Marcus Tullius Cicero,
Letters to Atticus — 13.10 (DCXXI)
“ To Atticus at Rome Tusculum, June 20 I am not at all surprised either at your sorrow in regard to Marcellus or at your misgiving as to increased sources of danger. For who would have feared such a thing as this --a thing that had never happened before and which nature seemed to forbid the possibility of happening? Therefore there is nothing that may not be feared. ”
