An anonymous chronicler writing during the civil wars of the 1320s, wrote that:

...upon looking on him [Piers Gaveston] the son of the king immediately felt such love for him that he entered into a covenant of constancy, and bound himself with him before all other mortals with a bond of indissoluble love, firmly drawn up and fastened with a knot.

The modern judgement on this by Edward's biographer J. R. S. Phillips is that:

Such comments have led to the modern assumption that their relationship was definitely sexual. The evidence for this, however, is far from clear. While some of the chroniclers' remarks about Edward II can be interpreted as implying homosexuality or bisexuality, too many of them are either much later in date or the product of hostility, or a combination of the two, and thus not acceptable at face value.
