In early days pursuing The Thoroughbred interests, there went forum outcries to the Phalaris disease. https://www.pedigreequery.com/forum/viewtopic.php?t=11081, phalaris lines spell speed at the expense of soundness
Obviously, Phalaris male line made hay…(Nearco)
From insight the remarkable threshold, the male line at grand-father Cyllene is unbelievably staggering. Getting my hands to 1960 New Zealand stallion registries, the spell-binding breeding significance of Cyllene descendants was and is still not to be missed. His lines are seriously present.
Cyllene – Captivation sire of Kircubbin sire of Chateau Bouscaut sire of *The Phoenix & Chanteur
Cyllene sire of Cylgad, sire of Kassala, sire of Pappageno II
Cyllene sire of Bridge of Earn, sire of Bridgemount sire of Foxbridge
Cyllene sire of Polymelus
Cyllene sire of Cicero, sire of Friar Marcus
Cyllene sire of Lemberg
Cyllene sire of Helicon
Cyllene sire of Cellini
Cyllene sire of Minoru, sire of daughter Serenissima dam of SELENE
Phalaris – Pharos sire of Firdaussi
Fairway, sire of Fair Trial: his full brother Pharos sire of Nearco
By references (three stallion registers) 
what was apparent, then the major influences, to line @Teddy, the strain @ Carbine descendants (Spearmint) and with Hyperion from his dam @Selene (further to her sire-son influences Sickle, Pharamond, Hunter’s Moon )to another @ Bay Ronald’s line through son Dark Ronald & his son Gainsborough.
At tail-male Cyllene to a Teddy cross was ‘pre-present’ to Argentina genetic-giant British Empire (GB) 1937. He was bred by Lord Glanely and sent to Argentina 1940. He won four races as a 2 year old. The Teddy daughter Rose of England won the Oaks. His son Equinox (ARG) cross broodmare sire is Hunter’s Moon (Selene), further distaff influence Carbine (Clemence) +2×3 Hampton by Lord Clifden ex The Slave, Martha Lynn.
The Teddy male-line with Spearmint cross (daughter Plucky Leige) produced Bull Dog (FR) 1927 & Sir Gallahad (FR). Half-Brother Admiral Drake (FR) by Craig an Eran (GB) has broodmare sire Cyllene.
The ‘link’ between Teddy and Cyllene is Bend Or/Tadcaster back to distaff Clemence/Martha Lynn family assigned family 2-h. The Bay Ronald link and tail-line to these superior individuals is back to The Slave distaff of Martha Lynn. (n.b. whilst Martha Lynn families has L4 haplotype, I suspect the predecessor was also part G Haplotype – a formative cross sub-variant type to many Horse breeds.
An Australian Hall of Fame chestnut Heroic was the leading sire in Australian 7 times in succession. Heroic’s racing record speaks for itself – 1st: AJC Champagne S., AJC Derby, VATC Caulfield Guineas, VATC Caulfield S., MVRC W.S. Cox Plate, VRC Newmarket H., WmtnRC Underwood S., AJC Breeders’ Plate, VRC Maribyrnong Plate, Tatt’s NSW Chelmsford S., VRC Ascot Vale (2yo) S., AJC Autumn S., VATC Memsie S. (x2), AJC Cumberland S., MVRC William Reid S., VATC St. George S., VRC King’s Plate, WmtnRC C.F. Orr S.
Remarkably Heroic has 3Sx3 Cyllene, 3x Hampton by Lord Clifden from The Slave/Martha distaff + 4x Bend Or/Tadcaster as prior mentioned. https://www.pedigreequery.com/heroic
TBL favourite character Court Martial (Fair Trial) by @Winkiepop distaff many a time profiles to Australian bred – do note Court Martial has >> 5×5 Cyllene + 5×5 Bay Ronald.
Re-evaluation upon Cyllene – Bay Ronald and affinities Teddy & Selene goes central. Our antipodean great sire Sir Tristram (Sir Ivor) tail-male Polymelus/Cyllene – 2x Princequillo >Minoru/Cyllene + Bayardo/Bay Ronald + Selene distaff. Sir Tristram’s best son Zabeel from Lady Giselle 2x Hyperion/Selene + 3×4 Sunny Boy > Teddy, 3x Bay Ronald + distaff Friar Marcus/Cicero/Cyllene.
What’s the Nutshell?
Since research here has of late, explores G haplotype in connection of formatting superior Types it is pretty much conclusive what the superior, bred Elite direction is. However, hooking into G Haplotype prepare to be befuddled at Ped. Tables, with literature side-stepping the greater picture; a hybrid-Thoroughbred framework as alone Northern European British bloodstock recorded goes clearly not that simple.
What we need to realize and exploit where probability arises….its pretty obvious by now why, to the Galileo potency. There are more…
As much taken by this sire Isfahan (Ger) https://www.ohlerweiherhof.de/deckhengste/deckhengst_isfahan.php the key-markers are reasonably evident. Leading Juvenile sire in England, among the leading Broodmare Sires in N.A. — Sire of 83+ SW and 10 Champions – headlines 4×4 Sharpen Up, himself of the Sickle/Selene tail-male 5×3 Hyperion/Selene + Carbine (fam.2-h) thru Felstead & Bois Roussel, sire Atan distaff 3rd dam by Fairway, Fair Play through Discovery, Rocchetta’s 4th dam by Pharos. The ‘band’ of ‘G’ genetic Players are all to see viz. Bay Ronald/Dark Ronald ie Birkhahn (Ger), Sickle (particularly Sea Bird),
In an era when we rarely concern ourselves with names beyond the fifth generation, we hardly ever encounter Cyllene. He is further back in pedigrees, and it is no exaggeration to state in all pedigrees. His Derby winners played their part, but the star turn was unquestionably Polymelus, five times champion at stud and sire of Phalaris, the most influential of all 20th century stallions. by Tony Morris https://www.thoroughbredracing.com/articles/3714/tony-morriss-100-shapers-breed-sire-who-became-staple-ingredient/
Cyllene a symmetrical chestnut colt, inherited a wonderful temperament. Cyllene sired four English Derby winners in 1909 and 1910 and also led the Sires List in Argentina. He was a horse that could accelerate more than once during a race and he was able to pass this gift to many of his progeny, especially to his tall son Polymelus. Ken McLean – Quest for a Winner
Cyllene never stops… to be one of the most penetrative potent influences ever and to end this dissertation (its never completed) the most important dam-line to sires in making is designated Reine-de-Course mare Striking (family 1-x). https://www.pedigreequery.com/striking To be Noted, Fair Play – Spearmint – Teddy – Cyllene
