Dragon slayings#
Dragons are mythical monsters that look like giant reptiles. The etymology of the word suggests that dragon is derived from the Greek word drakōn, which means snake [1]. Snakes have, from the earliest times, been feared because of their human-killing venomous bite. It was easy for the ancients to imagine anything fearsome and cruel to be a dragon, and any person overcoming or killing such a menace to be a hero, worthy of adulation.
The stories#
Here are five stories about killing dragons. These stories have been handed down through generations by means of oral tradition and folklore, and are from the region that lies between India and Italy.

Indra and Vritra (India)#
There was once a demon called Vritra. He went and stole the cows of the gods and hid the cows in a cave. He then deployed his army of the Panis to guard the cave.
Upon discovering that their cattle was missing, the gods sent their dog, Sarama, to look for the cows. Sarama located the cave where the cows were hidden, and, acting as a messenger of the gods, asked the Pani guards to hand the cattle over to her. The Panis refused. Instead, they made an offer: if Sarama would switch over to the side of the Panis, they would make her their sister and also the owner of the cattle. Sarama refused, went back to the gods, and revealed the location of the cave [2].
Thereupon, Indra, the king of the gods, gathered his army around, fortified himself with Soma, and marched against Vritra and his Pani troops. Indra took up his thunderbolt and hurled it towards Vritra with a huge roar. The thunderbolt struck Vritra down dead, and split open the mountain that was concealing the cattle herd, who ran out, lowing, towards the waiting gods.
The Rig Veda describes this event several times. For example, see the following verses:
Indra’s deed
Indra destroyed Vritra, the lurking demon, and made manifest the stolen kine hidden in the night [3].
Indra, the slayer of Vritra, shakes the hiding place of the numerous herd of kine [4].

Trita Aptya and Trishira (India)#
There were once three boys named Eka, Dvita, and Trita. They were the sons of Agni and born from the waters. Once, when the three brothers were going somewhere in quest of money, Trita was pushed into a well by his two brothers, who then covered the well with a cartwheel and went away, leaving their brother to die.
Trita, by DALL-E#
Trita prayed to the gods, and with their help, threw open the wheel covering the well and came out. He then proceeded to learn the martial arts and claim his ancestral weapons [5].
So, this was Trita.
Then, there was Trishira, the three-headed son of Tvashti (master forger of the gods). With one of his heads, Trishira had his food, with the second, he drank the Soma juice, and with the third, he recited the Vedas. Trishira was a guardian of cows.
Trishira, by DALL-E#
Indra, the king of the gods, became fearful of Trishira. He thought that someone as powerful as Trishira might depose him and sieze the throne of heaven. Indra, therefore, wanted Trishira dead. For this purpose, he incited Trita, who then killed Trishira and released his cows [6]. The wind gods helped Trita in this battle. The event is described in the following manner in the Rig Veda:
Thraetaona and Azi Dahâka (Persia)#
Azi Dahâka was a three-headed, deceitful monster that was created by the dark force called Angra Mainyu.
Seeking a boon that he may clear the world of humankind, the monster performed a sacrifice to the goddess Anâhita:
Azi Dahâka prays to Anâhita
To her did Azi Dahâka, the three-mouthed, offer up a sacrifice…
“Grant me this boon, O good, most beneficent Ardvi Sûra Anâhita! that I may make all the seven Karshvares of the earth empty of men.”
Ardvi Sûra Anâhita did not grant him that boon [9].
Anâhita did not grant Azi Dahâka his boon. Instead, she blessed Thraetaona, son of Athwya, who begged of her a boon that he may kill Azi Dahâka and set free the monster’s two wives.
Thraetaona prays to Anâhita
…that I may overcome Azi Dahâka, the three-mouthed, the three-headed, the six-eyed, who has a thousand senses, that most powerful, fiendish Drug, that demon, baleful to the world, the strongest Drug that Angra Mainyu created against the material world, to destroy the world of the good principle; and that I may deliver his two wives, Savanghavâk and Erenavâk, who are the fairest of body amongst women, and the most wonderful creatures in the world [10].
His wish having been rejected by Anâhita, Azi Dahâka now prayed to the god Vayu:
Azi Dahâka prays to Vayu
Grant me this, O Vayu! who dost work highly, that I may make all the seven Karshvares of the earth empty of men [11].
But Vayu, too, did not grant Azi Dahâka his request. Instead, just like Anâhita had done, Vayu too granted Thraetaona his wish that he may gain victory over Azi Dahâka.
Thraetaona prays to Vayu
Grant me this, O Vayu! who dost work highly, that I may overcome Azi Dahâka, the three-mouthed, the three-headed, the six-eyed, who has a thousand senses, that most powerful, fiendish Drug, that demon baleful to the world, the strongest Drum… [12]
Fortified with the boons and blessings of Anâhita and Vayu, Thraetaona then defeated Azi Dahâka, and bound him to the mountain Damavant. It is said that the monster will remain there, bound, till the end of the world, when he’ll be finally killed by Keresâspa.
The exploit of Thraetaona is described in the Zend Avesta in the following manner:
Thraetaona’s deed
Athwya, was the second who prepared me for the corporeal world.
This blessedness was given him, this gain did he acquire, that to him a son was born, Thraetaona of the heroic tribe, who smote the dragon Dahak, three jawed and triple-headed, six-eyed, with thousand powers, and of mighty strength, a lie-demon of the Daevas, evil for our settlements, and wicked, whom the evil spirit Angra Mainyu made as the most mighty Drugk against the corporeal world, and for the murder of our settlements, and to slay the homes of Asha [13].
Keresâspa, who is earmarked for killing Azi Dahâka at the end of time, is none other than the son of Thrita, and has overpowered many monsters and evil beings. This is described in the Zend Avesta in the following manner:
Who is Keresâspa
…youth of great ascendant, ringlet-headed, bludgeon-bearing. He who smote the horny dragon swallowing men, and swallowing horses, poisonous, and green of colour, over which, as thick as thumbs are, greenish poison flowed aside, on whose back once Keresâspa cooked his meat in iron caldron at the noonday meal… [14]
Keresâspa, by DALL-E#
Vahagn and Azhdahak (Armenia)#
Vahagn belongs to the Armenian gods trinity, along with two other gods, namely, Armazd and Anahit. In Yerevan, Armenia, there’s a huge rock-cut statue of the god Vahagn killing a serpent dragon.

