Kutamalai (குடமலை) means western side mountain. There was an amazing painting of Kollippavai drawn on the face of the rock. Also there was a crystal clear fountain nearby, wherein bluish Kuvalai (blue waterlily) flower just in blossom.

Natrinai 192, Poet Unknown 

In Kurinji terrain the hero consoles his lady love when she feared about the dangers to be encountered on their path. O beautiful, dark lady who is pretty like the new Kolli goddess that has been installed by goblins on the west side of the mountain where beneficial jack fruit trees grow! I think about your beauty like the sun with spreading rays.  It is protection to me when I come on the mountain path!

Natrinai 201: 5 - 12, Poet Paranar,

Even if strong winds blow, even if heavy rains pour rapidly, even if thunder roars, even if many hindrances arise, even if the big earth swells up on the tall, faultless peaks in the western mountains with white waterfalls and jackfruit trees with red roots, protected by the benevolent Kolli Mountain goddess,

  Kurunthokai 100: 4-7, Kapilar, 

The girl with wide arms like bamboo is hard to embrace, and delicate like Kolli goddess who resides on the westside of strong-bowed Ori’s mountain,

ஈங்கே வருவாள் இவள் யார் கொல் ஆங்கே ஓர்

வல்லவன் தைஇய பாவை கொல் நல்லார்

உறுப்பு எலாம் கொண்டு இயற்றியாள் கொல் வெறுப்பினால்

வேண்டு உருவம் கொண்டது ஓர் கூற்றம் கொல்

Kalitokai 56: 6 - 9

Who is this girl who has come here, her face surrounded by hair braids decorated with mature clusters of blossoms from thick, shade-providing gnālal trees near the pond in the grove in town, appearing like the wide moon with sweet beams, her locks with pollen hanging low on her shoulders? There, she is like a statue made by a skilled artist.  Was she created from beautiful parts of many women?  Is she Death that attained a woman’s form due to its hatred for men?  

Sangam Polity

Tamilakam (தமிழகம்) during Sangam period was divided among the three political powers, the Cholas, Pandyas and Cheras and the three capitals were Pukar (புகார்), Madurai (மதுரை), and Vanji (வஞ்சி). They are known as crowned kings (முடியுடை மூவேந்தர்). Whenever the crowned kings conquered the feudal territories, they never annexed them to their kingdom. Instead they  allowed the feudal to function as an autonomous states under their suzerainty. Thus there were number of feudatories or chieftaincies  in Tamilakam These chieftaincies evolved as a landed aristocracy and in course of time they might have acted as soldiers, warriors, generals and even ministers to their suzerains..

Some chieftains exercised vast powers of internal autonomy within their respective territories. However they owned some kind of nominal allegiance to one or more of the the crowned kings. Number of references can be seen about the internecine warfare between the crowned kings and the vassals in Sangam literature, The reason for these feuds  could be the breaking of personal loyalty to their over-lords and refusal to pay tribute.

The chieftains are also tribal clan in character. For example Pegan belongs to Aviyar tribe or clan, Athiyan and Ori belongs to Malavar, tribe or clan. Velir chieftains ruled various parts of Tamilakam and enjoyed the privilege giving their daughters in marriage to the crowned kings. They are celebrated personalities and treated next to the crowned kings. Those chieftains who acted as the guardians of the garrisons (known as Kurumbu) in the border areas.

Seven Great Bestowers

Sirupanatruppadai, one of the Ten Idylls,  is sung on Oyman Nalliyakodan, the chieftain Oyma nadu by Nallur Nathathanar of Idaikkazhinadu, The poem lines 84 to 112 also speaks about the greatness of the Seven Great Benefactors or Bestowers or Patrons of the last Sangam era a.k.a Kadai ezhu vallalgal (கடையேழு வள்ளல்கள்) and they include: 1. Pegan of Aviyar clan (வையாவிக் கோப்பெரும் பேகன்), 2. Vel Pari, the Lord of Parambu (வேள் பாரி), 3. Kari (மலையமான் திருமுடி காரி), 4. Ay Andiran (ஆய் அண்டிரன்), 5. Athikan (அதிகன்), 6. Nalli (நளி மலை நாடன் நள்ளி) and 7. Valvil Ori (வல்வில் ஓரி). Athikan is also known as Athiyaman.

Purananuru poem 158 sung on Kumanan (குமணன்), chieftain of Mutiram hills (முதிரமலை) by Poet Perunchithiranar (பெருஞ்சித்திரனார்) also mentions about the greatness of the Seven Great Benefactors or Bestowers or Patrons of the last Sangam era a.k.a Kadai ezhu vallalgal (கடையேழு வள்ளல்கள்). Instead Athikan (அதிகன்) at srl. no. 5, the poem includes Ezhini (எழினி), the chieftain of Kutirai hills (குதிரைமலை நாடு).

