I want to know the answer to the following question:
Who blew the discus off course, killing Hyacinthus?
All the background I'm provided with is that "Apollo is said to be filled with grief: out of Hyacinthus' blood, Apollo created a flower named after him as a memorial to his death, and his tears stained the flower petals with the interjection αἰαῖ, meaning alas.". Is that enough to answer the question?
