Sphragis-a signet; by implication the stamp impressed (as a mark of privacy, or genuineness) on a book or document or scroll :- a seal. Strong’s Talking Greek & Hebrew Dictionary.

In the first century, when Revelation was written, a person of authority would seal important documents to keep them secret or to authenticate them. Roman law required a last will and testament to be sealed 7 times, as the wills of Caesar Augustus and Emperor Vespasian were. This scroll with 7 seals, appears to be the last will and testament of Jesus, the Messiah.

Pyrrhus: from <G4442> (pur); fire-like, i.e. (special) flame-colored :- red. (or red like blood)
Strong’s Talking Greek & Hebrew Dictionary.

Pyrrhus in Greek mythology: Named Neoptolemus, but called “Pyrrhus” for his fiery hair, he was the son of Achilles and the princess Deidameia[1]. Pyrrhus is a sadistic perversion of his father’s legacy, heir to his strength and capacity for violence, but not his humanity. When he gets to Troy, Pyrrhus takes his father’s place as one of the most terrifying and reckless warriors of the Greeks.  He is among those in the Trojan Horse, and according to the Odyssey, the only one who isn’t afraid of being caught.  Once inside the city of Troy, he uses an ax to tear his way into Priam’s palace, leaving a bloody trail behind him.[2] From the book:

“He is the one who kills Priam. He is the one who hunts down Hector’s wife, Andromache, hiding in a cellar with her son. He plucks the child from her arms and dashes his head against the stone of the walls, so hard the skull shatters like a rotted fruit. Even Agamemnon blanched when he heard” ^[1]. From The Song of Achilles.

Pyrrhus of Epirus was a Greek king who reigned from 306 to 272 BC and is best known for his military campaigns against Rome, which led to the term “Pyrrhic victory,” referring to a win that comes at such a significant cost that it is almost tantamount to defeat. He was considered one of the greatest generals of his time, often compared to Alexander the Great for his military prowess and charisma.
