quid est quod fuit ipsum quod futurum est quid est quod factum est ipsum quod fiendum est nihil sub sole novum nec valet quisquam dicere ecce hoc recens est iam enim praecessit in saeculis quae fuerunt ante nos.
Or, in more colloquial english:
Everything that happens has happened before; nothing is new, nothing under the sun.
Someone might say, “Here is something new!” But it happened before, long before we were born.
