These are some of the amazing facts from Valmiki Ramayana in random order:
Dhundu a rakshas mentioned in Ramayana was a volcano
In ancient days 'Patala' was a name given to parts of South-america since it was cut off from the real world, also it has a time difference of about 12 hrs from the Asian countries; navigation was not possible easily nor was air travel possible hence it was virtually cut off from real civilized world. It was abode of Asuras.
In Kishkindha kaand Valmiki, through Sugriv mentions of a trident which is described as: trishiraaH kaa.ncanaH ketuH taalaH tasya mahaatmanaH | sthaapitaH parvatasya agre viraajati sa vedikaH || 4-40-53
A golden pylon resembling a palm tree with three branches as its heads is established on the peak of that mountain as the insignia of that great-souled Ananta, and it will be lustrous with a golden podium.
Also mentioned are the places like Yava dwipa- Java Island, Suvarna dwipa- Sumatra, Antartica- as the land of yama; Vanaras were sent to every part of the world in search of Sita.
Pragjyotishpur-todays Assam and beyond (parts of China) where Narakasura reigned (he was later killed by Krishna)
Hanuman 'LEAPT' the sea and not fly as shown in TV serials; he had the ability to leap great distances also he used to run with great speed.
The Vanaras (men and women) had a custom of marrying more than one spouse (as evident in Vali-Sugriv-tara episode)
River Ganga is 'man-made' ( posted in earlier article )
Bay of Bengal was a land once and it was dug up by 60,000 sons of Sagar hence the name 'Saagar' for the sea; The southern part of India is tapered because of such digging; King Sagar was a great philantrophist
The Videha kings (Janaka) were also Ikshvakus ,they were direct descendent of Vikukshi but since only the first son is entitled with the family name they weren't refered as Ikshvaku; other prominent Ikshvakus were Andhra Ikshvaku and Vishala (today's Vaishali provence) Ikshvaku
