Cassini II, the younger full brother of Cassini I, was approved in Holstein in 1996 with a high jumping index. Unfortunately he was injured when young and did not compete in sport although is now sought after as a sire due to his quality and talented offspring. At his Licensing he achieved high scores for his jumping as well as for his character and temperament. Cassini I & II are sons of the great Capitol I. Capitol I was on the top of the WBFSH (World Breeding Federation for Sport Horses) rankings lists 2000-2001. There are over 25 approved stallions by Capitol in Holstein. Worldwide there are many more approved sons and in Germany alone there are 564 registered sport horses which have won in excess of €5.3 million in prizemoney. Capitol I was a valuable foundation sire in the Holstein stud book.

Cassini II's dam Wisma is by Caletto II who was awarded Champion of his year when he was licensed in Holstein. Caletto II, one of the best sons of Cor de la Bryere has been a significant influence in jumping breeding even though he only stood for 4 years. He is the sire of Classic Touch who took Luger Beerbaum to win gold at the Barcelona Olympics. Wisma also produced the young Holsteiner Verband stallion Clarimo (by Clearway) along with a full sister to Cassini I & II who has produced the licensed stallion Lovari (by Lasino). Another daughter of Wisma, Mira (by Lansing) is the dam of the licensed stallion Cassaro.