Rulers of Kolli Hills

The 16 tribal counties called as "nadu" (நாடு) once constituted the historical mountain kingdom of Kolli Hills. and they include Valavanthi nadu (வாழவந்தி நாடு), Valappur nadu (வளப்பூர் நாடு), Ariyur nadu (அரியூர் நாடு), Thinnur nadu (தின்னனூர் நாடு), Guntur nadu (குண்டூர் நாடு), Selur nadu (சேளூர் நாடு), Devanur nadu (தேவனூர் நாடு), Alandur nadu (ஆலந்தூர் நாடு), Gunduni nadu (குண்டுனி நாடு), Tirupuli nadu (திருப்புலி நாடு), Edapuli nadu (எடப்புலி நாடு), Chitur nadu (சித்தூர் நாடு), Perakkarai nadu (பெரக்கரை நாடு), Peyil nadu (பெயில் நாடு), Pallappadi nadu (பள்ளப்பாடி நாடு) and Pudukombai nadu (புதுக்கோம்பை நாடு). (The 16 countries still survive and there are about 200 villages located in Kolli Hills.). Sangam literature speaks about two rulers of Kolli Hills 1. Valvil Ori (வல்வில் ஓரி), Sangam Tamil Chieftain; and 2. Perum-cheral Irumporai, the Chera ruler. Valvil Ori picked up an enmity with Perum-Cheral-Irumporai, whose capital was Karur. Ori was killed by Malayaman Tirumudi Kari in a pitched battle .Kari gave Kolli Hills as a gift to Perum-Cheral-Irumporai and the Chera succeeded after Valvil Ori's death. 

Valvil Ori

Valvil Ori  ruled over the Kolli Hills in Tamilakam around 200 A.D. He loved music and dance. Ori's swift horse was also named as Ori. His father was known as Oothan (ஊதன்). May be for this reason Vanparanar addresses him as Athan Ori (ஆதன் ஓரி):

மழை அணி குன்றத்துக் கிழவன் நாளும்

இழை அணி யானை இரப்போர்க்கு ஈயும்

சுடர்விடு பசும் பூண் சூர்ப்பு அமை முன் கை

அடு போர் ஆனா ஆதன் ஓரி

Purananuru 153, Poet Vanparanar sang for Valvil Ori

Rain-like great generosity of Ōri who never ceases to wage murderous battles, lord of a mountain decorated by clouds, wearing curved bracelets that shoot out rays, who gives awayeach day, elephants with adornments.

He was one of the Seven Great Benefactors or Bestowers or Patrons of the last Sangam era a.k.a Kadai ezhu vallalgal (கடையேழு வள்ளல்கள்). In Sirupanatruppadai (சிறுபாணாற்றுப்படை), poet Nallur Nathathanar of Idaikkazhinadu (இடைக்கழி நாட்டு நல்லூர் நத்தத்தனார்) eulogizes Valvil Ori in the poem lines 107 - 111.

…………………….. நளி சினை

நறும் போது கஞலிய நாகு முதிர் நாகத்து

குறும் பொறை நல் நாடு கோடியர்க்கு ஈந்த

காரிக் குதிரைக் காரியொடு மலைந்த   

ஓரிக் குதிரை ஓரியும் 

(Sirupanatruppadai  107 - 111, Poet Nallur Nathathanar of Idaikkazhinadu)

Ori, owner of a horse named Ōri, who donated to dancers and musicians, fine lands with hills and young, tall surapunnai trees with dense branches bearing fragrant, bright flowers.  He fought with Kari who rode on a horse named Kari.

In Purananuru poem 158 poet Perunchithiranar praises about Valvil Ori in the poem line 5. The chieftain Valvil Ori ruled Kolli Hills.

கொல்லி ஆண்ட வல்வில் ஓரியும்

(Poet Perunchithiranar sang to Kumanan. Purananuru 158: 5)

Valvil Ori ruled Kolli Hills.

He was known for his rain like generosity (மாரி வண் கொடை). He was the 'lord of a mountain decorated by clouds and known for his murderous battles. He is popularly known for his skill in archery and therefore he was named as "Valvil Ori" meaning "great skill in archery." Vanparanar, a Sangam poet eulogises Ori's archery skill in Puranauru poem 158. Ori shot an arrow from his bow. The arrow struck down an elephant, further it went and killed a tiger, dropped a spotted stag, felled a boar and embedded in an iguana in a nearby deep hole.

