A Menagerie of Monoliths

Today I thought I'd have a closer look at monoliths which have similarties with megaliths.

Wikipedia definies a monolith as:
A monolith is a geological feature such as a mountain, consisting of a single massive stone or rock, or a single piece of rock placed as, or within, a monument. Erosion usually exposes the geological formations, which are most often made of very hard and solid metamorphic rock.


Now lets take a look at the various types of monliths...

Obelisk

An obelisk (Greek obeliskos, diminutive of obelos, "needle") is a tall, thin, four-sided, tapering monument which ends in a pyramidal top. Ancient obelisks were made of a single piece of stone (a monolith). The term stele (plural: stelae) is generally used for other monumental standing inscribed sculpted stones not of classic obelisk form.

Stele

A stele (from Greek: στήλη, stēlē, IPA: [ˈstili]; plural: stelae, στῆλαι, stēlai, IPA: [ˈstilaɪ]; also found: Latinised singular stela and Anglicised plural steles) is a stone or wooden slab, generally taller than it is wide, erected for funerary or commemorative purposes, most usually decorated with the names and titles of the deceased or living—inscribed, carved in relief (bas-relief, sunken-relief, high-relief, etc), or painted onto the slab.

Rune stone

Rune stones are stones with runic inscriptions dating from the early Middle Ages but are found to have been used most prominently during the Viking Age. Compared to western Europe, Scandinavia has poor written evidence for its early medieval history in favor of an oral skaldic tradition.

I think monoliths are a bit more interesting than megaliths...
