Lucretius, On the Nature of Things--
"Just as thou seest how motion will o'erheat /
And set ablaze all objects, - verily /
A leaden ball, hurtling through length of space, /
Even melts."
Virgil, The Aeneid, Book 9, Stanza LXXV – "His lance laid by, thrice whirling round his head /
The whistling thong, Mezentius took his aim. /
Clean through his temples hissed the molten lead, /
And prostrate in the dust, the gallant youth lay dead."
