The ancient Egyptians venerated the ibis. Followers of ibis cults would visit temples and purchase mummified ibises for use in votive offerings. The ibis was a sacred bird associated with creation and fertility and knowledge and learning. The ibis cults became so wildly popular that priests began breeding and rearing the birds onsite, specially for mummification.
Political theorist Hannah Arendt, in her 1963 book On Revolution, surmises that hypocrisy is the worst of all vices since it destroys integrity, the only thing that allows the individual to reclaim their incorruptible self: ‘Only crime and the criminal, it is true, confront us with the perplexity of radical evil, but only the hypocrite is rotten to the core.’
