Sopdet, derived from the Egyptian word 'spdt' meaning 'triangle', which itself comes from 'spd' meaning 'to be sharp' with a feminine suffix 't', is the ancient Egyptian name for the star Sirius. It also represents the personification of Sirius as a goddess in Egyptian mythology. Known to the Greeks as Sothis, Sopdet was often conflated with other deities such as Isis and Anubis.
