What ideas does petrarch convey in these sonnets about the nature of beauty poetic inspiration and love at first sight?

In Petrarch's sonnet 90 regarding true love, he expresses the following ideas: his love for Laura - one of the characters - does not fade with time; age doesn't matter to him. And secondly, because she has not returned, loving her was so painful.

Francesco Petrarca (original Italian name), was born in Arezzo, Italy, in 1304.

By the year 1327, Petrarch fell in love with a girl named "Laureta", who was the inspiration for most of Francesco's poetry. Some author's question the existence of this woman, but she really influenced the emotions of the poet, reflecting his feelings in its sonnets.

Later in his life, Petrarch traveled through Europe, to meet with Dionigi da Borgo, who gave him a copy of the book Confessions, of Saint Agustine.
