History of the star: A star in the River Eridanus. Rana is a Latin word for the genus "bullfrog"; so called because of its strong croak, said to sound like a bull bellowing.

[Star Names, Their Lore and Meaning, Richard Hinchley Allen, 1889]. 

The astrological influences of the constellation: According to Ptolemy all the stars with the exception of Achernar are like Saturn. Eridanus gives a love of knowledge and science, much travel and many changes, a position of authority, but danger of accidents, especially at sea and of drowning. (Fixed Stars and Constellations in Astrology, Vivian E. Robson, 1923).
