Question: Which man born in Dalmatia ordered Genesius of Rome to denounce Christianity
Context: Jiroemon Kimura (木村 次郎右衛門 , Kimura Jirōemon , April 19, 1897 – June 12, 2013) was a Japanese supercentenarian.  He became the oldest verified male in history on December 28, 2012, at the age of 115 years and 253 days when he surpassed the age of Christian Mortensen who died in 1998, and also became the first and so far the only man who indisputably reached 116 years of age, being 116 years, 54 days old at the time of his death from natural causes on June 12, 2013, in a hospital in his hometown of Kyōtango, Kyoto Prefecture, Japan.  He was the last known living man born in the 19th century. Quintus Aurelius Symmachus (c. 345 – 402) was a Roman statesman, orator, and man of letters.  He held the offices of governor of proconsular Africa in 373, urban prefect of Rome in 384 and 385, and consul in 391.  Symmachus sought to preserve the traditional religions of Rome at a time when the aristocracy was converting to Christianity, and led an unsuccessful delegation of protest against Gratian, when he ordered the Altar of Victory removed from the curia, the principal meeting place of the Roman Senate in the Forum Romanum.  Two years later he made a famous appeal to Gratian's successor, Valentinian II, in a dispatch that was rebutted by Ambrose, the bishop of Milan.  Symmachus's career was temporarily derailed when he supported the short-lived usurper Magnus Maximus, but he was rehabilitated and three years later appointed consul.  Much of his writing has survived: nine books of letters; a collection of "Relationes" or official dispatches; and fragments of various orations. Diocletian ( ; Latin: "Gaius Aurelius Valerius Diocletianus Augustus" ), born Diocles (244–312), was a Roman emperor from 284 to 305.  Born to a family of low status in Dalmatia (Roman province), Diocletian rose through the ranks of the military to become roman cavalry commander to the Emperor Carus.  After the deaths of Carus and his son Numerian on campaign in Persia, Diocletian was proclaimed emperor.  The title was also claimed by Carus' other surviving son, Carinus, but Diocletian defeated him in the Battle of the Margus.  Diocletian's reign stabilized the empire and marks the end of the Crisis of the Third Century.  He appointed fellow officer Maximian as Augustus, co-emperor, in 286. Genesius of Rome is a legendary Christian saint, once a comedian and actor who had performed in plays that mocked Christianity.  According to legend, while performing in a play that made fun of baptism, he had an experience on stage that converted him.  He proclaimed his new belief, and he steadfastly refused to renounce it, even when the emperor Diocletian ordered him to do so. The Edict of Thessalonica (also known as Cunctos populos), issued on 27 February 380 AD by three reigning Roman Emperors, ordered all subjects of the Roman Empire to profess the faith of the bishops of Rome and of Alexandria, making Nicene Christianity the state religion of the Roman Empire. James Emmanuel "Doc" Sisnett (22 February 1900 – 23 May 2013) was a Barbadian supercentenarian.  Born and raised in Saint George, he spent his life as a blacksmith, sugar factory worker, and farmer, not retiring from the latter until he turned 100.  In excellent health throughout his life, he died at the age of 113 years, 90 days and held a number of distinctions.  Among them, he was the verified oldest man in the Western Hemisphere, the second-oldest man in the world, and the last surviving black man born in the 19th century.  He was also the only verified supercentenarian from Barbados and, along with Jiroemon Kimura (who died 20 days after Sisnett), one of the last men born in the 19th century. Celidonius is the traditional name ascribed to the man born blind whom Jesus healed in the Gospel of John .  This tradition is attested in both Eastern Christianity and in Catholicism. Saint Ilid is a semi-legendary saint of Wales.  He has at times been identified as Joseph of Arimathea, perhaps because he is referred to as a "man of Israel" and to have been born Jewish.  Moreover, he is said to have returned from Rome with "Caratacus", Saint Cyllin and Eigen and formed a religious college of twelve named "Cor Eurgain" (the choir of Eurgain), suggesting the early entry of Christianity into Britain.  He may be commemorated in the village Llanilid.  According to Thomas Morgan, Llanilid follows the tradition of Welsh place names attached to a parish in taking its title from the saint to whom the local church is dedicated.  In Llanilid the local church is St. Ilid & St Cruig's church, and Morgan states that this relates to Ilid a person who introduced Christianity to Wales in the 1st century.  This research may be connected to that of famed literary forger Iolo Morganwg, who produced elaborate tales of Ilid going as far as stating that it was the Welsh names of Joseph of Arimathea.  Morgan relates that "Llan" – "Ilid", refers to the 'parish of St Ilid'.  This has been challenged by R. W. D. Fenn, who, after studying the "Book of Llandaff" and Nennius's "Historia Brittonum" writes in 1962 that the Latin equivalent of Ilid represents the name of a district, similar to Llandovery, and not a person.  Fenn then writes that in 1566 Llanilid was dedicated to Ilid and Curig, whom he connects to the saints more commonly known in Christian tradition as Julietta and Quiricus.  He links this through the Appendix of the "Book of Llandaff" which states that the church at Llanilid is first given as the 'Church of St Julitta'. Giovanni Dalmata (c. 1440 – c. 1514), born Ioannes Stephani Duknovich de Tragurio and also known as "Giovanni Duknovich di Traù" and "Ivan Duknović", was a sculptor from Trogir, Dalmatia who was mainly active in Rome, Hungary and in Dalmatia.  Giovanni Dalmata was, with Mino da Fiesole and Andrea Bregno, the leading sculptor in Rome in the second half of the 15th century. Claude Stanley Choules ( ; 3 March 1901 – 5 May 2011) was an English-born military serviceman from Perth, Australia who at the time of this death was the oldest combat veteran of the First World War from England, having served with the Royal Navy from 1915 until 1926, after having emigrated to Australia he served with the Australian Royal Navy, from 1926 until 1956, as a Chief Petty Officer and was a naturalised Australian citizen.  He was the last surviving military witness to the scuttling of the German fleet in Scapa Flow in 1919.  He was also the last surviving veteran to have served in both world wars, at the time of his death, he was also the third-oldest verified military veteran in the world and the oldest known living man in Australia.  He was the seventh-oldest living man in the world.  Choules became the oldest man born in the United Kingdom following the death of Stanley Lucas on 21 June 2010.  Choules died in at the age of 110 years and 63 days.  He had been the oldest British-born man; following his death, that honour went to Reverend Reginald Dean.  In December 2011, the landing ship HMAS "Choules" was named after him, only the second Royal Australian Navy vessel named after a sailor.
