 At the age of fifteen he published a poem on the silkworm, "Bombace e Seta" (Rome, 1624).Two years later, emulous of the reputation Marino had just gained with his "Adone", the young Argoli is said to have shut himself in an apartment, where he was visited only by servants bringing his food, and in seven months, at the age of seventeen, produced his "Endimione" (Rome, 1626).It met with a success apparently at least equal to the author's hopes.
