Note 323 — Chapter V · THE SUMMONS TO ROME.
G. (George) Sturge translation
It is incomprehensible how many of Galileo’s biographers, even Parchappe (p. 216) and H. Martin (p. 120), who had Albèri’s work at command, fix the 15th as the date. And yet we have a letter of Galileo’s to the Cardinal de Medici of the 15th Jan. (Op. vii. pp. 15, 16), asking if he had any commissions, in which he expressly mentions “the 20th instant” as the day of his departure.
