The Pendulum of Life

Nec, quae praeteriit, iterum revocabitur unda:
Nec, quae praeteriit, hora redire potest.
Ovidius Naso, Ars Amatoria, Lib. iii

The moon rises, the sun falls
The twilight darkens, the librarian calls
    From the reading room quiet and warm
    The poet hastens towards his dorm
Walking through these Gothic halls

Darkness devours the dusk of day
Lamps on the road are dim and gray
    And his heart, drowsy, tired and dull
    Wandering like an aimless gull
Has nothing but silence to say

The morning breaks, the alarm calls
And the dreamful silence stalls
    The day returns, but nevermore
    Returns the days with her before
And the moon rises and the sun falls

Nec…potest (Latin): Neither will the wave
which has passed be called back;
nor can the hour which has gone by return.
