A  long coastline gave Gujarat opportunities to establish cultural  linkages internationally. Indians in the port cities were engaged in  manufacturing vessels, studying stars and winds, erecting light  houses and building ports at a time when many countries were living  in darkness. Merchant ships ferried not only traders but also kings,  monks and teachers disseminating ideas and ideals, technology and  spirituality, arts and culture. Thus marine trade not only brought  effulgence to the country but also became instrumental in spreading  Indian culture beyond its boundaries.
THE  EARLIEST KNOWN PORT OF THE WORLD
Gujarat  ruled the world of navigators.  One of its coastal cities- Lothal is  the earliest known port of the world equipped with berth and service  ships.  Its history goes back to 3000 BC as one of the cities of the  ancient Indus valley civilization. Sophisticated technique and tools  for cutting gems, making beads and metallurgy were pioneered in  Lothal. It reigned the oceanic waves up to 11th  century AC. Modern oceanographers accept that Harappans possessed  great knowledge relating to tides, hydrography and maritime  engineering to build a dock on ever changing course of the Sabarmati.
VOYAGES  TO INDONESIA 
Merchants  of Gujarat must have traveled to Indonesia in large numbers and for  long durations of time as there is a saying to this day that one who  goes to Java never returns. It is a tiny chunk of memories from past  but important to trace the history of travels abroad. It says that  one who goes to Java never comes back but who returns brings so much  affluence that it lasts from generation to generation:
जे  जाए जावे तो कदी न पाछो आवे/
जो  आवे तो पर्यानापर्या चावे  एतलू लावे//
Regular  sailing from India to Indonesia gave way to Indian kings going to the  islands. Javanese chronicle state that in about 603 AC a king of  Gujarat sailed for Java with his son,  five thousand cultivators,  artisans, warriors, physicians and scholars in six large ships and a  hundred small vessels. These were the people who laid foundation of  the culture of Indonesia and built sanctuaries dedicated to Lord  Shiva like Prambanan and the sacred Buddhist monument of world fame-  Borobudur.  There is another temple- Chandi Plaosan from where an  inscription from 8th  century talks about Gujaratis who had built that- satata-gurjara-desa-samagataih. 
SOMNATH  TO THE ISLAND COUNTRIES IN SEA
Somanath  temple, the glory of Bharata, is dedicated to Bhagavan Shiva as the  Lord of Moon. Its waxing and waning has fatal effects on the waves of  the oceans tossing the ships in deadly turbulence. Lord Shiva  controlled the turbulence of the ocean by holding the Moon in his jata-mukuta as he did to handle the flow of river Ganga by receiving it first in  his jatas. He  became the guardian of transoceanic merchants. Lord Shiva was taken  to Indonesia as their supreme deity. Since eighth century Shiva has  been alluded to in inscriptions, texts, temples and literature. The  earliest Shaiva inscription is from 732 AC when almighty monarch King  Sanjaya established a Shiva-linga. Shaiva temple Prambanan relates  the crowning glory of Indonesian.  The most important text on Shaiva  philosophy written in Sanskrit followed by commentary in Old  Javanese, is Bhuavankosha. The legend of burning of Kama with the  cosmic fire emanating from his third eye is one of the gems of  Javanese literature. 
Ocean  goers were described as dvipantara  gamaniyah,  meaning ‘those who go to Indonesia’. Poet Tagore wrote that  Nataraja Shiva, the ‘King of Dance’ came to Indonesia and was  gratified with the worship of the people the boon that he gave to  them was his dance. 
The  colossal statue of Shiva at Elephanta caves, a small island of  Gharapuri, captured by the Portuguese from the King of Gujarat must  have blessed the navigators over the centuries. The coastline of  Champa (in modern Vietnam) is decked with shrines dedicated to Lord  Shiva who endowed the merchants with life, like Somnath. 
SRILANKA
Srilanka  was in close connection with Gujarat. The Sinhalese language has a  long history going back to the days of Ashoka and falls in line with  north Indian languages- Gujarati, Marathi, Bengali and others in the  matter of words derived from Sanskrit which permeates in every walk  of life. 
