What is "medesicaste"

In Greek mythology, the name Medesicaste refers to two women of the Trojan royal house:

• Medesicaste, a daughter of Laomedon and thus a sister of Priam. Together with her sisters Aethilla and Astyoche, she was taken captive by the Greeks after the end of the Trojan War; the three sisters set fire to the Greek ships, causing the crew to remain and settle at the place they were staying at (either Italy or Thrace).
• Medesicaste, an illegitimate daughter of Priam and wife of Imbrius.
