respice item quam nil ad nos ante acta vetustas temporis aeterni fuerit,
quam nascimur ante.
hoc igitur speculum nobis natura futuri temporis exponit post mortem denique nostram.
numquid ibi horribile apparet?
num triste videtur quicquam?
non omni somno securius exstat?
(Lucretius, De rerum natura)
Look back also and see how the ages of everlasting time past before we were born have been to us nothing. This therefore is a mirror which nature holds up to us, showing the time to come after we at length shall die. Is there anything horrible in that? Is there anything gloomy? Is it not more peaceful than any sleep?
