'''Januarius''' ({{IPAc-en|ˌ|dʒ|æ|n|.|j|u|ˈ|ɛər|i|ə|s}} {{respell|JAN|yoo|AIR|ee|əs}};<ref>{{cite EPD|18}}</ref> {{langx|la|Ianuarius}}; [[Neapolitan language|Neapolitan]] and {{langx|it|Gennaro}}), also known as {{nowrap|'''Januarius I of Benevento'''}}, was [[Roman Catholic Archdiocese of Benevento|Bishop of Benevento]] and is a [[Christian martyrs|martyr]] and [[saint]] of the [[Catholic Church]], [[Eastern Orthodox Church]], and [[Armenian Apostolic Church]]. While no contemporary sources on his life are preserved, later sources and [[Christian legend|legends]] claim that he died during the [[Great Persecution]],<ref name="cathenc"/> which ended with [[Diocletian]]'s retirement in 305.

Januarius is the patron saint of [[Naples]], where the faithful gather three times a year in [[Naples Cathedral]] to witness the [[liquefaction]] of what is claimed to be a sample of his blood kept in a sealed glass [[ampoule]].

{{anchor|Biography|History}}

==Life==
Little is known of the life of Januarius,<ref name="cathenc">{{Cite CE1913 | wstitle =St. Januarius | author =Herbert Thurston}}</ref> and what follows is mostly derived from later Christian sources, such as the ''Acta Bononensia'' (BHL 4132, not earlier than 6th century) and the ''Acta Vaticana'' (BHL 4115, 9th century), and from later folk traditions.

===Legend===
[[File:Napoli-Ribera-San-Gennaro.jpg|thumb|left|Ribera, ''[[Saint Januarius Emerges Unscathed from the Furnace]]'', Naples Cathedral]]
According to various [[hagiographies]], Januarius was born in [[Benevento]] to a rich patrician family that traced its descent to the [[Caudini]] tribe of the [[Samnites]]. At a young age of 15, he became local priest of his parish in Benevento, which at the time had only a small Christian community. When Januarius was 20, he became [[Bishop of Naples]] and befriended [[Juliana of Nicomedia]] and [[Saint Sossius|Sossius]] whom he met during his studies for the priesthood. During the {{frac|1|1|2}}-year-long persecution of Christians by Emperor [[Diocletian]], he hid some of his fellow Christians and prevented them from being caught. But while visiting Sossius in jail, he too was arrested. He and his colleagues were condemned to be thrown to wild bears in the [[Flavian Amphitheater (Pozzuoli)|Flavian Amphitheater]] at [[Pozzuoli]], but the sentence was changed due to fear of public disturbance, and they were instead beheaded at the [[Solfatara (volcano)|Solfatara]] crater near Pozzuoli.{{refn|group=n|For further details on these locations, see the ''[[Catholic Encyclopedia]]''{{'}}s article on "Saint Januarius".<ref name="cathenc"/>}} Other legends state either that the wild beasts refused to eat him, or that he was thrown into a furnace but came out unscathed.

===History===
The earliest historical reference to Januarius is contained in a letter by Uranius, [[bishop of Nola]], dated to c.e 432 on the death of his mentor [[Paulinus of Nola]],<ref name=yuri>Uranius Nolanius (432), ''De Vita et Obitu Paulini Nolani''.  Published by [[Surius]] as ''Epistola "De Obitu Sancti Paulini" ''[http://www.documentacatholicaomnia.eu/04z/z_0432-0432__Urbanus_Presbyter__Epistola_%27De_Obitu_Sancti_Paulini%27_%5BEx_Surio%5D__MLT.pdf.html Online version] accessed on 2009-06-20.</ref><ref>{{usurped|1=[https://web.archive.org/web/20091106143025/http://www.ancientlibrary.com/smith-bio/3617.html "Uranius"]}} in ''Dictionary of Greek and Roman Antiquities'' edited William Smith (1870).</ref> where it is stated that the ghosts of Januarius and [[Martin of Tours]] had appeared to Paulinus three days before his death in 431. About Januarius, the account says only that he was "bishop as well as martyr, an illustrious member of the Neapolitan church".{{refn|group=n|Latin: ''{{lang|la|Ianuarius, episcopus simul et martyr, Neapolitanae urbis illustrat ecclesiam}}''.<ref name=yuri/>}}  The Acta Bononensia says that "At Pozzuoli in Campania [is honored the memory] of the holy martyrs Januarius, Bishop of Beneventum, Festus his [[deacon]], and Desiderius [[lector]], together with [[Saint Sossius|Sossius]] deacon of the church of [[Misenum]], [[Proculus of Pozzuoli|Proculus]], deacon of [[diocese of Pozzuoli|Pozzuoli]], Eutyches, and Acutius, who after chains and imprisonment were beheaded under the emperor [[Diocletian]]".<ref name="cathenc"/>

