No
The constellations near the plane of the ecliptic (the zodiacal constellations) are only visible at certain times of the year. The constellations towards the poles (N and S) are visible at all times of the year from their respective hemispheres. In the South, the Southern Cross would be one example and in the North the Great Bear (or plough) would be another.
Based on the other constellations I would say no.

Constellations are patterns of stars in the sky, if the constellations disappeared then all the stars would disappear, and there would be virtually no astronomy. :(
The Southern Cross is not an actual object. The constellations are ways of grouping stars in ways that make sense to earth observers. The stars of this constellation may or may not be in reasonable proximity to one another, but in any event, you would have to consider the distances of each individual star. See link for more. Three of the four stars in the Southern Cross are at approximately the same distance. They are the two brightest ones and the faintest one, which are between 600 and 680 light years away. The other one is at about one fifth the distance, 135 light years.
While the Egyptians used many of the same constellations as markers, they used them for determining direction and the time of year, e.g. when the Nile would flood.
The Australian flag or the ski.
The zodiac is the collection of constellations around the meridian that are familiar astrological signs (capricorn, virgo, taurus, aries, leo, etc.) There are many constellations in both the northern and southern hemispheres that are not part of the zodiac. Some that you may have heard of in the northern hemisphere include Orion, the big and little dippers (formerly Ursa Major and Ursa Minor), and Cassiopeia.
There is one zodiac constellation that is not included in the traditional zodiac calendar. That constellation is Ophiuchus, and it lies between Scorpius and Sagittarius. This means there are 13 zodiac constellations. Constellations cannot be "hidden," so to speak. They are a fabrication of the human mind and would not exist elsewhere in the universe as we see them on Earth. Currently, we have 88 constellations (some of which are Northern hemisphere constellations, others of which are Southern hemisphere constellations) and their boundaries (constellations are not just the stars that make up a shape, but every celestial object in a defined region in the sky) fill the entire sky.
you would sell more goods in LOWER (meaning Northern because that's the lower part of the river) Egypt, because that's where the Nile Delta is located, which is a major trade corridor. From the Nile Delta, ships can go by water to the Mediterranean, which can help the merchants get to Southern Europe and the Middle East. The Nile Delta is also close to Egypt's Capital and most populated city, Cairo, which is in the NORTHERN part of the country. Merchants could sell in Cairo, because of all the people there. The Sahara Desert is located in Southern Egypt. Because of this, SOUTHERN Egypt has the lowest population density of the whole nation. The only people that are there are nomadic herders, and merchants who travel by camel. So to answer this question, if you were a merchant in Egypt, you would sell more goods in NORTHERN (or lower) Egypt than in Southern Egypt. North is above, and Southern is below. Look it up
