An even more popular theory is that Greek traders brought coarse-haired setters to Italy during the height of the Roman empire, where the dogs were then crossed with various others and the modern Spinone eventually emerged. The French claim that the Spinone has descended from crosses of several French pointing breeds, whilst the Italians believe the Spinone is the ancestor of the Wirehaired Pointing Griffon, the German Wirehaired Pointer, and the Pudelpointer.

A-type main-sequence star also occasionally sees Delta Leonis (A4 V) listed as a standard. There are no published A6 V and A8 V standard stars. A-type stars are young (typically few hundred million years old) and many emit infrared (IR) radiation beyond what would be expected from the star alone. This IR excess is attributable to dust emission from a debris disk where planets form. Surveys indicate massive planets commonly form around A-type stars although these planets are difficult to detect using the Doppler spectroscopy method. This is because A-type stars typically rotate very quickly, which makes it difficult to measure the small