===Celebrations===
{{main|Feast of San Gennaro}}
[[File:Spadaro eruzione vesuvio.jpg|thumb|San Gennaro procession in Naples, 1631]]
The [[Feast of San Gennaro]] is celebrated on 19 September in the [[General Roman Calendar]] of the Catholic Church.<ref>"Martyrologium Romanum" (Libreria Editrice Vaticana, 2001 {{ISBN|88-209-7210-7}}).</ref>{{refn|group=n|In the 1498 Roman martyrology, his martyrdom took place on the thirteenth day before the [[kalends]] of October or 19 September.<ref>J.

According to an early [[hagiography]],{{refn|group=n|Hagiographies of St Januarius are compiled in the 6th volume of the ''Acta Sanctorum Septembris''.<ref>{{citation |editor-first=J. |editor-last=Carnandet |location=Paris |date=1867 |pages=761–892 |title=Acta Sanctorum Septembris, ''Vol. VI'' }}. {{in lang|la}}</ref>}} Januarius's [[relic]]s were transferred by order of [[Severus of Naples|Severus]], [[Bishop of Naples]], to the [[Catacombs of San Gennaro|Neapolitan catacombs]] "[[extra moenia|outside the walls]]" (''{{lang|la|extra moenia}}'').<ref>Norman (1986), p. 331</ref>{{refn|group=n|A condensed account of the removals of the relics is given by [[Diana Norman|Norman]].<ref>{{citation |last=Norman |first=Diana |contribution=The Succorpo in the Cathedral of Naples: 'Empress of All Chapels' |title=Zeitschrift für Kunstgeschichte, ''Vol.&nbsp;49, No.&nbsp;3'' |date=1986 |pages=323–355 }}.</ref>}} In the early ninth century the body was moved to [[Benevento|Beneventum]] by [[Sico of Benevento|Sico]], [[princes of Benevento|prince]] of [[principality of Benevento|Benevento]], with the head remaining in Naples. Subsequently, during the turmoil at the time of [[Frederick I, Holy Roman Emperor|Frederick Barbarossa]], his body was moved again, this time to the [[Territorial Abbey of Montevergine]] where it was rediscovered in 1480.

At the instigation of Cardinal [[Oliviero Carafa]], his body was finally transferred in 1497 to [[Naples]], where he is the city's [[patron saint]]. Carafa commissioned a richly decorated [[crypt]], the ''Succorpo'', beneath the [[Naples Cathedral|cathedral]] to house the reunited body and head properly. The ''Succorpo'' was finished in 1506 and is considered one of the prominent monuments of the [[High Renaissance]] in the city.<ref>Norman 1986:323-355.</ref>

===Blood===
Saint Januarius is famous for the annual liquefaction of his [[blood]], which, according to [[Christian legend|legend]], was saved by a woman called Eusebia just after the saint's death. A chronicle of Naples written in 1382 describes the cult of Saint Januarius in detail, but mentions neither the relic nor the miracle.<ref name="cicap"/><ref name="altamura">(1382) ''Croniche de Inclyta Cità de Napole'' In Altamura, Antonio (ed.), ''Cronaca di Partenope'', Napoli, 1974</ref> The first certain date is 1389, when it was found to have melted.<ref>''Chronicon Siculum'' [1340-1396], ed. Giuseppe De Blasiis, Naples, 1887, p. 85</ref><ref>Norman 1993:332 and note.</ref> Then, over the following two and a half centuries official reports began to appear declaring that the blood spontaneously melted, at first once a year, then twice, and finally three times a year. While the report of the very first incidence of liquefaction did not make any explicit reference to the skull of the saint, soon afterwards assertions began to appear that this relic was activating the melting process, as if the blood, recognizing a part of the body to which it belonged, "were impatient while waiting for its resurrection".<ref>Cesare Baronio, ''Annales Ecclesiastici'', Rome 1594, vol. 2, p. 803.</ref> This explanation was definitively abandoned only in the eighteenth century.<ref>de Ceglia Francesco Paolo, "Thinking with the Saint: The Miracle of Saint Januarius of Naples and Science in Early Modern Europe" in ''Early Science and Medicine'' 19 (2014), p. 133-173''</ref>

Thousands of people assemble to witness this event in Naples Cathedral three times a year: on 19 September (Saint Januarius's Day, commemorating his martyrdom), on 16 December (celebrating his patronage of Naples and its archdiocese), and on the Saturday before the first Sunday of May (commemorating the reunification of his relics).<ref>[http://www.tredy.com/m/museo-chiesa-di-san-gennaro-duomo-napoli-it-20-m.htm Chiesa di San Gennaro - Duomo (Napoli)]</ref>