வேழம் வீழ்த்த விழுத் தொடைப் பகழி

பேழ்வாய் உழுவையைப் பெரும் பிறிது உறீஇப்

புழல் தலை புகர்க் கலை உருட்டி உரல் தலைக்

கேழல் பன்றி வீழ அயலது

ஆழல் புற்றத்து உடும்பில் செற்றும்

வல் வில் வேட்டம் வலம்படுத் திருந்தோன்

புகழ் சால் சிறப்பின் அம்பு மிகத் திளைக்கும்

Purananuru 152, Poet Vanparanar sang for Valvil Ori, 

He was widely famed for his skill in killing, the one who shoots with his strong bow.  He shot an arrow that felled an elephant, killed a tiger with gaping mouth, dropped a spotted stag with hollow horns, felled a boar with head like mortar, and embedded in a monitor lizard in a nearby deep hole.  Who is the archer who shoots with such skill? 

Each day he gave away elephants with adornments. One bard sang vannam compositions on Ori. The danseuse (virali) accompanying the bard played mula drum, ellari drum, akuli drum, pathalai drum, liitle lute, and thoompu as orchestra. Twenty  one themes of musical compositions were composed in honour of Valvil Ori (Purananuru 152). Ori gifted the bards and their accomplices with water lily flower made in gold inset with sapphires and fastened to silver threads, wealth, and herds of elephants. The bards who called on Ori were not starving any more and remained without dancing to the sweet music instruments. (Purananuru 153)

Ori was eulogized for his generosity and valour in five of the eight anthologies (Ettuthokai) books such as Akananuru (அகநானுறு), Kuruntokai (குறுந்தோகை), Natrinai (நற்றிணை), Pathitrupathu (பதிற்றுப்பத்து) and Purananuru (புறநானுறு) as well as in one of the Ten Idylls (பத்துப்பாட்டு) book - Sirupanatruppadai (சிறுபாணாற்றுப்படை). Sangam poets such as Arisil Kizhar (அரிசில் கிழார்), Ilankiranar (இளங்கீரனார்), Avvaiyar (ஔவையார்), Kapilar (கபிலர்), Kalladanar (கல்லாடனார்), Kurunkozhiyur Kizhar (குறுங்கோழியூர் கிழார்), Thayankannanar (தாயங்கண்ணனார்), Paranar (பரணர்), Perunkunrur Kizhar (பெருங்குன்றூர் கிழார்), Perunchitranar (பெருஞ்சித்திரனார்), Mathurai Alakkar Gnazhalar Makanar Mallanar (மதுரை அளக்கர் ஞாழலார் மகனார் மள்ளனார்) lauded Kolli Hills and Ori. Kapilar, Nattattanaar, Paranar and Perunchitranar eulogise Valvil Ori as the benevolent ruler of Kolli Hills. Kurunkozhiyur Kizhar, Perunkunrur Kizhar and Thayankannanar glorify the Kolli Hills.

Perum-cheral Irumporai

Perum Cheral Irumporai (பெருஞ்சேரல் இரும்பொறை), the Chera monarch was the son of Selvak Kadungo Vaazi Adan (செல்வக்கடுங்கோ வாழி ஆதன்).  Eighth decad of Patitrupattu anthology narrates his seventeen years of rule. He ruled his country from Karur, the Chera capital (கருவூர் ஏறிய ஒள்வாட் கோப்பெருஞ்சேரல் இரும்பொறை). The siege of Karur by the Chola monarch Kulamutrathu Thunjiya Killivalavan (குலமுற்றத்துத் துஞ்சிய கிள்ளி வளவன்) developed a pitched battle and the Chera won the battle and assumed the title "Ko-Perum-cheral-Irumporai (கோப்பெருஞ்சேரல் இரும்பொறை). Athiyaman of Tagadur was under the overlordship of Cheras. When Athiyaman failed to accept the authority of Cheras, Perum Cheral Irumporai defeated him in a pitched battle. His invasion, destruction and victory of the city of Tagadur of Athiyaman chief Ezhni is mentioned in Tagadur Yathirai (தகடூர் யாத்திரை), a literary work and Irumporai was known as Tagadur Erintha Perum Cheral Irumporai (தகடூர் எறிந்த பெருஞ்சேரல் இரும்பொறை).

