Who was the primary subject of the 300 sonnets and 49 canzoni songs in Petrarch's Canzoniere Songbook?

Petrarch's love poetry is mainly addressed to a woman he saw at church on Good Friday 1327, whom Petrarch calls 'Laura' and who may have been Laura de Noves.

But it is misleading to say that Laura is the primary subject of the sonnets and canzoni: Petrarch says very little about the woman herself.

Petrarch is mainly interested in what 'being in love' feels like; so although the sonnets seem to be addressed to 'Laura' Petrarch is really talking mainly about himself.

Talking about a real woman in a Sonnet pretty much had to wait for Edmund Spenser - who allows the girl to talk in her own person in his 'One Day I Wrote Her Name Upon The Strand - and didn't really get off the ground until Juliet gets to share a sonnet with Romeo in Shakespeare's play.