The  Buddhist text Mahavansha states that the king of Srilanka Vijaya  sailed from Suparaka to Srilanka. Fragments of the 8th  rock edict of Emperor Ashoka found from Sopara in Maharashtra, a city  close to modern Gujarat, emphasize the beneficial nature of the  Dharma-yatras replacing vihara-yatras meaning pleasure trips. A stupa  at Sopara enshrined fragments of the begging bowl of the Buddha.
FROM  GUJARAT TO MALAYSIA
The  Pancha-danda-chhatra-prabandha from Vikrama-vanshavali refers to  voyages from Shuparaka to Kedah in Malaysia. The  Katha-sarit-sagara relates the shipwreck of Princess Gunavati on the  coast of Suvarnadvipa on her way from Kataha (Kedah in Malaysia) to  India. Indian sailors were visiting the shores of SE Asia in very  remote times and Indonesian traders, seafarers par  excellence,  frequented Indian coasts.
SHIP BUILDING
Kutch  has preserved 200-250 years old log books of mariners. There a family  has the name Wadia which comes from Sanskrit vardhaki meaning ‘a ship builder’. The Wadia family of Surat that became  famous for ship building has even its logo as a ship honoring their  family legacy. The  national anthem of the United States was written in 1812 on a Wadia  built British Navy ship, the HMS Minden.
Suparaka  was the dwelling place of Parashuram, a major commercial and an  important port town from 3rd  to 9th  century. References to it can be traced in Hindu, Buddhist and Jaina  sources. The 4th  century Sanskrit text of the Jatakamala of Aryashura recounts the  voyages of seasoned steersman Suparaga  and sums up the navigational knowhow of this famous pilot who knew  the courses of the stars and could always readily orient himself. He  also had a good knowledge of the signs of good and bad weather. He  distinguished the regions of the ocean by the fish, by the color of  the water, by the birds, the mountains, and other indications. 
CANALS  AND WATER RESERVOIRES 
With  the spread of Indian culture beyond its boundaries Indians built  canal systems. Dholavira in Kutch, the grandest of its time of the  five Harappan sites is known for a unique feature that is  sophisticated water conservation system of channels and reservoirs,  the earliest found anywhere in the world. This speaks  eloquently about their advanced hydraulic engineering, given the  state of technology in the third millennium BCE.  A coastal route must have linked it to Lothal.
BABYLONIA
The  Buddhist story Baberu  Jataka narrates Indian merchants, having taken voyages to the land of  Babylon (Balylonis). The western coats had seen great commercial  activities developing contacts with the Arabs who gradually became a  link between India and Europe. The exports included birds, especially  peacocks, beasts, horses, ivory, cotton goods, spices, cereals and  jewelry. 
PERSIA/  IRAN
India’s  connections with Persia are well known. Frescos at Ajanta depict  Persian ambassador being brought to the court of  Pulakesin II, just before 628 AC. Thirteen  centuries have rolled down when the Persians who could not bear the  brunt of Islam fled from their mighty empire and settled in Sanjan in  Gujarat. They were allowed to prosper peacefully. They built the  first fire temple in AD 721 to install the holy fire called the  Iranshah, the King of Iran. They have saved their religion and  customs after being driven out of their own motherland, setting an  example that protecting identity is more important than living in the  land of their fore-fathers. Today Zoroastrianism enjoys every freedom  in India. 
DISSEMINATION  OF CULTURE VIA MARINE ROUTES 
Dissemination  of culture via marine routes has been acknowledged by paintings of  large sailing boats at Dun-huang caves in China and Borobudur in  Indonesia when ferry-boats carried Buddhist images, relics and wisdom  texts. The world-famous Ajanta caves too furnish paintings of a  sea-going vessel with high stem and stern, with three oblong sails  attached to as many upright masts. Bhoja has summed up available  information on ship-building in his Yukti-kalpataru which is a sort  of treatise on this art. Indian shipping ever continued to develop  and as late as 1799 AC. F. Baltazar Solvyns speaks of it in  admiration: In ancient times the Indians excelled in the art of  constructing vessels, and the present Hindus can in this respect  still offer models to Europe so much so that the English, attentive  to everything that relates to naval architecture, have borrowed from  the Hindus many improvements which they have adopted with success to  their own shipping.
