The Horse’s Reins in the Hymns: What the Lexicon 'Aśva' Reveals About Late Harappan Agro-Pastoralism

The Sanskrit noun aśva (horse) belongs to an ancient Indo-European lexical lineage. It traces back to the reconstructed Proto-Indo-European root *h₁éḱwos (swift animal). Cognates appear across ancient Indo-European tongues: Avestan aspa, Latin equus, Old English eoh, and Ancient Greek hippos.

In the Rigveda (the oldest collection of Vedic Sanskrit hymns), aśva appears over 200 times. The text depicts horses bound to spoked-wheel chariots, steered by harness hardware, and offered in royal sacrifices like the aśvamedha.

This dense equine imagery contrasts sharply with the material record of the Urban Harappan phase of the Indus Valley Civilization. Mature Harappan stamp seals show dozens of wild and domesticated animals, from humped bulls to rhinos. They show no true horses.

Reconciling this textual dominance with Bronze Age archaeology requires tracking both the philology of equine control and the faunal bone record of the Late Harappan period.

Philology of Control: Harnesses and Reins

Vedic poets did not merely write about wild horses. They documented specialized gear used to direct tamed animals.

In the Rigveda, words like raśmi (rein or strap) and pragraha (bridle or rein) describe the physical tie between human driver and draft animal. Hymns depict gods and warriors holding raśmi to steer paired horses attached to lightweight vehicles.

Comparative historical linguistics shows that early Indo-European horse terminology was closely tied to wheeled technology. Historical linguists reconstruct terms for axle, wheel, nave, and yoke across the language family.

Evidence shows that aśva in the Rigveda consistently functions alongside this wheeled transport apparatus. The hymns describe bits placed in mouths, whips laid upon flanks, and reins held tight to govern momentum.

Scholars debate whether the earliest Rigvedic passages reflect mounted riding or vehicle driving. Some verses, such as Rigveda 5.61.2–3, describe figures with seats on animal backs and reins attached to noses. But the dominant paradigm in the text remains the horse-drawn two-wheeled chariot.

The Archaeozoology of the Equid Bone Record

The archaeological search for early South Asian domestic horses (Equus caballus) centers on bone fragments and tooth enamel.

The native wild equids of the northwestern subcontinent are Equus hemionus khur (the Indian wild ass or onager). Distinguishing the skeletal fragments of Equus caballus from Equus hemionus requires specific morphological markers on cheek teeth and phalanges.

In 1997, Hungarian archaeozoologist Sándor Bökönyi examined bone specimens from the site of Surkotada in Kutch, Gujarat. He concluded that six specimens from third-millennium BCE layers belonged to true domestic horses.

However, archaeozoologists Richard H. Meadow and Ajita Patel re-examined the same Surkotada material. They disputed Bökönyi’s identification, arguing the measurements fell within the natural variation of local wild asses (khur) or half-asses.

Evidence shows that verified skeletal remains of Equus caballus appear in the South Asian archaeological record during the second millennium BCE. Uncontested horse bones and equine figurines turn up in the Swat Valley (Ghalegay IV and V phases) and northern pastoral sites dating between 1600 BCE and 1200 BCE.

Late Harappan and Cemetery H Transitions

The decline of the urban Indus centers around 1900 BCE ushered in the Late Harappan period. Populations moved away from large urban centers like Mohenjo-daro toward regional agro-pastoral networks.

In the Punjab plains, this phase overlaps with the Cemetery H culture. Material culture shifted from standardized weight systems and stamp seals to regional pottery forms and modified burial practices.

Archaeological evidence shows that pastoral groups along the northern edge of the subcontinent adopted horses during this post-urban transition. The entry of aśva coincided with changes in transport technology across Central and South Asia.

Rather than replacing existing agricultural systems overnight, horse pastoralism integrated into local agro-pastoral traditions. Late Harappan communities relied on cattle, sheep, and barley cultivation. Domestic horses served as high-status transport animals rather than primary traction beasts for farm plows.

Synthesizing Text and Material Evidence

Philological research demonstrates that the Rigveda preserves an archaic Indo-European vocabulary centered on horse control. Archaeozoology confirms that true domestic horses were absent from early urban Harappan layers and appeared in the regional archaeological record during the second millennium BCE.

Scholars debate the exact pathways and timelines by which Indo-Aryan language speakers brought horse-centered pastoralism into the subcontinent.

Textual philology shows that terms like aśva and raśmi arrived as part of a complete lexical system. Fauna analysis shows that horses integrated into South Asia during the Late Harappan reorganization, aligning the linguistic horizon with the material record of the Bronze Age.
