the angel who bears the secret is connected with the meridian of the sun, for the text says that he appeared as 'the sun was crossing the midpoint of its course.' The angel bears the mysterious elixir on his head and, by his relationship to the meridian, makes it clear that he is a kind of solar genius or messenger of the sun who brings 'illumination,' that is, an enhancement and expansion of consciousness.
Jung identifies the Meridian of the Sun in the Isis vision as the locus of a solar messenger whose appearance at solar culmination symbolises an intensification and broadening of consciousness.
the figure following behind the sacrificer is named the 'Meridian of the Sun,' and his head is to be cut off. This striking off of the golden head is also found in the manuscript of Splendor solis as well as in the Rorschach printing of 1598.
Jung establishes the 'Meridian of the Sun' as a named alchemical personification in the Zosimos visions whose decapitation represents the extraction of the arcane substance from the seat of solar consciousness.
in the vision of Isis, the angel who bears the secret is connected with the meridian of the sun, for the text says that he appeared as
This parallel passage confirms the association of the solar meridian with the angelic bearer of the alchemical secret, underscoring the psychic nature of the arcanum disclosed at the sun's midcourse.

the significance of the horizontal and vertical axes of the birth-chart — horizon and meridian. What is below the horizontal axis is made invisible by the Earth... What is above, reaches us through the air. It is the outer, objective realm.
Rudhyar establishes the meridian as one of the two structural axes of the birth-chart, defining the boundary between subjective interiority and objective exteriority as a fundamental cross of incarnation.

Rudhyar is infuriated by the Equal House Method, feeling it over-emphasizes the horizon at the expense of the equally important vertical meridian axis, as if
Sasportas records Rudhyar's insistence that the meridian axis holds equal structural and psychological importance to the horizon, resisting any house system that marginalises it.

every meridian of our planet during that cycle comes, by precession, in conjunction with every degree of the zodiac in turn. (This is the same as saying that the vernal point comes in contact successively with every meridian.)
Rudhyar extends the meridian concept to the planetary scale, treating each terrestrial meridian's precessional contact with the full zodiac as one of three analogically equivalent cycles of complete experience.

The index of Alchemical Studies clusters the Meridian of the Sun with sun, gold, and consciousness references, confirming its systematic status as a key alchemical symbol across multiple pages of Jung's commentary.

meridian, 46 of the Sun, 63, 72, 80ff; see also life, middle
The concordance entry in Alchemical Studies explicitly cross-references the Meridian of the Sun with 'life, middle,' confirming its semantic equation with the midpoint of a life-process or solar arc.

they had developed a correspondence between various types of human activity and the different watches or houses. In this way, the houses became the frame of reference through which the potentialities of a planet and sign combination could be related to the actual events and concerns of life.
Sasportas provides the cosmological background of watches and angles within which the meridian's role as the vertical axis of the chart is historically situated.
