Can we at least recall that these are both fragments of the great lost epic cycle?
The eternal #1 in the list of lost books I want found:The full Greek Epic Cycle of Troy, much of which is lost, except in fragments and later summaries. The eight works together told the entire history of the Trojan War in epic verse.
1. Cypria (11 books by Stasinus): the events leading up to the Trojan War and the first nine years of the conflict, especially the Judgement of Paris.(fifty lines remain of the original text)
2. Iliad (24 books by Homer): Achilles' rage against first king Agamemnon and then the Trojan prince Hector, ending with Achilles killing Hector in revenge for the death of Patroclus and Priam coming to Achilles to ransom Hector's body. (full manuscripts remain of the original text)
3. Aethiopis 5 books by Arctinus): the arrival of the Trojan allies, Penthesileia the Amazon and Memnon; their deaths at Achilles' hands in revenge for the death of Antilochus; Achilles' own death. (only five lines remain of the original text)
4. Ilias Mikra ("Little Iliad" 4 books by Lesches): events after Achilles' death, including the building of the Trojan Horse and the Awarding of the Arms to Odysseus. (nearly thirty lines remain of the original text)
5. Iliou persis ("Sack of Troy" 2 books by Arctinus): the destruction of Troy by the Greeks. (only ten lines remain of the original text)
6. Nostoi ("returns" 5 books by Agias or Eumelus): the return home of the Greek force and the events contingent upon their arrival, concluding with the returns of Agamemnon and Menelaus. (five and a half lines remain of the original text)
7. Odyssey (24 books by Homer): the end of Odysseus' voyage home and his vengeance on his wife Penelope's suitors, who have devoured his property in his absence.(full manuscripts remain of the original text)
8. Telegony (2 books by Eugammon): Odysseus' voyage to Thesprotia and return to Ithaca, and death at the hands of an illegitimate son Telegonus. (only two lines remain of the original text)
Maybe someday... from Oxyrhynchus or another treasure-trove.
