μπουρού - शंख ( Shankh)
“Shankham” comes from the two Sanskrit words “Shum” which means something good and the “Kham” meaning water. Hence the meaning of “Shankam” is “The conch holding the sacred water”.
According to the Vedic scriptures, the Shankha (η μπουρού) is one of the most auspicious objects that emerged from the sea during the churning of the sea( Ksheera Sagara samudra manthan). Hence it is regarded as the brother of Goddess Lakshmi, the ruler of wealth. Most of the Gods and Goddesses hold the Shankha in their hands. Shankh is one auspicious nine objects – Navanidhi – of Kubera who is the Lord of wealth. Blowing the Shankha is regarded as an auspicious sound at the start or end of any ceremony.
According to a legend of Harivamsa Purana, Krishna killed the whale-demon called Pancha-jana in the seas, and the Shankhas were formed out of the bones of this demon (’pancha-jane daitya-visishe bhavah pancha-janyah’;‘pancha-jano nama daityah samudre timira-rupa asit; tad asthi-jatam’). Sometimes, the name Pnacha-janya is given to a rare and freak formation of a conch-shell in which the cavity contains within it another smaller conch-shell attached to it. A specimen preserved in the Chamundesvari temple atop the hill in Mysore contains still another (third) conch-shell.
The use of the Shankha to announce the commencement of an encounter on the battlefield has been mentioned in the great epic Mahabharata. In Bhagavad-gita, we read that Krisna’s conch-shell was named ‘Panchajanya’,
Arjuna’s ‘Devadatta’,

Το κοχύλι το κατασκευάζουν
ζώα που λέγονται Μαλάκια, για να να προστατέψουν το μαλακό σώμα τους.
O Αριστοτέλης,
πρωτοπόρος ζωολόγος, φιλόσοφος και φυσιοδίφης,
στην "περί ζώων
ιστορία" περιγράφει με εξαιρετική λεπτομέρεια
το διαχωρισμό των μαλακίων
σε "μαλακόστρακα" και "οστρακόδερμα".
Σύμφωνα με την ελληνική
μυθολογία, η Αφροδίτη, η θεά του έρωτα
και της ομορφιάς,
αναδύθηκε από τη θάλασσα μέσα από ένα κτένι
κοντά στις ακτές της
Κύπρου.
“Πέτρα του Ρωμιού" ("The rock of the Greek"),
Aphrodite's legendary birthplace in Paphos ,Cyprus
and is depicted in popular art
standing on floating object — in this case, on a lotus blossom. She appeared
after the gods churned the cosmic ocean for 100 years using the snake Vasuki to
turn Mount Mandara
