ANALEMMA is a word from the Greek language.
It is composed of ANA and LEMMA.
This means "taken from above”.
In other words "top view" or "vertical projection”.
The ellipse of an analemmatic sundial is therefore the vertical projection of
an equatorial sundial.

The Armenian sundials are more a building ornament than an instrument to
measure the time.
The sundial scene is divided into 20 or 24 parts at equal angles (ie of 18 or
15 degrees).
The shadow of a gnomon will indicate different time periods depending on the
date.

It alienates us, further than standard time does, from our natural time, solar
