Cornelius delivered 7 coloured mares of which RETINA, with 4 daughters, was most successful. Two of them, RECESJA and RETORTA brought four graded colored stallions, all of them pure bred Trakehners, REWIR, REWANZ, RECITAL (by Recesja) and RESOR (by Retorta). Most of the Polish coloured horses that can be considered Trakehner, have one of these stallions in their pedigree. In particular Rewir (with his best son NIL) has dominated Polands colourbreeding for a long time and his offspring in the meantime can be found all over Europe, like the well known pure bred coloured Trakehner MAKAR whose offspring has good chances to get approval by the Trakehner Verband, three of his daughters already received registration.
