Final answer:
Odysseus was NOT regarded as a descendant of Venus by the Romans; Aeneas, Romulus, and Julius Caesar were connected to her lineage or favor in Roman culture.
Step-by-step explanation:
The individual who was NOT regarded as a descendant of Venus by the Romans is D. Odysseus.
Aeneas is a direct descendant of Venus through his Trojan lineage as recounted in Virgil's epic, the Aeneid. The lineage of Romulus, the legendary founder of Rome, is connected to Mars, but because of the close association of the Roman gods and the importance of Venus to Roman culture, he is also considered to be under Venus' favor. Julius Caesar, through the Julian gens, claimed descent from Aeneas, and thereby Venus. Odysseus, however, is a figure from Greek mythology and has no direct connection to Roman lineage or Venus.
