Seven of the constellations found along the ecliptic represent animals, as they did in Greek and Roman times: Aries (the Ram), Taurus (the Bull), Cancer (the Crab), Leo (the Lion), Scorpius (the Scorpion), Capricornus (the Goat), and Pisces (the Fish). The constellations represent the. The above image is the established symbol (also called glyph) for the Zodiac sign Scorpio, the Scorpion. It’s an M with the scorpion tail stinger. Both the Zodiac sign and its symbol have been along for ages. The Zodiac division of the ecliptic into twelve parts. Scorpio Symbolism + Myth The constellation known as Scorpio goes back to Babylonian times, where it was called “the creature with the burning sting.” Scorpio contains the red star Antares, which means “the rival of Mars,” and is also called “the heart of the Scorpion.”.
Constellation Crux [Stellarium]
Constellation Crux the Southern Cross, is a southern constellation laying south of conetalltion Centaurus. Crux spans only 13 degrees of the zodiac in the sign of Scorpio, and contains 5 named fixed stars. The constellation is represented on the flag of Brazil.

Crux is said to give perseverance, but many burdens, trials and responsibilities, together with much suffering and many hardships. In connection with rulerships of countries it may be noted that Brazil was named the Land of the Holy Cross by the discoverer Cabral on May 1st 1500, and that the constellation Crux has been represented on the postage stamps of that country. 
In the new identification of ‘the Cross’, the theme of sacrifice and stoic resilience has been further emphasized with heightened ecclesiastical connections…a need to sacrifice the animal/ego-driven instincts in pursuit of fortitude in the face of adversity, spiritual advancement and wounds that can never be healed. 
With us it is the Southern Cross. It was unknown to the ancients by its present title, its four chief stars being noted by Ptolemy as a part of the Centaur (Centaurus), which now surrounds it on three sides… Crux lies in the Milky Way, — here a brilliant but narrow stream three or four degrees wide, — and is noticeable from its compression as well as its form, being only 6° in extent from north to south, and less in width, the upper star a clear orange in color, and the rest white; the general effect being that of a badly made kite rather than of a cross. So that, notwithstanding all the poetry and romance associated with it, — perhaps owing to these, — it usually disappoints those from northern latitudes who see it for the first time. 
The Hebrew name was Adom, which means cutting off, as in Daniel 9:26 “After threescore and two weeks shall Messiah be cut off.” The last letter of the Hebrew alphabet was called Tau, which was anciently made in the form of a cross. This letter is called Tau, and means a mark; especially a boundary mark, a limit or finish. And it is the last letter, which finishes the Hebrew alphabet to this day.
The Southern Cross was just visible in the latitude of Jerusalem at the time of the first coming of our Lord to die. Since then, through the gradual recession of the Polar Star, it has not been seen in northern latitudes. It gradually disappeared and became invisible at Jerusalem when the Real Sacrifice was offered there; and tradition, which preserved its memory, assured travellers that if they could go far enough south it would be again seen. Dante sang of “the four stars never beheld but by the early race of men.” It was not until the sixteenth century had dawned that missionaries and voyagers, doubling the Cape for the first time, and visiting the tropics and southern seas, brought back the news of “a wonderful cross more glorious than all the constellations of the heavens.”
It is a small asterism, containing only about five stars, viz., one of the 1st magnitude, two of the 2nd, one of the 3rd, and one of the 4th. Four of these are in the form of a cross.
Long before the Christian Era this sign of the Cross had lost its true meaning, and had been perverted in Babylon and Egypt as it has since been desecrated by Rome. The Persians and Egyptians worshiped it. The cakes made and eaten in honor of the Queen of Heaven were marked with it. This heathen custom Rome has adopted and adapted in her Good Friday cakes, which are thus stamped. But all are alike ignorant of what it means, viz., “IT IS FINISHED.”
In Egypt, and in the earliest times, it was the sign and symbol of life. Today, Romanists use it as the symbol of death! But it means life! Natural life given up, and eternal life procured. Atonement, finished, perfect, and complete; never to be repeated, or added to. All who partake of its benefits in Christ now, in grace, by faith “ARE made nigh by the blood of Christ” (Eph 2:13), and of them Jesus says, “He that heareth my voice, and believeth on Him that sent me HATH everlasting life, and shall not come into judgment; but IS PASSED from death unto life” (John 5:24). So perfect and complete is the work which Jesus finished on the Cross that we cannot seek to add even our repentance, faith, tears, or prayers, without practically asserting that the work of Christ is not finished, and is not sufficient!
The Hebrew names of this constellation–Adom and Tau–rebuke our Pharisaic spirit, which is the relic and essence of all false religions, and points to the blessed fact that the Sacrifice was offered “once for all,” and the atoning work of Redemption completely finished on Calvary.
In the ancient Egyptian Zodiac of Denderah this first Decan of LIBRA is represented as a lion with his tongue hanging out of his mouth, as if in thirst, and a female figure holding a cup out to him. Under his fore feet is the hieroglyphic symbol of running water.
