Globus cruciger

Globus cruciger is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Globus cruciger rather than just read about it. In short: The globus cruciger (Latin for 'cross-bearing orb'), also known as "the orb and cross" or stavroforos sphaira (Greek: σταυροφόρος σφαίρα), is an orb surmounted by a cross. It has been a Christian symbol of authority since the Middle Ages, used on coins, in iconography, and with a sceptre as royal regalia.

Key takeaways

  • Globus cruciger belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Globus cruciger to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Globus cruciger from memory before moving on to harder problems.

Reference excerpt

The globus cruciger (Latin for 'cross-bearing orb'), also known as "the orb and cross" or stavroforos sphaira (Greek: σταυροφόρος σφαίρα), is an orb surmounted by a cross. It has been a Christian symbol of authority since the Middle Ages, used on coins, in iconography, and with a sceptre as royal regalia. The cross laid over the globus represents Christ's dominion over the world, literally held in the hand of a worthy earthly ruler. In the iconography of Western art, when Christ himself holds the globe, he is called Salvator Mundi (Latin for 'Saviour of the World'). For instance, the 16th-century Infant Jesus of Prague statue holds a globus cruciger in this manner.

History

Holding the world in one's hand, or, more ominously, under one's foot, has been a symbol since antiquity. To citizens of the Roman Empire, the plain spherical globe held by the god Jupiter represented the world or the universe, as the dominion held by the Emperor. A 2nd-century coin from the reign of Emperor Hadrian shows the Roman goddess Salus with her foot upon a globus, and a 4th-century coin from the reign of Emperor Constantine I shows him with a globus in hand. The orbis terrarum was central to the iconography of the Tetrarchy, in which it represented the Tetrarchs' restoration of security to the Roman world. Constantine I claimed to have had a vision of symbol of Christ above the sun, with the words "In this sign, you shall conquer" (Latin: "In hoc signo vinces"), before the Battle of Milvian Bridge in AD 312. This symbol is usually assumed to be the "Chi-Rho (XP)" symbol, but some think it was a cross. Consequently, his soldiers painted this symbol on their shields and then defeated their foe, Maxentius. With the growth of Christianity in the 5th century, the orb (in Latin works orbis terrarum, the 'world of the lands', whence "orb" derives) was surmounted with a cross, hence globus cruciger, symbolizing the Christian God's dominion of the world. The Emperor held the world in his hand to show that he ruled it on behalf of God. To non-Christians already familiar with the pagan globe, the surmounting of a cross indicated the victory of Christianity over the world. In medieval iconography, the size of an object relative to those of nearby objects indicated its relative importance; therefore the orb was small and the one who held it was large to emphasize the nature of their relationship. Although the globe symbolized the whole Earth, many Christian rulers, some of them not even sovereign, who reigned over small territories of the Earth, used it symbolically. One of the first known depictions in art of the symbol was in the late 4th century AD, possibly as early as AD 388, namely on the reverse side of the gold tremissii of Emperor Theodosius I. The globus cruciger was associated with powerful rulers and angels; it adorned portrayals of both emperors and kings, and also archangels. It remained popular throughout the Middle Ages in coinage, iconography, and royal regalia. For example, it was often used by Byzantine emperors in order to symbolize their authority and sovereignty over the Christian world, usually being done via coinage. The symbol was meant to demonstrate that the emperor ruled both politically and divinely. The papacy, which in the Middle Ages rivaled the Holy Roman Emperor in temporal power, also used the symbol on top of the Papal tiara, which consisted of a triple crown; the Pope did not use a separate orb as a symbol. The globus cruciger (made up of a monde and cross) was generally featured as the finial of European royal crowns, whether on physical crowns or merely in royal heraldry, for example, in Denmark, the Holy Roman Empire, Hungary, Italy, The Netherlands, Portugal, Romania, Spain, Sweden, and Yugoslavia. It is still depicted not only in the arms of European polities for which a monarchy survives, yet also, since the end of communism in 1991, in the arms of some eastern European polities, despite the termination of their historical monarchies. Even in the modern era in the United Kingdom, the Sovereign's Orb symbolizes both the state and Church of England under the protection and domain of the monarchy. The globus cruciger is also routinely featured atop the domes of churches, from Saint Peter's in Rome, to Saint Paul's in London, and many others. A crossless globe is often featured in the portraits of Mughal emperor Jahangir where it both signifies the meaning of his name ("world seizer") and symbolizes his sovereignty. In several contemporary portraits he is often shown standing atop a large cartographic globe or seated on a throne with his feet on a globe.

Use as an alchemical symbol The globus cruciger was used as the alchemical symbol (♁) for antimony. It was also used as an alchemical symbol for lupus metallorum "the grey wolf", supposedly used to purify alloyed metals into pure gold. Lupus metallorum (stibnite) was used to purify gold, as the sulphur in the antimony sulphide bonds to the metals alloyed with the gold, and these form a slag which can be removed. The gold remains dissolved in the metallic antimony which can be boiled off to leave the purified gold.

Worked examples

Example 1 — a first encounter with Globus cruciger

Start with the simplest possible case. Write down what Globus cruciger claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Globus cruciger before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Globus cruciger ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Globus cruciger

In research
Globus cruciger appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Globus cruciger in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Globus cruciger is common in secondary-school and first-year university syllabi. It links to neighbouring topics Byzantine regalia, Christian iconography, Christian symbols, so understanding it makes those chapters shorter.
In everyday life
Look for Globus cruciger outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
