attraction, "winning love and favor", as a further benefit of amulets [3]. These are the authors' descriptions of what wearers seek. None of the sources above tests any of these beliefs.
How collectors judge an old Wat Ban Krang Khun Paen
The 2026 Ban Krang study lists the features researchers and collectors look for in genuine old tablets [5]:
- Clay body: coarse, because mineral grains are mixed into the clay [5]. Komchadluek also notes a sandy interior [6].
- Dryness: old pieces are completely dry after long burial in the crypt [5].
- Surface sheen: a natural sheen when cleaned [5].
- Trim marks: cut marks left when the clay was trimmed from the mould [5].
- "Tamarind-flower" specks: small blood-red mineral spots in the clay [5].
- Crypt residue: traces of black fungus and marks from wooden moulds [5].
Thairath adds that colours run from red and yellow to green and black, depending on firing temperature [7]. Saran notes that rising prices led to many old types being copied, remade and consecrated by modern monks [4].