Much of Armenia’s folklore has been lost after its changeover to Christianity, but the country has long had an oral tradition about Vahagn dragging serpents and monsters out of Lake Van and throwing them up to the sun to be burnt to death [15].
The story about killing the monster Azhdahak is recounted in a song by Moses Khorenatsi [16], which begins by describing the god’s birth in the following manner:
Vahagn’s birth
In travail were heaven and earth,
In travail, too, the purple sea!
The travail held in the sea the small red reed.
Through the hollow of the stalk came forth smoke,
Through the hollow of the stalk came forth flame,
And out of the flame a youth ran!
Fiery hair had he,
Ay, too, he had flaming beard,
And his eyes, they were as suns!
The song goes on to say that Vahagn killed Azhdahak, and is called Vishapakagh because he killed dragons [17] (in the Armenian language, vishap means ‘sea dragon’ and akagh means ‘slayer’).
Hercules and Cacus (Italy)#
Cacus was a fire-breathing monster who lived in the caves around Rome and terrorised the countryside. The entire area around his cave was littered with the heads, bones, and carcasses of the men and animals he had killed and eaten, and the ground was stained with their blood.
Once, it so happened that the hero Hercules, who was shepherding the cows of Geryon to the court of King Eurystheus, stopped to rest near this place. He pastured the cattle at a meadow and went to sleep. As Hercules slept, the monster Cacus was drawn to that place by the sound of the herd. Cacus came down to the meadow and stole away four cows and four bulls, took them to his cave, and barred the entry with a huge boulder.
When Hercules awoke and learnt what had happened, he went up to Cacus’s cave to recover the cattle. Being unable to enter the cave, he broke open the mountain top, reached inside and pulled Cacus out, throttled the monster to death, and freed the cows. This entire story is described by Virgil in Chapter VIII of The Aeneid in the following manner:
Hercules smashes a mountain
The hero stood
Adverse, with planted feet, and, from the right,
Tugg’d at the solid stone with all his might.
Thus heav’d, the fix’d foundations of the rock
Gave way; heav’n echo’d at the rattling shock.
Tumbling, it chok’d the flood: on either side
The banks leap backward, and the streams divide.
…
The monster, spewing fruitless flames, he found;
He squeez’d his throat; he writh’d his neck around,
And in a knot his crippled members bound;
Then from their sockets tore his burning eyes:
Roll’d on a heap, the breathless robber lies.
The doors, unbarr’d, receive the rushing day. [18]
The comparison#
Linguistic analysis#
Are there any connections between the words in the myths?
In the Indra-Vritra myth, the name Vritra is used interchangeably with Vala and Ahi, as seen in the following verses from the Rig Veda:
Vritra is Vala; Vritra is Ahi
You, wielder of the thunderbolt, did open the cave of Vala, who had there concealed the cattle; and the gods whom he had oppressed, no longer feared when they had obtained you as their ally [19].
Indra, you have set free the waters that were formerly arrested by Ahi [20].
Priests! Offer the drink to Indra, who slew the rain-arresting Vritra [21].
The Sanskrit Ahi is cognate with the Iranian Azi [22] and Armenian Azh (օձ) [23], all of which mean a ‘snake’.
The name of the villain is very similar in the Iranian (Azi Dahâka) and Armenian (Azhdahak) myths.
The Sanskrit suffixes -ghn and -han are cognate with the Iranian -gn and Armenian -akagh, all of which mean a ‘destroyer or remover of obstacles’. Indra is often referred to as Vritraghn and Vritrahan, while Vahagn is called Vishapakagh.
Trita of the Trita-Trishira myth can be said to bear a phonetic similarity to the Iranian Tishtrya who fights against the demon Apaosha (drought) and pours liberating rain upon the earth [24]. However, this aspect needs to be examined in much more detail before a linguistic similarity can be drawn between Trita and Tishtrya.
Here’s a tabulation of the cognate words from the five myths.