Malayaman Tirumudi Kari

Malayaman Tirumudi Kari was one of the autonomous chieftain who ruled Malainadu.  Tirukovalur, an ancient town, was his capital.  Mullur (now located in Gingee taluk, Villupuram district) was the most important town in his country. முள்ளூர் மன்னன் கழறொடிக் காரி (Akananuru 209). Kotunkal (கொடுங்கல்)  was another town of Kari located on the banks of the river Pennai. He was one of the Seven Great Benefactors or Bestowers or Patrons of the last Sangam era a.k.a Kadai ezhu vallalgal (கடையேழு வள்ளல்கள்). He was also one of the contemporary of Valvil Ori. Sirupanatruppadai (lines 91 - 95) and Purananuru poem 158 (lines 6 - 7) eulogise Tirumudi Kari.

The chieftains were subdued by the empire builders i.e., Muvendars - Chera, Chola and Pandya of ancient Tamilakam and their paramountcy was accepted. Kari was a vassal to the early Chola king Kulamutrathu Thunjiya Killivalavan. Over the period of time he broke his loyalty to the over-lord and wore a crown and declared himself as Tirumudi Kari. He was a revolting vassal and was one of the most dangerous threats to the crowned king and neighboring vassals.

Kari - Athiyaman Neduman Anci: Encounter

Athiyaman Neduman Anci was the chief of the renowned warrior clan of Malavar. Tagadur was his capital (identified with modern Dharmapuri district). Kari waged war on Tagadur against Athiyaman Neduman Anci. It was an attempt fueled by his longtime desire to become an emperor equivalent in power to the Cholas. Kari was defeated and lost Kovalur to Athiyaman.

Kari Defeated Valvil Ori 

Perum Cheral Irumporai was in agreement with Malayaman Tirumudi Kari and the Chera was expecting Kari's support in defeating Valvil Ori (வல்வில் ஓரி), the chieftain of Kolli hills (கொல்லிமலை). Kari defeated and killed Ori and took Kolli Hills. An Akananuru poem 209 and Natrinai poem 320 register this event.

முள்ளூர் மன்னன் கழல்தொடிக் காரி

செல்லா நல்இசை நிறுத்த வல்வில்

ஓரிக் கொன்று சேரலர்க்கு ஈந்த (Akananuru 209)

Mullur King Kari with warrior anklets and bracelets, owning bloody spears, gifted to the Cheras after killing Ori of unfading fame and strong bows.

"ஓரிக்கொன்றவொருபெருந் திருவிற், காரி புக்க நேரார் புலம்போற், கல்லென் றன்றாலூரே" (Natrinai.320 Poet Kapilar)

The whole town laughs with great uproar. This is like when Kāri killed Ori of ancient victories, and then entered his wide avenue which had no match, and his people raised uproars.

Kari captured the Kolli Hills and gifted it to Perum Cheral Irumporai (Akananuru poem 209). Perum Cheral Irumporai on his part defeated and killed Athiyaman and retrieved Tirukovalur and handed over to Kari. The capture of Kollik-kuurram (கொல்லிக்கூற்றம்)  and Tagadur (தகடூர்) by the Irumporai and the pitched battles are vividly referred in Patirruppattu anthology. From then on Paranar commenced addressing the Chera as "Perum Cheral Irumporai, as the Lord of Kolli hills."(who is also known as Poraiyan)  and as "Poraiyan Kolli" (பொறையன் கொல்லி) (ref. Akananuru poem 82 and Kuruntohai poem 89). Kolli-kutavarai belongs to Cheras who won battles ‘வெல்போர் வானவன் கொல்லிக் குடவரை’ (Akananuru 213). Silappatikaram also praises Perum-cheral Irumporai as the Lord of Kolli Hills (‘கொல்லியாண்ட குடவர் கோவே’)(ref. Silappadhikaram Pattumadai Chapter 24-verse 26). This suggests that Silappatikaram could have composed after Cheras captured Kollik-kuurram (கொல்லிக்கூற்றம்). 

கழை விரிந்து எழுதரும் மழை தவழ் நெடுங்கோட்டுக்

கொல்லிப் பொருந கொடித் தேர்ப் பொறைய!

Patirruppattu 73;11, Poet Arisil Kilar king Perum Cheral Irumporai

Lord of the mountain country with banners on your chariots! You are the king of Kolli Mountain where bamboo forests rise high, and clouds spread on tall peaks.

His successor Cheraman Yanaikat Chey Mantharan Cheral Irumporai (யானைக்கட்சேய் மாந்தரஞ்சேரல் இரும்பொறை) is being addressed by  Poet Kurunkoliyur Kilar as "O killer King!  Ruler of Kolli Mountain!" ஓங்கு கொல்லியோர் அடு பொருந (Purananuru 22).
