ザテトラーク
He was sired by The Tetrarch an unbeaten horse who was regarded as one of the fastest two-year-olds ever seen in Britain and Ireland, but whose career was ended by injury before he could race at three. The Tetrarch showed very little interest in his stud duties (his attitude towards sex was described as being "monastic in the extreme") and as a result sired few foals. Tetratema's performances enabled The Tetrarch to win his only sires' championship in 1919. Tetratema's dam Scotch Gift won the Somerville Stakes at Newmarket and became a successful broodmare: her other foals included Tetratema's full-brothers The Satrap, a very fast colt who won the July Stakes and Richmond Stakes in 1926, and Arch Gift a sprinter whose wins included the Bretby Stakes.
