San Menna

In the eighth century, the anonymous pilgrim of Einsiedeln pointed out that there existed a church dedicated to the Egyptian martyr Saint Menas on the Ostian Way, a little before reaching the Basilica of Saint Paul.

[1][2] The church was connected to the famous portico that led from Porta San Paolo into the Ostian Basilica, as is evidenced from the pilgrimage itineraries of the seventh century: inde per porticum usque ad ecclesiam Mennae, et de Menna usque ad s. Paulum Apostolum.

[3] On the Wednesday after the fourth Sunday of Lent, when the station is held at the Basilica of Saint Paul, the collecta was held at this church of San Menna,[1] meaning that the people and ministers of the city would meet there and prepare for the procession into the principal church for the day's liturgy.

[2] At around that time, it is recorded that Gregory the Great (590–604) offered one of his Homilies on the Gospels (XXXVI) there.

[2] In his introduction to the homily, he gives a hint as to the relative location of the church: quia longius ab urbe digressi sumus, ne ad revertendum tardior hora praepediat.
