Mark

You might begin by reading the gnostic gospel of Mary Magdalene. Most scholars have agreed a composition date of the second century AD which makes it at least contemporaneous with some of the datings of the canonical gospels. Information about the codex and the text of the gospel in English can be found here:

Magdalene is also referenced in the gnostic gospel of Philip as Jesus' "companion"

Quote

There were three who always walked with the Lord: Mary, his mother, and her sister, and Magdalene, the one who was called his companion. His sister and his mother and his companion were each a Mary.

Now, the interesting thing for me is that when these texts were denounced as heretical in 325AD, Mary's importance in Jesus' ministry was effectively erased by men. To add insult to injury, less than 300 years later her reputation is further besmirched by a Pope who conflated different Marys - understandable given that much of the earlier, arguably more reliable detail, had been excised by men who sought to marginalise and exclude women from positions of power.

Happy reading.

Her name in Hebrew is Mary of Magdala, giving credence to the fact that 'the Magdalene' was from Magdala Nunaaya which is the location Matthew records