From a linguistic standpoint, it seems that the Hercules-Cacus myth is an outlier. However, in the ancient Greek language, the word Cacus (κακός) means bad or evil [28], and some research is needed to see whether the Iranian and Armenian Dahak are cognate with Cacus.
It also seems that, linguistically, the Trita-Trishira myth belongs only tentatively to the group through its connection to the Thraetaona-Azi Dahâka myth by the ‘water’-word Ap. Keresâspa, who will kill Azi Dahâka at the end of time, is the son of Thrita. Further research is needed to see whether this Thrita is related to Trita.
The other three myths, namely, the Indra-Vritra myth, the Thraetaona-Azi Dahâka myth, and the Vahagn-Azhdahak myth, have several linguistic similarities among them.
Psychological analysis#
Are there any common motifs or behavioural pattern in the actors and scenes in these myths?
The following two archetypes can be used for analysis:
The archetype of good-versus-evil
The archetype of the hero
In the Indra-Vritra myth, Indra is the hero who, aided by other gods, kills the evil Vritra who has imprisones the cows (which is an analogy for obstructing the rainwaters) and has, as a result, brought drought upon the earth. Vritra has been repeatedly called a demon. Azi Dahâka is evil personified as he openly declared his intention of ridding the world of humans, and it needs two heroes to overcome him, namely, Thraetaona, who chains him up, and Keresâspa, who will kill him. Vahagn is a hero who plays with evil dragons. Hercules heroism lives so long that when he dies, he is turned into a star by his father Zeus [29]. It is only in the Trita-Trishira myth that an archetype is not evident; the story seems to be one of petty jealousy on the part of Indra who then incites Trita to kill Trishira, and contains neither a hero archetype nor a good-versus-evil archetype.
Here’s a tabulation of the archetypes in these myths.
Indra - Vritra |
Trita - Trishira |
Thraetaona - Azi Dahâka |
Vahagn - Azhdahak |
Hercules - Cacus |
|
|---|---|---|---|---|---|
Hero archetype? |
Yes |
No |
Yes |
Yes |
Yes |
Good-versus-evil archetype? |
Yes |
No |
Yes |
Yes |
Yes |
From a psychological standpoint, therefore, the Trita-Trishira myth does not belong to the same class as the other four myths.
Structural analysis#
What’s the plot?
All of these myths have a common basic structure of a three-headed being who is killed by a god or demigod.
In all these cases, except in the Trita-Trishira myth, this three-headed being lives inside a cave or likes to hide in a mountain or inside a lake. The antipathy to light and open spaces is evident.
In all these cases, except in the Vahagn-Azhdahak myth, cattle is involved.
In all these cases, except in the Trita-Trishira myth, a water body is involved: the cows in the two Vedic stories are euphemisms for water - whether rain or river [30] - and the serpent [31] and its cave is a personification of clouds [32] that obstruct the light (‘light’ is another word for ‘cow’ [33]) and waters; Trita is called Aptya because he’s a son of water; Thraetaona’s father, Athwya, is related to water too, as is Vahagn who, besides being born of the water, also drags serpents out of the waters of Lake Van and kills them; Hercules’s breaking of the mountains to bring out Cacus resulted in the rivers breaching their banks.
The structural similarities among these myths can be tabulated in the following manner.
Indra - Vritra |
Trita - Trishira |
Thraetaona - Azi Dahâka |
Vahagn - Azhdahak |
Hercules - Cacus |
|
|---|---|---|---|---|---|
Victor is a god? |
Yes |

Mountains are involved? |
Yes |
No |

From a structural standpoint, it looks like the Trita-Trishira myth is an outlier for this group, and is structurally not really similar to them except for the part about the vanquished being a three-headed being.
Historical analysis#
Historical evidence for Indra and Trita are non-existent.
Because of the pervading cultural influence of Iran over Armenia for a very long time, the Iranian Verethergn became the Armenian Vahagn [34]. In later Armenian lore, Vahagn is a king who had once been worshipped as a god, and from whom the hereditary high priests of Armenia claimed descent [35]. In the Hellenic times, Vahagn was linked to Hercules.

