In Aeneid Book X, there is a strong idea that ‘fathers have a duty to protect their children.’ To what extent do you agree?

Perhaps the first father-son relationship that comes to mind when considering the Aeneid is that of Ascanius and Aeneas, in spite of the fact that for much of this Book, the two are separated, with Ascanius’ camp encircled by Rutulian forces, and Aeneas sailing back in from Pallantium. However, when the sea-nymphs appear to Aeneas towards the start of this book, born of the sacred wood of Mount Ida from the destroyed ships, and warn him of the danger his son and his people face, he makes no hesitation in running his ships ashore, to defeat the Rutulians and reach his son with reinforcements. In this sense we can indeed see that Aeneas, especially as he is a particularly pious character, feels that he has a duty to protect his son, and he acts on this as soon as he realises his son is in danger.
