Guiding Ancient Navigation and Trade in the Maldives
The Indian Ocean has been a hub for maritime trade for thousands of years, connecting East Africa, the Middle East, South Asia, Southeast Asia, and East Asia.
Sailors relied on the stars for navigation, especially during nighttime voyages. Celestial maps helped identify key stars and constellations, such as the North Star (Polaris) or specific southern constellations, to determine direction and latitude.
Monsoon winds, which were predictable and seasonal, facilitated trade, and celestial maps complemented this knowledge by providing navigational aids during long voyages.
The names of nakshatras in other languages are adapted from the Sanskrit variation (apabhramsa) through Pali or Prakrit. The variations evolved for easier pronunciation in popular usage.

Names in Maldivians and Asian languages
The names of nakshatras ( Nakaiy ) in different languages are derived from the Sanskrit variation (apabhramsa) via Pali or Prakrit. These variations developed to facilitate easier pronunciation in everyday use.

Cultural and Intellectual Exchanges:
Indus Valley Civilization (c. 3300–1300 BCE):
While direct evidence of celestial maps from the Indus Valley Civilization is scarce, seals and artifacts suggest an awareness of astronomical phenomena. For example, some seals depict star-like patterns or animals associated with constellations.
The Indus Valley’s advanced urban planning and trade networks imply knowledge of seasonal cycles, possibly linked to celestial observations.
However, their contributions to celestial mapping are speculative, as no written records survive.

Cultural and Religious Significance:
Constellations and celestial events often had mythological or religious significance. In Indian traditions, nakshatras (lunar mansions) were linked to Vedic rituals and astrology.
Arabs and Persians integrated celestial maps into Islamic practices, such as determining prayer times and the direction of Mecca (qibla).
Celestial Maps
The earliest known star chart, dating back to 1534 BC from ancient Egypt, marks the beginning of celestial mapping. These maps were crucial for navigation, especially for sailors and travelers, and for timekeeping to track seasons and agricultural cycles. Additionally, they played a role in astrology, where the positions of stars were believed to influence human affairs, and in understanding the structure of the universe, reflecting humanity's curiosity about the cosmos.
Conclusion
The collection of celestial maps and weather data in the Indian Ocean by the Indus Valley, Greeks, Romans, and Arabs was primarily for trade and navigation, driven by the need to connect distant markets. Astronomy was a cornerstone, with each civilization leveraging celestial observations to enhance maritime capabilities. Ideas were formed through sailors' experiences, cultural exchanges, and astronomical knowledge, with the Arab civilization's detailed records standing out as particularly influential.
