Meaning & History
This was the name of a Zoroastrian deity, who at first was responsible for bringing rainfall and fertility, but later became an astral deity that was associated with what is now the star Sirius. The name may have been derived from Avestan tištriia, which in turn came from púṣiya (via dissimilation) "he who makes prosper" or from Indo-European tri-str-o-m "group of three stars".
