Saint Luke the Evangelist - October 18

Luke the Evangelist (Latin: Lūcās, Ancient Greek: Λουκᾶς, Loukãs, Hebrew: לוקאס, Lūqās, Aramaic: לוקא, Lūqā’) is one of the Four Evangelists—the four traditionally ascribed authors of the canonical Gospels. The early church fathers ascribed to him authorship of both the Gospel according to Luke and the book of Acts of the Apostles, which would mean Luke contributed over a quarter of the text of the New Testament, more than any other author. Prominent figures in early Christianity such as Jerome and Eusebius later reaffirmed his authorship.

The New Testament mentions Luke briefly a few times, and the Pauline epistle to the Colossians refers to him as a physician (from Greek for 'one who heals'); thus he is thought to have been both a physician and a disciple of Paul. Christians since the faith's early years have regarded him as a saint. He is believed to have been a martyr, reportedly as having been hanged from an olive tree, though some believe otherwise.
The Roman Catholic Church and other major denominations venerate him as Saint Luke the Evangelist and as a patron saint of artists, physicians, bachelors, surgeons, students and butchers; his feast day takes place on 18 October.

Relics
Despot George of Serbia bought the relics from the Ottoman sultan Murad II for 30,000 gold coins.en.wikipedia.org/wiki/Luke_the_Evangelist[not in citation given] After the Ottoman conquest of Bosnia, the kingdom's last queen, George's granddaughter Mary, who had brought the relics with her from Serbia as her dowry, sold them to the Venetian Republic.en.wikipedia.org/wiki/Luke_the_Evangelist
In 1992, the then Greek Orthodox Metropolitan Ieronymos of Thebes and Levathia (the current Archbishop of Athens and All Greece) requested from Bishop Antonio Mattiazzo of Padua the return of "a significant fragment of the relics of St. Luke to be placed on the site where the holy tomb of the Evangelist is located and venerated today". This prompted a scientific investigation of the relics in Padua, and by numerous lines of empirical evidence (archeological analyses of the Tomb in Thebes and the Reliquary of Padua, anatomical analyses of the remains, Carbon-14 dating, comparison with the purported skull of the Evangelist located in Prague) confirmed that these were the remains of an individual of Syrian descent who died between 416 BC and AD 72.en.wikipedia.org/wiki/Luke_the_Evangelist The Bishop of Padua then delivered to Metropolitan Ieronymos the rib of Saint Luke that was closest to his heart to be kept at his tomb in Thebes, Greece.en.wikipedia.org/wiki/Luke_the_Evangelist
Thus, nowadays, the relics of Saint Luke are so divided:
The body, in the Abbey of Santa Giustina in Padua;
The head, in the St. Vitus Cathedral in Prague;
A rib, at his tomb in Thebes.
