Reference excerpt

The Miracle of the Sun (Portuguese: Milagre do Sol), also known as the Miracle of Fátima, is a series of events reported to have occurred miraculously on 13 October 1917, attended by a large crowd (generally estimated to be in the high tens of thousands) who had gathered in Fátima, Portugal, in response to a prophecy made by three shepherd children, Lúcia Santos and Francisco and Jacinta Marto. The prophecy was that the Virgin Mary (referred to as Our Lady of Fátima) would appear and perform miracles on that date. Newspapers published testimony from witnesses who said that they had seen extraordinary solar activity, such as the Sun appearing to "dance" or zig-zag in the sky, advance towards the Earth, or emit multicolored light and radiant colors. According to these reports, the event lasted approximately ten minutes. The local bishop opened a canonical investigation of the event in November 1917, to review witness accounts and assess whether the alleged private revelations from Mary were compatible with Catholic theology. The local priest conducting the investigation was particularly convinced by the concurring testimony of extraordinary solar phenomena from secular reporters, government officials, and other skeptics in attendance. Bishop José da Silva declared the miracle "worthy of belief" on 13 October 1930, permitting "officially the cult of Our Lady of Fátima" within the Catholic Church. At a gathering on 13 October 1951 at Fátima, the papal legate, Cardinal Federico Tedeschini, told the million people attending that on 30 October, 31 October, 1 November, and 8 November 1950, Pope Pius XII himself witnessed the miracle of the Sun from the Vatican gardens. The early and enduring interest in the miracle and related prophecies has had a significant impact on the devotional practices of many Catholics. There has been much analysis of the event from critical sociological and scientific perspectives. According to critics, the eyewitness testimony was actually a collection of inconsistent and contradictory accounts. Proposed alternative explanations include witnesses being deceived by their senses due to prolonged staring at the Sun and then seeing something unusual as expected.

Background

In the spring of 1916, three Catholic shepherd children near Fátima reported visions of an angel. Beginning in May 1917, they also experienced apparitions of the Virgin Mary, whom they called the Lady of the Rosary. The children claimed the Lady prophesied that prayer would bring an end to the Great War, and that on 13 October that year, she would reveal her identity and perform a miracle "so that all may believe." Newspapers reported the prophecies, and many pilgrims began visiting the area. The children's accounts were deeply controversial, drawing intense criticism from both local secular and religious authorities. A provisional administrator briefly took the children into custody, believing the prophecies were politically motivated in opposition to the officially secular First Portuguese Republic established in 1910.

The event

Various claims have been made regarding the events that transpired. Many witnesses reported that after a period of rain, the dark clouds parted, revealing the Sun as an opaque, spinning disc in the sky. It was described as being significantly duller than usual, casting multicolored lights across the landscape, the people, and the surrounding clouds. The Sun was then reported to have careened towards the earth before zig-zagging back to its normal position. Witnesses reported that their previously wet clothes became "suddenly and completely dry, as well as the wet and muddy ground that had been previously soaked because of the rain that had been falling". Not all witnesses reported seeing the Sun "dance". Some people only saw the radiant colors, while others claimed to see the Virgin Mary. A number of people saw nothing. According to some estimates, the total crowd of observers was made up of about 70,000 people, while other sources state that there were 50,000 witnesses. Skeptic Brian Dunning commented on an image commonly mistaken for a photograph of the Sun taken at Fátima: "An old black and white photograph of the actual sun miracle event shows a lot of dark rain clouds behind some trees and the sun poking through. There is certainly nothing in the photograph that looks unusual, but of course a photograph is static. Whatever the crowd saw was not interesting enough to be noticeable in a photograph". The photograph, originally published in 1951 by L'Osservatore Romano was subsequently determined to have been taken approximately eight years later in a different Portugal town of a different solar phenomenon. The misattributed image, however, continues to circulate on the internet, but EWTN acknowledges it is not from the events of Fátima. The three children (Lúcia dos Santos and her cousins Jacinta and Francisco Marto) who originally claimed to have seen Our Lady of Fátima also reported seeing a panorama of visions, including those of Jesus, Our Lady of Sorrows, Our Lady of Mount Carmel, and Saint Joseph blessing the people. In the fourth edition of her memoirs, written in 1941, Lúcia said that on the occasion of their third visit to the Cova da Iria, on 13 July 1917, she asked the Lady to tell them who she was, and to perform a miracle so that everyone would believe. The Lady told her that they should continue to come to the Cova each month until October, when the requested miracle would occur.

De Marchi accounts

Descriptions of the events reported at Fátima were collected by Father John De Marchi, an Italian Catholic priest and researcher. De Marchi spent seven years in Fátima, from 1943 to 1950, conducting research and interviewing the principals at length. In The Immaculate Heart (1952), De Marchi reported that, "[t]heir ranks (those present on 13 October) included believers and non-believers, pious old ladies and scoffing young men. Hundreds, from these mixed categories, have given formal testimony. Reports do vary; impressions are in minor details confused, but none to our knowledge has directly denied the visible prodigy of the sun."

De Marchi authored several books on the subject, such as The True Story of Fátima. They include a number of witness descriptions:

Worked examples

Example 1 — a first encounter with Miracle of the Sun

Start with the simplest possible case. Write down what Miracle of the Sun 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 Miracle of the Sun 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 Miracle of the Sun 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 Miracle of the Sun

In research
Miracle of the Sun 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 Miracle of the Sun 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
Miracle of the Sun is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1917 in Christianity, 1917 in Portugal, 20th century in Catholicism, so understanding it makes those chapters shorter.
In everyday life
Look for Miracle of the Sun 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.
