John Tzetzes

John Tzetzes' Scholia on Lycophron asserted that Cassandra's reference to Porceus in Lycophron's Alexandra signalled Laocoön's fate.

He also asserted that Laocoön's death took place in the temple of the Thymbraean Apollo, which is where Euphorion had located Laocoön's crime (sexual intercourse). This creates a mirroring of crime and punishment. Tzetzes' source for this specific assertion is unknown.
