Source-derived summary

Mercurius (Greek: Ἅγιος Μερκούριος, Coptic: Ⲫⲓⲗⲟⲡⲁⲧⲏⲣ Ⲙⲉⲣⲕⲟⲩⲣⲓⲟⲥ, Ge'ez: መርቆሬዎስ, Syriac: ܡܳܪܩܘ̇ܪܝܘ̇ܣ; 224/225 – 250 AD) was a Roman soldier of Greek descent who became a Christian saint and martyr. He was born in the city of Eskentos in Cappadocia, in Eastern Asia Minor (modern-day Turkey). According to Christian tradition, he was the soldier who killed Julian the Apostate during his campaign in Persia. Mercurius was also widely known by his Arabic-language name Abu-Sayfain, Abu-Sifin or Abu-Sefein in Egyptian Arabic (Arabic: أبو سيفين, romanized: Abū Seifēn; Coptic: ⲁⲃⲩⲥⲉⲫⲁⲓⲛ, romanized: Abû-Sefaīn) which means "wielder of two swords", referring to the second sword given to him by the Archangel Michael.

Mercurius was born around 225 AD in Cappadocia (Eastern Asia Minor) into a family of Greek descent. His parents were converts to Christianity and they called him "Philopateer" or "Philopatyr" (a Greek name which means 'Lover of the Father'). They raised him in a Christian manner. When he grew to adulthood (at the age of 17), he enlisted in the Roman army in the reign of Emperor Decius. He gained a great reputation among his superiors as a swordsman and a tactician in many battles.

Editorial summary

This brief starts where responsible research should: with the source description of “Saint Mercurius” as greek soldier and Christian martyr (died 250). Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 206-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The authority record carries competing date values—0224-01-01, 0225-01-01—which should remain separate until their references and qualifiers are resolved. The account is most persuasive where Saint, Mercurius and Greek can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as greek soldier and Christian martyr (died 250). Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 19, 2026. The linked authority identifier is Q1285323. VIAF identifies the subject as 206021770. The Library of Congress control number is nr99008697. 1 of 4 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
