Agapitus (Italian: Agapito) is venerated as a martyr saint, who died on August 18, perhaps in 274,[2] a date that the latest editions of the Roman Martyrology say is uncertain.

[3] According to his legend, 16-year-old Agapitus, who may have been a member of the noble Anicia family of Palestrina,[2] was condemned to death, under the prefect Antiochus and the Emperor Aurelian, for being a Christian.

"[4] Around the 5th century, Pope Felix III built a basilica in his honour on the supposed site of his martyrdom.

Agapitus is honoured in the Tridentine calendar by a commemoration added to the Mass and canonical hours in the liturgy of the day within the Octave of the Assumption.

Accordingly, in the General Roman Calendar of 1960 the celebration of Saint Agapitus appears as a commemoration in the ordinary weekday Mass.
