Dinas Dinllev is the place where Gwydion brought up Llew Llaw Gyffes, guiding him until he could manage a horse and had become remarkable in features, strength, and stature. The brief reference makes the location significant as a setting for Llew’s upbringing and the transition from his youth toward action beyond it.

Setting and Upbringing

The narrative places Gwydion and Llew at Dinas Dinllev after they have gone there. Gwydion raises the youth at this location until Llew can manage a horse, establishing a concrete measure of his growing capability. The account also presents him as having attained impressive features, strength, and stature.

From Upbringing to Expedition

After observing that Llew languishes for want of horses and arms, Gwydion calls him to join an errand the following day and urges him to be more cheerful. Llew agrees. The passage thus connects the place where Gwydion has brought him up with a shift in their relationship: Gwydion’s care gives way to a shared undertaking, and Llew is poised to enter the wider action.
