They did remove the heart, but also had skull racks, and gave the bodies to the people for meat. Somewhere I saw a drawing of a skull rack with a large number of skulls on it. I don’t know if it was a codex or something Spanish. When I studies in Mexico, I read concurrently Cortez’s 5 Letters to King Carlos V, and Bernal Diaz’ (his lieutenant) account of the conquest both in Spanish. Very interesting and very bloody.
