De coitu (Constantinus Africanus)
De coitu est opus mediaevale Latine scriptum de sexualitate, de morbis sexualibus, et de medicamentis aphrodisiacis. Constantinus Africanus, auctor medicus et professor Salernitanus origine Carthaginiensis, eum librum saeculo IX composuit vel potius e lingua Arabica convertit; quem in carmine suo Canterbury Tales Galfridus Chaucer sic citat, senem quemdam Ianuarium illudens: ... This hastif Januarie Wolde go to bedde; he wolde no lenger tarye. He drynketh ypocras, clarree, and vernage Of spices hoote t'encreessen his corage; And many a letuarie hath he ful fyn, Swiche as the cursed monk, daun Constantyn, Hath writen in his book De Coitu. – Chaucer, Canterbury Tales, "The Merchant's Tale" Hic Ianuarius ad cubiculum ire festinans, morae impatiens, bibit hippocratem, claretum, vernacium omnia aromatibus calida ut virtutem fortificet, multaque electuaria tenet optima sicut monachus Constantinus nefandus in libro suo De coitu descripsit. ― convertit Vicipaedia
