"Doktor Faustus" (Marlowe):
»Was this the face that launched a thousand ships/
And burnt the topless towers of Ilium?«
" Troilus und Cressida" (Shakespeare):
»Why, she is a pearl,/
Whose price thath launch’d above a thousand ships,/
And turn’d crown’d kings to merchants.«
"The Iron Age" (Heywood)
…..this is the beauty,
»That launch’s a Thousand ships from Aulis gulfe
