Satavahana Naval Dominance: Lead Ship-Coins of Yajna Sri Satakarni, Coromandel Ports & Deccan Greco-Roman Commerce

Last updated: August 13, 2026 | 13-minute read

Executive Summary: Reigning over the Deccan peninsula between the 2nd century BCE and the 3rd century CE, the Satavahana Empire (Andhras) established unprecedented bi-coastal maritime supremacy spanning both the Western Arabian Sea (Bharuch / Kalyan / Sopara) and the Eastern Bay of Bengal (Arikamedu / Dharanikota / Ghantasala). Under the illustrious Emperor Gautamiputra Yajna Sri Satakarni (circa 174–203 CE), the imperial treasury minted iconic lead and potin coins bearing the raised relief of double-masted, ocean-going rigged warships equipped with rudders and steering oars, celebrating Satavahana naval power and dominion over the thriving Greco-Roman and Southeast Asian trade routes.

🪙 1. The Numismatic Masterpiece: The Double-Masted Ship Coins

Discovered primarily along the Coromandel coast (between Chennai, Cuddalore, and Machilipatnam), the ship-type coins of Yajna Sri Satakarni and Vasishthiputra Pulumavi represent the most detailed contemporary visual evidence of ancient Indian naval architecture:

+---------------------------------------------------------------------------------------------------+
 Obverse: Double-Masted Ocean-Going Rigged Vessel
 • Two vertical masts rigged with cross-spars (yardarms) for large square sails
 • Elevated, pointed bow (prow) designed to slice open ocean swells
 • Stern equipped with twin steering oars (quarter rudders) for deep-sea navigation
 • Wave symbols beneath hull indicating high-seas oceanic journey

                                                ▼
 Reverse: Sacred Ujjain Symbol (Four-Circle Cross) + Six-Arched Hill (Chaitya) with River Wave
 • Inscribed in Prakrit (Brahmi script): *"Siri Yana Satakanisa"* (King Yajna Sri Satakarni) 🏆
+---------------------------------------------------------------------------------------------------+

These coins were not mere ornamental tokens, but high-velocity regional currency backing maritime commercial transactions across the Coromandel coast.

⚓ 2. Bi-Coastal Port Networks & The Periplus Account

The Greek navigation guide Periplus of the Erythraean Sea (50–70 CE) highlights Satavahana ports as the primary trading hubs of the Deccan:

🏛️ 3. Buddhist Monastic Guilds (Nigamas) & Port Financing

Maritime commerce and religious patronage were inextricably linked under the Satavahanas:

• Merchant Guilds (Srenis / Nigamas): Wealthy maritime traders (Mahasarthavahas) deposited gold endowments with Buddhist viharas at Kanheri, Karle, Bedse, and Ajanta, which served as ancient banking institutions, insurance underwriters, and secure inland rest-houses along the mountain passes (Ghats) connecting coastal ports to inland markets.
