Die Mondknoten oder Drachenpunkte sind die Schnittpunkte der Mondbahn mit der Ekliptikebene: der aufsteigende Mondknoten (übliches Symbol: ☊) ist derjenige, bei dem der Mond von der südlichen auf die nördliche Seite der Ekliptik wechselt ("aufsteigt")

Als drakonitischer Monat (drakon / δράκων: Griechisch für Drache) wird die Zeitspanne zwischen zwei aufeinander folgenden Durchgängen des Mondes durch den aufsteigenden Knoten bezeichnet.

Dieselbe etymologische Bedeutung steckt in der „Ekliptik“ (griechisch ékleipsis – wörtlich „Verdeckung, Auslöschung“). Er findet sich auch in der chinesisch-konfuzianischen Mythologie bei Xi und He, 羲和, den himmlischen Beamten für Sonne und Mond. Dieser Mythos steht jedoch in keinem bekannten Zusammenhang mit dem Sternbild „Drache“.

Der drakonitische Monat dient der Berechnung von Finsterniszyklen, den regelmäßigen Wiederholungen von Sonnen- und Mondfinsternissen.

Drachenkopf (Caput draconis, aufsteigender Mondknoten)

Drachenschwanz (Cauda draconis, absteigender Mondknoten)

Vom Bild des Drachen, der bei einer Finsternis die Sonne bzw. den Mond verschluckt, leitet sich der alte Ausdruck Drachenpunkt ab (lateinisch draco „Drache“).

    .

 .

Nur in der Nähe eines Durchgangs des Mondes durch einen der Knoten sind Finsternisse möglich:

eine Mondfinsternis nur bei gleichzeitigem Vollmond

eine Sonnenfinsternis nur bei gleichzeitigem Neumond.

Beide Finsternistypen können sowohl am aufsteigenden als auch am absteigenden Knoten auftreten.

Das Zeitintervall zwischen zwei Durchgängen der Sonne durch denselben Mondknoten bezeichnet man als Finsternisjahr.

A manual produced for emperors to decode the stars, the Astronomicum Caesareum is also an extraordinarily beautiful book

Using the Astronomicum Caesareum Book

Page from Astronomicum Caesareum (May 1540), Michael Ostendorfer

This most sumptuous of all Renaissance instructive manuals explained the use of the astrolabe (for calculating the altitude of stars) and other instruments used for computing planetary positions. The author, court astronomer to Emperor Charles V, also provided new observations on the comet of 1531 (Halley's Comet). Only about forty copies of this work survive; very few still have the seed pearls that were originally attached to the string markers on each of the eighteen disks.

I don’t often think of people from the Renaissance as having instruction manuals, especially for things like astrolabes, but here we are. Plus that is an awesome sky chart; modern astronomy books should take note.

Petrus Apianus (1495 – 1552), also known as Peter Apian, Peter Bennewitz, and Peter Bienewitz, was a German humanist, known for his works in mathematics, astronomy and cartography. His work on cosmography presented in his most famous books Astronomicum Caesareum (1540) and Cosmographicus liber (1524) were extremely influential in his time. Numerous editions in multiple languages were published until 1609.
