Sicarius of Brantôme or Sicarius of Bethlehem (Sicaire de Brantôme, Sicaire de Bethléem) was a child saint who was venerated from the time of Charlemagne onwards as one of the victims of the Massacre of the Innocents by Herod the Great,[1][2][3][4] said to have occurred in Bethlehem at the time of the birth of Jesus.

[1] In the 19th century, Sabine Baring-Gould was skeptical and wrote that "how the infant of a Hebrew mother acquired a Latin name has not been attempted to be explained".

[7] This sentiment was echoed in 2014 by Kristan Lawson and Anneli Rufus:The massacre happened a long time ago when Jesus, still a baby himself, hadn't yet developed the following that would turn into Christianity.

[1] Sicarius represents an "impulse to personify the supposedly ancient relic with names may imply a heightened sympathy for the sufferings of the infants, and perhaps for their grieving families as well".

[5][7] St. Memorius (Mémoire) was another child martyr and purported Holy Innocent whose relics were translated during the reign of Charlemagne; they were taken to the Cathedral of St. Front in Périgueux from St. Peter's Basilica in Rome.
