Turquoise tablet

Turquoise⁽¹⁾ tablet

It is true without lying, certain and most true⁽²⁾: each attribute has its own magic tone; and magical tones are the essence of all attributes.⁽³⁾

The magical tones of the lengths are too shallow⁽⁴⁾ for the mortal's ear to perceive, but the magic pipes transpose them by 19 octaves and a major sixth down⁽⁵⁾.

The pipes are 1 gradus (simple step) long and the length of the beak depends on the size of the cross section.⁽⁶⁾.

The soprano pipe (C5, c″) is 12 inches long (300 mm for metric inch), that is one foot.⁽⁷⁾

Hard or sharp mesosoprano pipe (A4, a′) is a minor third longer, ie 14⅖ inches (360 mm for metric inch).

The soft or flat mesosoprano pipe (Ab4, as′) is a major third longer than the soprano pipe, 15 inches (375 mm for metric inch), i.e. one palmipes.

The sub-soprano pipe (G4, g′) is a perfect fourth longer than the soprano pipe, 16 inches (400 mm for metric inch).

The alto pipe is a perfect fifth longer than the soprano, 18 inches (450 mm for metric inch), or one cubit.

The hard or sharp sub-soprano pipe (E4, e′) is a minor sixth longer than the soprano pipe, ie 19⅕ inches (480 mm for metric inch).

The soft or flat sub-soprano pipe (Eb4, es′) is a major third longer than the soprano pipe, 20 inches (500 mm for metric inch).

The tenor pipe (C4, c′) is 24 inches (600 mm for metric inch) long.

Hard or sharp baritone pipe (A3, a) is a minor third longer, ie 28⅘ inches (720 mm for metric inch).

The soft or flat baritone pipe (Ab3, as) is a major third longer than the tenor pipe, ie 30 inches (750 mm for metric inch).

The sub-tenor pipe (G3, g) is a perfect fourth longer than the tenor pipe, ie 32 inches (800 mm for metric inch).

The bass flute is a perfect fifth longer than the tenor pipe, 18 inches (900 mm for metric inch), or one yard.

Hard or sharp baritone pipe (E3, e) is a minor sixth longer than the tenor pipe, ie 38⅖ inches (960 mm for metric inch).

The soft or flat baritone pipe (Eb3, es) is a major third longer than the tenor pipe, ie 40 inches (1000 mm for metric inch).

The sub-bass pipe (C3, c) is 48 inches long (1200 mm for metric inch).

Closed pipes and human voices sound an octave deeper than open pipes of the same name.

Translator's comments

In the area of the turquoise quarries in Sinai, the Egyptian goddess Hathor was worshiped and also called the "lady of turquoise". Semitic texts mention her as Baģhlat, which means "Lady."
Hermes Trismegistos used a similar introduction in his Emerald Tablet.
This formulation appears in a strongly altered form at some philosophers: A phenomenon is a way of existence of the substance, substance is the existence of a phenomenon.
Instead of high and low tones we speak of shallow and deep tones, because these terms better describe their wavelength.
The speed of light is 299,792,458 m / s (exactly), turquoise plate therefore sets the standard speed of sound at 343.085240936279296875 m / s (exactly).
The antinodes are not located exactly at the mouth of the pipe and at its open end, but somewhat outside. In the case of a cylindrical pipe, the hole correction is about 0.3 of the diameter, correction for the mouth about 1.36 of the diameter, the total correction is therefore 5/3 of the diameter; for rectangular pipes, the total correction is twice the depth (width does not matter).
In modern tuning standard based on A4 with a frequency of 440 Hz, C5 has a frequency of 528 Hz. A foot of approximately 324.9 mm would correspond to this. For the 308.7 mm Hexapotamian foot, C5 has a frequency of approximately 555.111 Hz, which is almost a semitone higher. For the 298.08 mm Optaquan foot, the C5 has an even higher frequency, approximately 575.5 Hz. A foot of approximately 335 mm would correspond to a physical tuning with a 512 Hz C5.

Emerald Tablet

Tis true without lying, certain and most true.
That which is below is like that which is above.
And that which is above is like that which is below to do the miracle of one only thing
And as all things have been and arose from one by the mediation of one: so all things have their birth from this one thing by adaptation.
The Sun is its father, the moon its mother, the wind hath carried it in its belly, the earth is its nurse.
The father of all perfection in the whole world is here.
Its force or power is entire if it be converted into earth.
Separate thou the earth from the fire, the subtle from the gross sweetly with great industry.
It ascends from the earth to the heaven and again it descends to the earth and receives the force of things superior and inferior.
By this means you shall have the glory of the whole world and thereby all obscurity shall fly from you.
Its force is above all force, for it vanquishes every subtle thing and penetrates every solid thing.
So was the world created.
From this are and do come admirable adaptations where of the means is here in this.
Hence I am called Hermes Trismegist, having the three parts of the philosophy of the whole world.
That which I have said of the operation of the Sun is accomplished and ended.
