What is "と...との"doing in this sentence?


I was reading the book "刺青殺人事件" and came across this section:

> しかし、そういう標本のどれにもまして、この一室を訪れて来る人々の注意を完全に奪ってしまうものは、壁を埋めてかかげられた刺青人皮のほかにはない。
> それは奇妙なアラベスク、刺青師 **と** 、この芸術の愛好者 **との** 魂を、死後にとどめた曼陀羅図。

I initially interpreted this as "...the mandala that keeps the soul of the
tattooist and the fanatics of this artform posthumously", but I then wondered
that if that was the case, why wasn't it written like "刺青師とこの芸術の愛好者の魂を..."
instead. After researching for a bit I still don't get what it means, and I
guess staring at this sentence for more than 15 minutes is messing with my
head, because now I am starting to wonder why the first part "arabesque" don't
feel connected to the "mandala" at the end.




As I put in the comment, と for listing things is used originally as 'AとBと'
although nowadays it appears usually as 'AとB'.

The last sentence has the structure
それは奇妙なアラベスク、（刺青師と、この芸術の愛好者との魂を、死後にとどめた）曼陀羅図, where （刺青師...とどめた) is a relative
clause modifying 曼陀羅図. The 、 after アラベスク expresses the listing here.
Verbosely, it could be written as それは奇妙なアラベスク **であり**
、刺青師と、この芸術の愛好者との魂を、死後にとどめた曼陀羅図 **である**.
