Final answer:
Venus creates the anemone flower from the blood of Adonis, symbolizing the transient nature of life and beauty in Greek mythology.
Step-by-step explanation:
The flower created by Venus with the blood of Adonis is the anemone. This mythological tale roots from ancient Greco-Roman culture where Venus, the goddess of love and beauty, is intertwined with the mortal Adonis. The story goes that after Adonis is attacked by a wild boar, Venus's tears mixed with his blood give birth to the anemone flower, symbolizing the fleeting nature of life and beauty, as the anemone is known for its short-lived flowers. The anemone's etymology can also be traced to the Greek word for 'wind', further connecting it to the breath of life and sudden loss as conveyed in the myth.
