Moria – Two meanings
In the fiction of J. R. R. Tolkien, Moria (Sindarin for “Black Chasm”) was the name given by the Eldar to an enormous underground complex in north-western Middle-earth, comprising a vast network of tunnels, chambers, mines and huge halls or ‘mansions’, that ran under and ultimately through the Misty Mountains. There, for many thousands of years, lived the Dwarf clan known as the Longbeards.
According to Tolkien’s fiction, the city and one-time centre of dwarven industry was also called Hadhodrond by the Sindar, Casarrondo by the Noldor and Phurunargian in the Common Speech, all meaning the Dwarrowdelf. For over a thousand years of the Third Age it was widely known as Moria, “Black Chasm” or “Black Pit”, from Sindarin mor=”black” and iâ=”void, abyss, pit”.[1]

In ancient Greece, a moria was an olive tree considered to be the property of the State.
From Attic Orators, vol. I. p. 289:
Throughout Attica, besides the olives which were private property (ἴδιαι ἐλαῖαι, Lys. or. 7 § 10) there were others which, whether on public or on private lands, were considered as the property of the State. They were called moriae (μορίαι)–the legend being that they had been propagated (μεμορημέναι) from the original olive which Athena herself had caused to spring up on the Acropolis. This theory was convenient for their conservation as State property, since, by giving them a sacred character, it placed them directly under the care of the Areiopagus, which caused them to be visited once a month by Inspectors (ἐπιμεληταί, Lys. or. 7 § 29), and once a year by special Commissioners (γνώμονες, ib. § 25). To uproot a moria was an offence punishable by banishment and confiscation of goods (ib. § 41).
