This Depiction is from a famous triptych painted by Hieronymus Bosch in either 1503 or 1504. The painting is called The Garden of Earthly Delights. This detail is cropped from the online version at Museo Nacional del Prado.
The threat of Hell was so important to christianity that there are many depictions of the horrible punishments and tortures that supposedly happen in hell. Obviously, the christian that painted this triptych didn't think that Hell is just a separation from God. To him Hell was a bizarre and terrible place that was to be avoided at all costs and that God actively consigns souls to horrible punishments like what is depicted here, forever.
