There's good archeological evidence that the Carthaginians really sacrificed their own children.
From The Guardian:
Just as ancient Greek and Roman propagandists insisted, the Carthaginians did kill their own infant children, burying them with sacrificed animals and ritual inscriptions in special cemeteries to give thanks for favours from the gods, according to a new study.
"This is something dismissed as black propaganda because in modern times people just didn't want to believe it," said Josephine Quinn, a lecturer in ancient history at Oxford, who is behind the study, with international colleagues, of one of the most bitterly debated questions in classical archaeology.
"But when you pull together all the evidence – archaeological, epigraphic and literary – it is overwhelming and, we believe, conclusive: they did kill their children, and on the evidence of the inscriptions, not just as an offering for future favours but fulfilling a promise that had already been made.
"This was not a common event, and it must have been among an elite because cremation was very expensive, and so was the ritual of burial. It may even have been seen as a philanthropic act for the good of the whole community."
Argument has raged on the subject since cemeteries known as tophets – after the biblical account of a place of sacrifice – were excavated in the early 20th century on the outskirts of Carthage in modern Tunisia, and then at other Carthaginian sites in Sicily and Sardinia. The graves held tiny cremated bones carefully packed into urns, buried under tombstones giving thanks to the gods...
Roman historian Diodorus and other ancient historians gave graphic accounts of Carthaginian child sacrifice: "There was in their city a bronze image of Cronus, extending its hands, palms up and sloping towards the ground, so that each of the children when placed thereon rolled down and fell into a sort of gaping pit filled with fire."The archeologists noted that many of their colleagues had trouble believing that child sacrifice really happened:
Quinn said many of her academic colleagues were appalled by her conclusions.
"The feeling that some ultimate taboo is being broken is very strong. It was striking how often colleagues, when they asked what I was working on, reacted in horror and said, 'Oh no, that's simply not possible, you must have got it wrong.'"On a related topic, we recently passed the forty-first anniversary of Roe v. Wade. Fifty five million children have been aborted in our country since 1973. Four thousand children are aborted each day in America. Their bones can be found not in urns at archeological digs but in incinerated medical waste.
Nearly all of them are sacrificed to the idol of personal fulfillment.
"We like to think that we're quite close to the ancient world, that they were really just like us – the truth is, I'm afraid, that they really weren't."The Carthaginians were not like us.
They would be appalled by the callousness and scale of our child sacrifice.
