An authority on Loreto has summed up the controversy concerning the miraculous flight of the Holy House by writing that it has attracted "the ridicule of one half of the world and the devotion of the other." Other Christian sources describe Hebrew and Greek
graffiti on the walls, which they compare to writings found at the
Grotto of the Annunciation in Nazareth. A sixteenth-century investigation ordered by
Pope Clement VII reported that the house's measurements exactly matched those of foundations in front of the Grotto in Nazareth. Finally, apologists cite the house's placement partly on a public road, arguing that a house would not be deliberately built in such a location.
Earliest mentions of the house The documented history of the house can only be traced as far back as the close of the
Crusades, around the 14th century. An early brief reference is made in the of
Flavius Blondus (1392–1463), secretary to Popes
Eugene IV,
Nicholas V,
Calixtus III and
Pius II; it can be read in its entirety in the , contained in the (1576) of
Baptista Mantuanus. The first detailed mention of the tradition is a 1472 leaflet by Teramano. There are 16th-century bas-reliefs, which suggest that the Holy House was transported by sea. In May 1900, papal physician Giuseppe Lapponi indicated that he had read in the Vatican archives documents suggesting that the members of the noble Byzantine family named Angelos had saved the stones of the House from Muslim devastation and transported them to Loreto. In a second step, in late 1294,
Nikephoros, ruler of Epirus from the Angelos family (in Italian: ), sent on the bricks to Italy as a wedding gift for his
daughter who had married
Prince Philip, the son of the
King of Naples, in October that year. The stones considered by researchers to be authentic are still visibly marked with Roman numerals, by scratching or with coal, which suggests that the three walls were carefully taken apart with the intention to faithfully reassemble them at another location.
Counter-arguments: chronology and late origin According to
Herbert Thurston, in some respects, the Lauretan tradition is "beset with difficulties of the gravest kind", which were noted in a 1906 work on the subject. There are documents which indicate that a church dedicated to the Blessed Virgin already existed at Loreto in the 12th and 13th centuries, at least a century before the supposed translation. There is no mention by early pilgrims or other sources of a building at the venerated site in Nazareth, other than the rock-hewn chamber. Neither does any document from the time following the alleged transition mention any missing structure at the site. There is also no mention of the alleged transition before 1472, 180 years after the time of the supposed translation.
Statue-before-house-legend theory Thurston suggests that a
miracle working statue or picture of the Madonna was brought from Tersatto in
Illyria (more precisely Dalmatia) to Loreto by some pious Christians and was then confounded with the ancient rustic chapel in which it was harboured, the veneration formerly given to the statue afterwards passing to the building. ==Vision of Blessed Anne Catherine Emmerich==
