Although it appears that the husband was sexually jealous of the Duchess within the poem, alternatively, it could be argued that he was not. The quote "it was not her husband's presence only" whilst "Fra Pandolf" was painting her, suggests that there was no reason to believe that the Duchess could have had an affair - as the Duke was apparently present. Furthermore, Browning's audience would have recognised that the name "Fra" is short for friar - who is a monk. This meant that, despite him being a painter, he was also a monk, and would therefore not have had an affair, giving the Duke no reason to be sexually jealous. Alternatively, the author could be suggesting that if the Duke was sexually jealous, it is an absurd emotion to have, given that the "Fra" was a monk, and could have, in no way, had a sexual relationship with the Duchess.
