Two tailed narimakara. Near Peshawar, Pakistan. 1st century CE. From the museum website: This tray features a two-tailed mermaid on the top. It is thought that the empty bottom half of this tray was used to make offerings to mythical beasts to secure safe passage to the afterlife. Tokyo National Museum, TC-599.
She's very interesting, as she's an outlier in two tailed siren imagery. While she looks like a classic two tailed siren, she was found fairly far east, and early in art. She looks like a sister to Romanesque sirens in continental Europe, but she’s a thousand years younger than them.
Like Scylla, she has a leaf skirt, and grasps her two fish tails in a gesture that goes back to the Scythian goddess and was adopted by the Romanesque siren. Her hair is in braids, and she's likely female, as she looks like she has breasts. Appearing in art related to the afterlife gives her something in common with the Etruscan Scylla, who was thought to escort souls to the afterlife.
She's not the only two tailed merperson from Pakistan. I've found a few other examples, mostly two tailed mermen, like this handsome one in the Chicago Art Institute:
Two-tailed naramakara, 101 CE–300 CE. Gandhara, modern day Pakistan. Currently at the Art Institute of Chicago, US.
