John Turner also has republished an essay on The Head of John the Baptist in The Anxious Bench

Incidentally, Salome is not actually mentioned by name in the New Testament accounts of the beheading of John the Baptist. One reading in Mark 6:22 gives the name of the daughter as the same as her mother, "Herodias." But this may be a mistake for a reference to her as the daughter of Herodias. Scholars generally seem to read the New Testament story alongside Josephus's and identify the daughter as Salome.