The monuments at Mount Nemrut, Turkey, erected by Antiochus I Theos of Commagene [36], show that both the Iranian Verethregn (Thraetaona) and the Armenian Vahagn were identified with Hercules [37].
From a historical perspective, therefore, it would seem that the myths of Thraetaona, Vahagn, and Hercules are related. However, there is no historical evidence for the actual existence of these heroes.
Naturalistic analysis#
Do any natural elements find place in these myths?
Trita is connected with water by his very name Aptya (meaning, ‘born of water’). Also, Trita (meaning, ‘third’) is the third form of the god of fire, which is the lightning that releases the pent-up waters in the clouds [38]. Indra, too, is a lightning-wielder and brings down dark ‘clouds’ from the sky so that the waters can be released. Both these gods are helped by the wind gods when they pierce the cloud mountains. Thus, both Trita and Indra can be said to be manifestations of the natural phenomenon of lightning.
Trita and Thraetaona are both linked to fire. Thraetaona has later been called Behram [39]. Whether the Iranian fire, known as Atash-e-Bahram (meaning, ‘the fire of Behram’) is in any way related to Trita, Thraetaona, or the natural event of lightning, needs further research.
The myths of Vahagn and Hercules do not seem to show any connection with any natural phenomenon.
Phylogenetical analysis#
History begins where myths end. How did these myths change over time?
Indra and Trita both kill a demon, and both are helped by the wind gods. Trita was a god in the times of the Rig Veda but by later vedic times, Trita was only a rishi [40]. In quite a few places in the Rig Veda, Trita is also associated with Soma, the drink of the gods [41]. He is seen as preparing the Soma and offering it to the gods. While Indra (along with Agni) has the maximum number of verses in the Rig Veda addressed to him, there are about only forty Rig Veda verses that mention Trita and, in many of them, he is only the poet and not the god being invoked. It would seem that, over a period of time, Trita’s god-ness was appropriated by Indra [42].
Trita kindled fire and brought it to earth [43]. In this function, he is similar to the Iranian Thraetaona, also called Verethregn, who, in later Iranian lore, became Behram [44].
Thraetaona’s father Athwya is someone who prepares the Haoma, just like Trita (also called Aptya) is seen preparing the Soma in the later Rig Vedic hymns. Whether Trita and Athwya are related needs to be studied further.
Thraetaona of the Zend Avesta becomes, in later Persian literature, a prince called Faridun who battles with a cruel king named Zahhak, whose evilness stemmed from two snakes that lived on his shoulders. Faridun gathers an army, marches against Zahhak, is helped in his quest by the two sisters of Jamshid, defeats Zahhak, and ties him up in the Damawand mountains [45]. Whether this later story (composed around the 11th century AD) is in any way related to the myth of the Iranian Jamshid and Yima (both of whom are connected to light and sun) needs further research.
Conclusion#
Taking into consideration the analysis outlined in the preceding paragraphs, a comparison of these five myths can be tabulated as follows:
Indra - Vritra |
Trita - Trishira |
Thraetaona - Azi Dahâka |
Vahagn - Azhdahak |
Hercules - Cacus |

It can be seen from this table that a fair amount of correlation exists between the myths of Indra-Vritra, Thraetaona-Azi Dahâka, and Vahagn-Azhdahak.
It is also seen that a fair amount of correlation exists between Thraetaona, Vahagn and Hercules, and between the Indra and Trita. It might be interesting to study whether there is any correlation between Trita and Thraetaona.
From the myths themselves, it might not be erroneous to say that the people (and the civilisation) of Armenia, Iran, and India might have, at some extremely antiquated time, either had a common ancestor group or were so interwoven socially that their conception of divinity and evil had very similar shades that differed only slightly. It might also not be erroneous to say that when some of these regions started believing in a newer god-system, they sought to merge or assimilate their existing stories into the new myths that were thenceforth propagated.
A fuller study of these myths, with focus on the following points will surely reveal interesting links:
Whether the Iranian and Armenian Dahak is cognate with the Roman Cacus
Whether the Iranian Thrita, father of Keresâspa, is related to the Indian Trita
Whether Atash-e-Bahram is related to Trita, Thraetaona, or the natural event of lightning
Whether the Faridun story is related to the Iranian myth of Jamshid/Yima
Whether the Iranian Thraetaona is related to the Indian Trita
