Serendipity seems to be just another name for the theological concept of Grace
In catholicism
Divine grace is associated with mother Mary
Yet it is deeply rooted from asncient times and accross cultures with events induced by the white Goddess
the mother of all inspiration
See for example white goddess themes such as
When I am in a time of trouble mother Mary comes to me
Tell me words of wisdom, let it be
Or in Hebrew poetry and literature,
loyal lovers of the white Goddess
are Nathan Alterman and Alexander Pen
where Nathan Zach or Avidan are her opponents

Or rather David Avidan betrayed the White Goddess in his later years, which inevitably led to the sisyphian
nature, the effortful non
flowing and uninspired charachter
of his late "art"; and to development of time-chased
sensationism and paranoid features at the night of his life
