Skill issue

If you do want to learn more, Innuendo Studios did a 6 part series called Why Are You So Angry? that’s pretty short (most episodes are ~10 minutes) but goes into the details

Edit: part 4 (An Autopsy of Gamergate, 18min) is probably the best summary, but the entire series is worth a watch if you have the time

TIL!

Various interpretations of the meaning of the picture have been offered: the conflict between youth and old age, time as the devourer of all things, the wrath of God and an allegory of the situation in Spain, where the fatherland consumed its children in wars and revolution. There have been explanations rooted in Goya’s relationships with his son, Javier, the only of his six children to survive to adulthood, or with his live-in housekeeper and possible mistress, Leocadia Weiss; the sex of the body being consumed cannot be determined with certainty. If Goya made any notes on the picture, they did not survive, as he never intended the picture for public exhibition.
