Saint Mercurius the Bishop is a saint commemorated on 1 Baramhat in the Coptic calendar. The Coptic Encyclopedia identifies him as an ascetic and a bishop. Its listings distinguish him from Mercurius of Caesarea, the soldier-martyr known as Abu Sayfayn, whose principal feast falls on 25 Hatur.

## Overview

**Saint Mercurius the Bishop** is commemorated on **1 Baramhat**. The Coptic Encyclopedia’s listing describes him succinctly as “an ascetic and a bishop,” while its calendar gives the commemorative title “Saint Mercurius the Bishop.” These two notices establish his identity and feast day without supplying a narrative biography.[^1][^2]

The distinction between this saint and other saints named Mercurius is important. In the encyclopedia’s listing, the entry for the ascetic and bishop is immediately followed by a separate entry for **Mercurius of Caesarea**, also called **Abu Sayfayn**, commemorated on **25 Hatur**. The different descriptions and feast days provide the clearest identification of the bishop in the supplied material.[^1]

## Biographical evidence

The direct biographical information consists of two descriptions: Mercurius was an **ascetic** and held the office of **bishop**. The brief notice places these descriptions together but does not explain the relationship or chronology between his ascetic life and his episcopal ministry.[^1]

Neither the saint listing nor the calendar entry names his episcopal see, birthplace, monastery, teachers, or contemporaries. They also give no year of birth, episcopal consecration, or death. A more detailed account of his origins or ministry therefore cannot be reconstructed from these notices.[^1][^2]

The calendar calls him “Saint Mercurius the Bishop” without designating the observance as a martyrdom. This wording differs from the explicitly labeled “Martyrdom of Saint Alexandrus, bishop of Cappadocia” on the same day. The distinction describes how the calendar presents the commemorations; it does not, by itself, establish the circumstances of Mercurius’s death.[^2]

## Liturgical commemoration

### Feast on 1 Baramhat

Both relevant encyclopedia passages agree on **1 Baramhat**: one gives it as Mercurius’s feast day, and the other includes him under that date in the calendar. The agreement connects the calendar’s episcopal title with the listing’s additional identification of him as an ascetic.[^1][^2]

Under 1 Baramhat, the calendar also names **Saint Narcissus, bishop of Jerusalem**, with the date **A.D. 222**, and the **martyrdom of Saint Alexandrus, bishop of Cappadocia**. These are separate commemorations placed alongside Saint Mercurius the Bishop; the entry supplies no biographical connection among them.[^2]

The printed table labels the month “Baramhat (February–March)” and aligns its first day with **25 February**. That is the correspondence printed in this particular table, rather than an independently established modern civil-calendar conversion.[^2]

## Names and distinction from other saints

### Mercurius the ascetic and bishop

The saint listing uses the name **Mercurius**, qualified by the description “an ascetic and a bishop.” The calendar supplies the fuller title **Saint Mercurius the Bishop**. Neither notice gives an Arabic, Greek, or Coptic form of his name.[^1][^2]

### Other saints named Mercurius

The supplied encyclopedia passages distinguish several commemorations associated with this name:

- **Mercurius the Bishop — 1 Baramhat:** identified as an ascetic and bishop.[^1][^2]
- **Mercurius of Caesarea — 25 Hatur:** also called **Abu Sayfayn** or **Marqurah**, identified as a popular soldier-saint martyred under **Decius**.[^3]
- **Mercurius — 18 Tut:** identified as a martyr under **Julian the Apostate**.[^4]
- **Mercurius and Ephraem — 30 Abib:** identified as natives of **Akmim** and monks of the **Thebiad**, who opposed the Arians and were killed by them.[^3]

These entries show why the name alone is insufficient for identification. For the bishop, the combination of **episcopal title**, **ascetic description**, and **1 Baramhat** is the essential reference point; the military identity and 25 Hatur commemoration belong to the separately listed Mercurius of Caesarea.[^1][^3]
