Loch Ness Monster

The Loch Ness Monster is a cryptid, reputedly a large unknown animal that is said to inhabit Loch Ness in the Scottish Highlands. It is similar to other supposed lake monsters in Scotland and elsewhere, though its description varies from one account to the next. Popular interest and belief in the animal's existence has varied since it was first brought to the world's attention in 1933. Evidence of its existence is anecdotal, with minimal and much-disputed photographic material and sonar readings.

The most common speculation among believers is that the creature represents a line of long-surviving plesiosaurs. The scientific community regards the Loch Ness Monster as a modern-day myth, and explains sightings as including misidentifications of more mundane objects, outrighthoaxes, and wishful thinking. Despite this, it remains one of the most famous examples of cryptozoology. The legendary monster has been affectionately referred to by the nickname Nessie (Scottish Gaelic: Niseag) since the 1950s.

Nemesis

In Greek mythology, Nemesis (Greek, Νέμεσις), also called Rhamnousia/Rhamnusia ("the goddess of Rhamnous") at her sanctuary at Rhamnous, north ofMarathon, was the spirit of divine retribution against those who succumb to hubris (arrogance before the gods). Another name was Adrasteia, meaning "the inescapable." The Greeks personified vengeful fate as a remorseless goddess: the goddess of revenge. The name Nemesis is related to the Greek word νέμειν [némein], meaning "to give what is due".

Neptune

Neptune (Latin: Neptūnus) was the Roman god of freshwater and the sea in Roman religion. He is the counterpart of the Greek god Poseidon. In the Greek-influenced tradition, Neptune was the brother of Jupiter and Pluto, each of them presiding over the realms of Heaven, our earthly world and the Underworld, respectively.

Depictions of Neptune in Roman mosaics, especially those of North Africa, are influenced by Hellenistic conventions. Neptune was likely associated with fresh water springs before the sea. Like Poseidon, Neptune was worshipped by the Romans also as a god of horses, under the name Neptunus Equester, a patron of horse-racing.
