Gurmar

Gurmar

Researchers have discovered anti-diabetic medicinal herb Gurmar on Gaya’s Brahmayoni Hill.

About Gurmar:

  • Scientific Name: Gymnema sylvestre
  • It  is a tropical plant that is indigenous to India and grows in the tropical areas of Africa, Australia, and China.
  • Properties:
    • Gymnema sylvestre is a medicinal plant. It is a slow-growing, perennial, woody climber. 
    • In the Ayurvedic system, it is referred to as “Meshasringa” or “Gurmar” and has indications for use in glucose balance. 
    • Gymnemic acid—an active component isolated from leaves of G. sylvestre—has antiobesity and antidiabetic properties; it causes decrease in body weight and inhibits glucose absorption 
    • Gymnema contains substances that decrease the absorption of sugar from the intestine. Gymnema may also increase the amount of insulin in the body and increase the growth of cells in the pancreas, which is the place in the body where insulin is made.

Monitor Lizard

Lunisolar Calendar

Lunisolar Calendar

A researcher at the University of Edinburgh has discovered what he believes to be the earliest lunisolar calendar at Göbekli Tepe, an ancient site in southern Turkey that was once a complex of temple-like enclosures

Key Findings:

  • Göbekli Tepe: often referred to as the world’s first temple, features a series of large stone pillars adorned with ornate carvings. 
    • These carvings have long puzzled researchers, but recent studies suggest they represent an ancient timekeeping system
  • Counting of Days: The carvings on the pillars include a series of V-shaped symbols, each representing a single day. 
    • By counting these symbols, researchers identified a calendar of 365 days, divided into 12 lunar months with an additional 11 days. 
    • This system aligns closely with the modern solar calendar, indicating a sophisticated understanding of astronomy by the ancient people who created it.
  • Depiction of the summer solstice: A V-shaped symbol worn around the neck of a bird-like figure is believed to represent this significant astronomical event
    • This suggests that the ancient inhabitants of Göbekli Tepe were keen observers of the sky, using their calendar to track the changing seasons and celestial events
    • The carvings also include representations of both the sun and the moon, indicating a combined solar and lunar calendar.
  • Historical Significance: Göbekli Tepe’s calendar is not only remarkable for its age but also for its potential historical significance. 
    • Researchers believe that the calendar may have been created to commemorate a catastrophic comet strike that occurred around 10,850
  • About Göbekli Tepe: It is a marvel of ancient engineering and artistry.
    • Built by hunter-gatherers between 9,600 and 8,200 BCE, it predates Stonehenge by more than 6,000 years. 
    • The large stone pillars, some of which weigh up to 20 tons, are arranged in circular enclosures and decorated with carvings of animals and abstract symbols. 
    • The exact purpose of Göbekli Tepe has long been debated, but many believe it was used for ritualistic or ceremonial

Kerala’s Jewish Communities

Recently, Queenie Hallegua, 89, died . She was the last woman of Kerala’s once-vibrant Paradesi Jewish community.

About Malabar Jews:

  • They, also known as the Cochin Jews, trace their history to the days of King Solomon (hypothesised to be in the 10th century BCE, almost 3,000 years ago). 
    • Initially, they settled in Cranganore (present-day Kodungallur in Thrissur district), which the community itself referred to as Shingly.
  •  economic and ceremonial privileges: The oldest documentary evidence of this community — a set of copper plates given to the local Jewish leader by the Cranganore’s Hindu ruler, from circa 1,000 CE — lists various economic and ceremonial privileges that the Jews enjoyed in the region
  • Arrival Of Portuguese: From the 14th century onward, and especially following the arrival of the Portuguese in the 16th century, Malabar Jews moved further south from Cranganore to Cochin (now Kochi) where the local king rolled out the red carpet for them.

About Paradesi Jews:

  • It means“foreign” Jews, who arrived in India in the 15th and 16th centuries from the Iberian Peninsula due to persecution by Catholic rulers. 
  • They fled to India due to persecution by the Catholic rulers of Spain and Portugal, and settled on the Malabar coast alongside pre-settled Jewish communities, as well as in Madras
  • Paradesi Jews adopted the Malayalam language and local customs, but eventually distanced themselves from the older Jewish community in Kerala, leading to the formation of two distinct groups.
  • Western writers, refer to the Paradesis as “White Jews” and the Malabaris as “Black Jews”

Migration back to Israel

  • Welcoming India: Unlike Jewish communities in Europe or West Asia, the ones in India seldom faced anti-Semitism or persecution. Many, like the Koders, rose to high positions as agents of foreign trade, and advisers to Dutch and Hindu rulers. 
  • Migration: Since the 1950s, there has been a steady migration of Kerala Jews to Israel
    • According to estimates, there are well over 4,000 ‘Cochinim’ in Israel today.