The blood is also said to spontaneously liquefy at certain other times, such as [[pope|papal]] visits. It supposedly liquefied in the presence of [[Pope Pius IX]] in 1848, but not that of [[John Paul II]] in 1979 or [[Benedict XVI]] in 2007.<ref>{{cite news|title=Blood of St. Januarius liquefies during Francis' visit to Naples|url=http://www.catholicherald.co.uk/news/2015/03/21/blood-of-st-januarius-liquifies-during-franciss-visit-to-naples/|publisher=Catholic Herald|date=March 21, 2015}}</ref> On March 21, 2015, [[Pope Francis]] [[veneration|venerated]] the dried blood during a visit to [[Naples Cathedral]], saying the [[Lord's Prayer]] over it and kissing it. [[Crescenzio Sepe|Archbishop Sepe]] then declared that "The blood has half liquefied, which shows that Saint Januarius loves our pope and Naples."<ref name=Benge>{{cite news|url=http://www.christianpost.com/news/pope-francis-performs-miracle-in-naples-turns-dry-blood-to-liquid-video-136174/|title=Pope Francis Performs 'Miracle' In Naples; Turns Dry Blood to Liquid|publisher=Christian Post|author=Benge Nsenduluka|date=March 23, 2015}}</ref>

====Ritual liquefaction====
[[File:Die Gartenlaube (1860) b 524.jpg|thumb|left|100px|Drawing of the reliquary containing the two ampoules said to hold Januarius' blood, c. 1860]]
The blood is stored in two hermetically sealed small [[ampoule]]s, held since the 17th century in a [[silver]] [[reliquary]] between two round glass plates about 12&nbsp;cm wide. The smaller, cylindrical ampoule contains only a few reddish spots on its walls, the bulk having allegedly been removed and taken to [[Spain]] by [[Charles III of Spain|Charles III]]. The larger, almond-shaped ampoule, with a capacity of about 60 [[milliliter|ml]], is about 60% filled with a dark reddish substance.<ref name="santi">[http://www.santiebeati.it/dettaglio/29200 San Gennaro: Vescovo e martire] (in Italian)</ref><ref name="cicap"/> Separate reliquaries hold bone fragments believed to belong to Saint Januarius.

For most of the time, the ampoules are kept in a bank vault, whose keys are held by a commission of local notables, including the [[mayor]] of Naples; the bones are kept in a [[crypt]] under the main altar of Naples Cathedral. On feast days, all these relics are taken in procession from the cathedral to the [[Santa Chiara (Naples)|Monastery of Santa Chiara]], where the [[archbishop]] holds up the reliquary and tilts it to show that the contents are solid, then places it on the high altar next to the saint's other relics. After intense prayers by the faithful, including the so-called "relatives of Saint Januarius" (''parenti di San Gennaro''), the content of the larger vial typically appears to liquify. The archbishop then holds up the vial and tilts it again to demonstrate that liquefaction has taken place. The announcement of the liquifaction is greeted with at the 13th-century [[Castel Nuovo]]. The ampoules remain exposed on the altar for eight days, while the priests move or turn them periodically to show that the contents remain liquid.<ref name="santi"/> Sir [[Francis Ronalds]] gives a detailed description of the May 1819 ritual in his travel journal.<ref>{{Cite web|url=http://www.sirfrancisronalds.co.uk/naples3.html|title=Sir Francis Ronalds' Travel Journal: Naples and the Miracle|website=Sir Francis Ronalds and his Family|access-date=11 February 2018}}</ref>

The liquifaction sometimes takes place almost immediately, but can take hours or even days. Records kept at the Duomo tell that on rare occasions the contents fail to liquify, are found already liquified when the ampoules are taken from the safe,<ref>"Sangue di San Gennaro liquefatto prima della processione" ''Corriere dell Sera'', 4 May 1997, p.15</ref> or liquify outside the usual dates.<ref name="santi"/>

====Scientific studies====
[[File:Sangue San Gennaro.jpg|thumb|left|The reliquary being held upside-down during 2022 Saint Januarius's Day celebrations, revealing the liquid inside the ampoules]]
While the Catholic Church has always supported the celebrations, it has never formulated an official statement on the phenomenon and maintains a neutral stance about scientific investigations.<ref name="santi"/> It does not permit the vials to be opened, for fear that doing so may cause irreparable damage. This makes close analysis impossible. Nevertheless, a spectroscopic analysis performed in 1902 by Gennaro Sperindeo claimed that the spectrum was consistent with [[hemoglobin]].<ref>Gennaro, Sperindeo and Raffaele Januario (1901), ''Il Miracolo di S. Gennaro'', 3rd ed., Naples, D'Auria, p. 67-72.</ref> A later analysis, with similar conclusions, was carried out by a team in 1989.<ref>F. D'Onofrio; P. L. Baima Bollone; M. Cannas; quoted by [[Michele Cardinal Giordano]] (1990), ''Prolusione'', in ''Proceedings of the Symposium on the VI centenary of the first liquefaction of the blood (1389–1989),'' December 1989, Napoli, Torre del Greco (Napoli), p. 10.</ref>{{unreliable source?|date=October 2015}} However, the reliability of these observations has been questioned.<ref name="cicap"/>  While clotted blood can be liquefied by mechanical stirring, the resulting suspension cannot solidify again.<ref name="cicap"/>

