We also know that, at least amongst the Gaulish and the early medieval Irish nobility, polygyny was a widespread practice. Given the detail given to different kinds of sexual union in early medieval Welsh law, it seems reasonable to assume that polygyny was also common in Wales some time before the law-texts were put into writing. Given that the main focus in the early medieval Irish laws where sexual unions are concerned are with the contribution to and division of assets of the union in case of divorce, as well as the responsibilities towards children resulting from these unions, it is quite likely that similar provisions also were at the core of earlier Celtic laws' treatments of the matter of sexual unions. This also seems to correspond with the significance attributed to the equal contribution of assets by Caesar, while the fact that he assumes that the man would have owned more property than contributed by the wife would fit well with the possibility of several different kinds of recognised sexual unions, some with greater, some with lesser or no contributions by the female partner.
