Dear Dominik,
Thank you for clearing this up.  Somehow I missed Michael's footnote.

Does anyone have a pdf of those two articles  referred to:

 Theodore N. Proferes, “The Relative Chronology of the nivids and praiṣas and the Standardisation of Vedic Ritual.” IIJ 57 (2014): 199–221, doi: 10.1163/15728536-05703013.

Marion Rastelli, “Mahālakṣmī. Integrating a Goddess into the Ahirbudhnyasaṃhitā.” IIJ 58 (2015): 325–356, doi: 10.1163/15728536-05804002.

Thanks,

Harry Spier
