Helenus (son of Priam)

Hecuba comforts Cassandra, the male figure at the far right is apparently Helenus, interpreting the same omen as Cassandra.

In Greek mythology, Helenus (/ˈhɛlənəs/; Ancient Greek: Ἕλενος, romanized: Hélenos, lit. 'bright', 'shining light' or 'torch') was a gentle and clever seer. He was also a Trojan prince as the son of King Priam and Queen Hecuba of Troy, and the twin brother of the prophetess Cassandra.
