La notte di San Lorenzo è tradizionalmente associata al fenomeno delle stelle cadenti, considerate evocative dei carboni ardenti su cui il santo fu martirizzato. In effetti, in quei giorni, la terra attraversa lo sciame meteorico delle Perseidi e l'atmosfera è animata da un elevato numero di piccole meteore.
Il fenomeno risulta particolarmente visibile alle nostre latitudini in quanto il cielo estivo è spesso sereno. Tra storia ed astronomia, guarderemo al cielo sopra di noi.
