Metui demens credebat honorem. - Silius Italicus

The higher they climbed in their struggle to reach the top, the harder grew their toil. When one height had been mastered, a second opens and springs up before their aching sight.

Postquam oculos varia implevit virtutis imago,
mira dehinc cernit: surgentis mole profundi
injectum terris subitum mare nullaque circa
litora et infuso stagnantis aequore campos.
nam qua caeruleis Nereus evoluitur antris
atque imo freta contorquet Neptunia fundo, proruptum exundat pelagus, caecosque relaxans
Oceanus fontis torrentibus ingruit undis.
tum uada, ceu saevo penitus permota tridenti,
luctantur terris tumefactum imponere pontum.
mox remeat gurges tractoque relabitur aestu,
ac ratis erepto campis deserta profundo,
et fusi transtris expectant aequora nautae.
Cymothoes ea regna vagae pelagique labores
Luna mouet, Luna, immissis per caerula bigis,
fertque refertque fretum, sequiturque reciproca Tethys.

Pax optima rerum
quas homini novisse datum est, pax una triumphis
innumeris potior, pax custodire salutem
et civis aequare potens revocetur in arcis
tandem Sidonias, et fama fugetur ab urbe
perfidiae, Phoenissa, tua.
