Professor emeritus at Occidental College and the leader of an international folkdance ensemble,
prepositional phrase (modifier) of the next sentence where we do have SHE. Therefore SHE was a professor AND a leader of something (who cares)
she has described her (i)
scholarly work as standing at the crossroads of archeology and linguistics.
Her scholarly work I.E: her work as a professor was described as a mix between archeology and linguistics
This work, however, is not a (ii)
social history but rather an excavation of myth and legend that draws attention to tantalizing traces of dancing in the shape of agrarian ritual and then leaps into (iii)
mystery.
Nonetheless, this work (I guess her actual work) has not a connotation of a social history work rather a dive, a focus on myth and legend which turns out put attention on the ritual of the agrarian and turns out (second step) into a mystery of this ritual
Basically the meaning could visualize this way: her work put deep attention on the ritual and when we focus on this attention the result is much deeper and in-depth attention down to the mystery. See it as you descend into a black hole
Hope this helps
