Cf. Van der Lugt Pourquoi Dieu At the turn of the thirteenth and the fourteenth century, an important period for anthropological thinking among theologians, there is a small but significant vogue for questions about siamese twins. Nicholas of Lyra's choice to replace the hermaphrodite by siamese twins would seem to reflect these developments in theology. Like other limiting cases such as the embryo or the corpse, siamese twins served as models to define the complex relationship between soul and body, form and matter. See Van der Lugt, " L'humanité des monstres Homme ou femme? Les juristes musulmans face à l'hermaphrodisme Summa de sacramentis et anima consiliis, III, 2a, cap. xvii (ed. cit., 259) Emergency baptism during childbirth is possible as soon as the head, or another part of the child's body can be seen. 40. The author of the Summa 'Omnes homines' bases the preference for a male name on the supposed natural superiority of the male, an explanation typical of the misogynous tendencies of the collection: " . . . responditur quod nomine viri. Ratio est quia nomina imponuntur ad placitum et secundum nomen dignius debet baptizari, quia omnis vir dignior est muliere, quia omne agens prestantius est suo passo Hermaphroditus an ad testamentum adhiberi possit, qualitas sexus incalescentis ostendit, Monstre et imaginaire social, 163?86. 39.

Glossa ordinaria, C. IV, q. 2 et 3, canon 3, par Quaesitum fuit utrum hermaphroditus, idest qui habet sexum maris et feminae, possit esse testis in testamento Sed quid si in omnibus est parilitas? Item numquid talis potest ordinari ? Item an contrahet cum viro, an cum muliere, et si prius cum viro contraxit, an possit eo mortuo cum muliere contrahere? Io<hannes Teutonicus>. Sed certe in omnibus his respici debet sexus qui magis incalescit. De monstro possunt fieri monstruosae quaestiones . Hug<uccio>, Huguccio's remark admittedly also refers to ordination, and possibly testifying, but the fact that mariage and remariage appear as the last item, and are described in more detail suggests that this was, indeed, the case that provoked Huguccio's remark, pp.97-98, 0713.