Measurements made in 1900 and 1904 claimed that the ampoules' weight increased by up to 28&nbsp;grams during liquefaction. However, later measurements with a precision balance, performed over five years, failed to detect any variation.<ref name="cicap"/>

Various suggestions for the content's composition have been advanced, such as a material that is [[photosensitive]], [[hygroscopic]], or has a low melting point.<ref>Eusèbe Salverte, ''Des sciences occultes ou essai sur la magie, les prodiges et les miracles'', Paris, Baillière, 1826.</ref><ref>Henri Broch.

Fischer, ''Mysterious Realms'', Buffalo, Prometheus Books, 1993, p 159.</ref>  However, these explanations run into technical difficulties, such as the variability of the phenomenon and its lack of correlation to ambient temperature.<ref name="cicap"/>

In 2010, Giuseppe Geraci, a professor in the Department of Molecular Biology at Naples's [[Universita Federico II|Frederick II University]], conducted an experiment on a vial containing old blood—a relic dating back to the 18th century from the ''Eremo di Camaldoli'' near [[Arezzo]] in [[Tuscany]]—having the same characteristics of the blood of St. Januarius.<ref>{{cite news  | title =San Gennaro, spunta una seconda ampolla con dentro il sangue | publisher =Metropolis Web | date = 2010-02-05 | url =http://www.metropolisweb.it/Notizie/Campania/Cronaca/san_gennaro_spunta_seconda_ampolla_dentro_sangue.aspx | access-date =2013-09-23 | location=Naples}}</ref> Prof. Geraci showed that the Camaldoli relic also contains blood that can change its solid-liquid phase by shaking.<ref name="Piedimonte">{{cite news  | last =Piedimonte | first =Antonio Emanuele | title =Geraci, la rivelazione 11 anni fa al Corriere "Il sangue c'è e l'ho visto, il miracolo no" | publisher =RCS Corriere del Mezzogiorno | date = 2010-02-05 | url =http://corrieredelmezzogiorno.corriere.it/napoli/notizie/arte_e_cultura/2010/5-febbraio-2010/geraci-rivelazione-11-anni-fa-corriere-il-sangue-c-e-ho-visto-miracolo-no-1602412830498.shtml | access-date =2013-09-23 | location=Naples}}</ref> He further reproduced the phenomenon with his own blood stored in the same conditions as the Camaldoli relic. He stated that, "There is no univocal scientific fact that explains why these changes take place. It is not enough to attribute to the movement the ability to dissolve the blood, the liquid contained in the Treasure case changes state for reasons still to be identified."

A book by the historian of science Francesco Paolo de Ceglia recently traced the research of various scientists over the centuries to explain the phenomenon, which, according to him, has a thermal origin, since the (alleged) blood, in September, when the temperature is highest, is already extracted in liquid form from the tabernacle that stores it. In May it takes longer. And in December it takes much longer. This last annual ‘miracle’ did not take place for many years, but lately, with climate change and the rising temperature in Naples, it is happening more and more frequently.<ref>Francesco Paolo de Ceglia, ''The Natural History of a Neapolitan Miracle.

The Treasure of St. Januarius is a collection of magnificent works and donations collected in seven centuries from popes, kings, emperors, famous and ordinary people. According to studies done by a pool of experts who have analyzed all the pieces in the collection, the Treasure of St. Januarius is of higher value than the crown of [[Queen Elizabeth II]] of the [[United Kingdom]] and the [[Tsar of Russia|Tsar]] of [[Tsardom of Russia|Russia]]. The Treasure is a unique collection of art masterpieces, kept untouched thanks to the Deputation of the Chapel of St Januarius, an ancient secular institution founded in 1527 by a vote of the city of Naples, still existing.

Today, the Treasure is exhibited in the [[Museum of the Treasure of St. Januarius]], whose entrance is located on the right side of the Dome of Naples, under the arcades. By visiting the museum, the Chapel of San Gennaro is accessible even when the cathedral is closed.<ref>{{citation |url=http://www.museosangennaro.it/ |title=''Official website'' |publisher=Museo San Gennaro }}. {{in lang|it}}</ref>
