Cassini named the four new moons as "Sidera Lodoicea" ("the stars of Louis") to honour king Louis XIV of France. By the end of the seventeenth century, astronomers fell into the habit of referring to them and Titan as "Saturn I" through "Saturn V" (Tethys, Dione, Rhea, Titan, Iapetus). Once Mimas and Enceladus were discovered in 1789 by William Herschel, the numbering scheme was extended to "Saturn VII" by bumping the older five moons up two slots. The discovery of Hyperion in 1848 changed the numbers one last time, bumping Iapetus up to "Saturn VIII". Henceforth, the numbering scheme would remain fixed.
