Virgil of Salzburg

Virgil of Salzburg is a astronomy 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 Virgil of Salzburg rather than just read about it. In short: Virgil (c. 700– 27 November 784), also spelled Vergil, Vergilius, Virgilius, Feirgil or Fearghal, was an Irish priest and early astronomer. He left Ireland around 745, intending to visit the Holy Land; but, like many of his countrymen, he settled in Francia.

Key takeaways

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

Reference excerpt

Virgil (c. 700– 27 November 784), also spelled Vergil, Vergilius, Virgilius, Feirgil or Fearghal, was an Irish priest and early astronomer. He left Ireland around 745, intending to visit the Holy Land; but, like many of his countrymen, he settled in Francia. Virgil served as abbot of Aghaboe, bishop of Ossory and later bishop of Salzburg. He was called "the Apostle of Carinthia" and "the geometer".

Biography He originated from a noble family of Ireland, where his name was Feirgil or Fearghal, and is said to have been a descendant of Niall of the Nine Hostages. Feirgil was probably educated at the Iona monastery. In Annals of the Four Masters and Annals of Ulster, he is referenced as the Abbot of Aghaboe, in County Laois, where he was known as "the Geometer" because of his knowledge of geography. Around 745, he left Ireland, intending to visit the Holy Land; but, like many of his countrymen, who seemed to have adopted this practice as a work of piety, he settled down in France, where he was received with great favour by Pippin the Younger, who was then Mayor of the Palace under Childeric III of Franconia. He was an adviser to Pippin. He probably used a copy of the Collectio canonum Hibernensis (an Irish collection of canon law) to advise him to receive royal unction in 751, to assist his recognition as king Pippin III after the deposition of Childeric. After spending two years at Cressy, near Compiègne, he went to Bavaria, at the invitation of Duke Odilo, where he founded the monastery of Chiemsee, and within a year or two, was made Abbot of St Peter's Abbey at Salzburg. Among his notable accomplishments was the conversion of the Alpine Slavs to Christianity; he also sent missionaries to Hungary. As Abbot of St Peter's, he clashed with Saint Boniface. A priest having, through ignorance, conferred the Sacrament of Baptism using, in place of the correct formula, the words "Baptizo te in nomine patria et filia et spiritus sancti" (instead of "Baptizo te in nomine patris et filii et spiritus sancti"), Vergilius held that the sacrament had been validly conferred, but Boniface complained to Pope Zachary. The latter, however, decided in favour of Virgil. Later on, Boniface accused Virgil of spreading discord between himself and Duke Odilo of Bavaria and of teaching a doctrine in regard to men descended not from Adam, which was "contrary to the Scriptures". Pope Zachary's decision in this case was that "if it shall be clearly established that he professes belief in another world and other people existing beneath the earth, or in [another] sun and moon there, thou art to hold a council, and deprive him of his sacerdotal rank, and expel him from the church." The treatise in which Virgil expounded his doctrine no longer exists. Two things, however, are certain: first, that there was involved the problem of original sin and the universality of redemption; secondly, that Virgil succeeded in freeing himself from the charge of teaching a doctrine contrary to Scripture. It is likely that Boniface, already biased against Virgil because of the preceding case, misunderstood him, taking it for granted, perhaps, that if there are antipodes, the "other race of men" are not descendants of Adam and were not redeemed by Christ. After the martyrdom of Boniface, Virgil was made Bishop of Salzburg in 766 or 767 and laboured successfully for the upbuilding of his diocese as well as for the spread of Christianity in neighbouring heathen countries, especially in Carinthia.

Veneration

He is venerated as a saint in both the Catholic Church and the Eastern Orthodox Church. In 1233, he was formally canonized by Pope Gregory IX. His doctrine that the earth is a sphere was derived from the teaching of ancient geographers, and his belief in the existence of the antipodes was probably influenced by the accounts which the ancient Irish voyagers gave of their journeys. This, at least, is the opinion of Rettberg (Kirchengesch. Deutschlands, II, 236).

Dedications Aside from being personally associated with Aghaboe Abbey and Salzburg Cathedral, a number of parishes around the world are dedicated to him, mostly being founded by small populations of far-flung Irish Catholics, like himself. There is a church dedicated to him in Broad Channel, Queens, New York, which merged with another parish in 2008. A parish in Morris Plains, New Jersey, is also dedicated to him. Fittingly for this Irish geometer who predicted antipodes, several churches in the Southern Hemisphere are dedicated to him. St Virgil's College in Hobart, Tasmania is named for him. There was a St Virgilius Church in Balclutha, New Zealand designed by Francis Petre which moved and was re-dedicated to Mary MacKillop, however the new chapel remains dedicated to Virgilius.

Art and culture A large marble statue of him stands outside the doors of Salzburg Cathedral. A stained-glass window of St Virgil contemplating the antipodes sits in St John's College, University of Sydney. Sebastian Stief painted him amidst Salzburg's construction, Alec Szolomiak painted him, as did Jan Toorop, and Dhiraja McBryde. Yalumba, Australia's oldest family-owned winery, produces a Viognier named Virgilius.

Worked examples

Example 1 — a first encounter with Virgil of Salzburg

Start with the simplest possible case. Write down what Virgil of Salzburg claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Virgil of Salzburg 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 Virgil of Salzburg 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 Virgil of Salzburg

In research
Virgil of Salzburg appears in astronomy 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 Virgil of Salzburg 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
Virgil of Salzburg is common in secondary-school and first-year university syllabi. It links to neighbouring topics 784 deaths, 8th-century Frankish saints, 8th-century Frankish writers, so understanding it makes those chapters shorter.
In everyday life
Look for Virgil of Salzburg 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.
