Hiller 2011: festival name in -te-ri-jo (cf. Anthestēria1, Pluntēria2), 'girding of persons offered to a deity'?
Chadwick & Ventris 1973: if po-re-no + zo-te-ri-ja, zo-te-ri-ja "might then be tsōtēria (σωτήρια) 'ransom of victim, prisoner, or the like'." (see reference for further discussion of problems with this)
