'Phasis' (-h pl. -ai Phaseis) comes from the verb 'phaino' (I , according to the Orthodox Church tradition, read it as 'phaeno') which means (in its passive form 'phainomai) 'to appear', 'to be seen' .
So 'Phasis' means simpy 'Appearance'.
In Greek-language Astrology, 'Phasis' means what today is known as Heliacal Appearance.
[[[
From the same verb comes also the english word 'phenomenon'.
In Greek it is written as 'phainomenon -to'
(pronounced in the Orthodox Greek tradition the same way as is pronounced the English word !)
'Phainomenon -to' means 'something that is appearing', 'something that is seen' (present passive participle)

The heliacal appearances of the planets carried a lot of weight in the Hellenistic Astrology and was a paramount factor to the Babylonians.
I noticed that the researchers into the Hellenistic Astrology became aware of the import of the heliacal phases.
I would like, however, to turn their attention now to one very important question.
The meaning of a planet being 'under the beams' ( ''Yp-augos ) was a practical reality for the Babylonians and was still clear to the Greeks- either as a conception or a fact of reality.
Even some of the Arabs, like Abenragel e.g., clearly stated what this meant.
To be 'under the beams (of the Sun)' meant 'to be invisible to the naked eye'.
This was also known to Alchabitius and to his european commentator John of Saxonia.
The Babylonians could compute the heliacal phases of the planets based on their records of previous appearances and knowledge of the heliacal cycles of the planets id est after how many years do a certain heliacal appearance repeat again.
From the Greeks, Ptolemy tried to compute the phases with a very simple and very inexact algorithm (of arcus visionis) described in the last chapter of the Almagest. The Arabs made their 'zij' tables of visibilities of the planets employing this for 1,000 years !
It gives very inexact results.
The Greek astrologers simplified things further, accepting some limit of nearness to the Sun when they find a planet to be 'under the beams'. They measured this on the ecliptic of course.
Dorotheus put different 'orbs of being under the beams' for different planets.
For Mars he gave 18 degrees and for Mercury 19.
Porphyry said that for a planet to have (any) power its distance from the Sun should be more than 15 degrees...
Doing this though, the Greeks were well aware that this was a rough estimate.
They (Valens, Porphyry, Rhetorius) explicitly talked about the heliacal phases and named them with their proper terms.
'Phasis anatolh -h' was used to denote heliacal rising and 'phasis dytikh -h' for heliacal setting.
The Arabs moved further away from the real sky above Babylonia and Greece.
They seemed, if not to have forgotten the phases, at least to pass them in silence.
But they still talked a lot about a planet being 'under the beams'.
Abenragel gave different orbs not only to the different planets but also as dependent on whether the planet was emerging from the Sun (heliacally rising) in the morning or was disappearing into the Sun ( heliacally setting) in the evening.
For Mars he gave the values of 9 (rising) and 15 (setting) degrees distance from the Sun on the ecliptic and for Mercury he gave 7 degrees both ways.
In later times Argolus gave 17 degrees to all planets as an orb for being under the beams of the Sun and that's it.
Then, just few decades ago, most astrologers have not even heard about this!
Now we have a case.
Here in a most amazing way we can trace how a real omen-experience in Sumero-Babylonia went through Greece, the Arabs, the Medieval Europe and landed in contemporary Horary Astrology almost totaly disappearing from the Natal.
In the way, though, this 'thing' lost a lot of 'real weight'.
From observed reality it became a concept and its real meaning was almost lost in the way and stayed so for few centuries.
In order to put in practice though this 'lost teaching' of most ancient Astro-Sophy we will need to know the exact days of real and observable heliacal appearances of the planets.
Just as they did it in Babylonia and probably some practicing observer-astrologers in ancient Greece.
Whether a planet was visible or not on the birth-day of someone (or something) was, is and will be maybe the most important thing to know about that planet.
Greek authors (Valens) dethroned the ikodespotis (oikodespoths)[=arab Alchocoden] if they found him invisible in this way leaving the nativity an-ikodespotic (genesis anoikodespothtos). Such cases surely were of serious concern.
But how do we compute the real and observable heliacal phases of the planets ?
Well, I have spent more than several years trying to find dependable algorithm and I could not.
The algorithms out there are theoretical [Schaefer, Inklaar] or based on a limited number of babylonian observations 2500 years old (!) [Schoch].
Is this not amazing?!
The modern science and modern Astronomy who take so much pride in themselves and their 'cosmic' age, cannot compute the first day when Jupiter or Mars will appear on the dawn sky!
Well, they cannot compute even the second.
The methods they use [Schoch tables] may give for Mars a tremendous error of several days to several months!
There are no observations of heliacal appearances published in the last 2,000 years and no-one from the institution or lay astronomers observe heliacal events...
This 'horrible' story (for the official modern science) though, deserves a happy-end.
Soon I hope to publish all my own 300 observations that span 10 years and two continents and include them as basis for phases-computation in a computer program.
