There are several mapping between sets holding an equal number of entities. For the number 7, we have 7 days of the week, 7 gods, 7 celestial bodies and 7 metals.<\/p>\n\n\n\n\n\n\n\n\n\n\n
Days<\/strong><\/td>\nGods<\/strong><\/td>\nPlanets<\/em><\/strong><\/td>\nMetals<\/strong><\/td>\n<\/tr>\n

Saturday<\/td>\nSaturn<\/td>\nSaturn<\/td>\nLead<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

I use here the traditional ordering for the days of the week, starting on Sunday and ending on Saturday. This would give a first mapping to the number 1 to 7. But there exists another classical\u00a0pairing of these seven gods to the numbers 3 to 9, so called planetary numbers.<\/p>\n\n\n\n\n\n\n\n\n\n\n
Gods<\/strong><\/td>\nPlanetary Numbers<\/strong><\/td>\n<\/tr>\n
Saturn<\/td>\n3<\/td>\n<\/tr>\n
Jupiter<\/td>\n4<\/td>\n<\/tr>\n
Mars<\/td>\n5<\/td>\n<\/tr>\n
Sun<\/td>\n6<\/td>\n<\/tr>\n
Venus<\/td>\n7<\/td>\n<\/tr>\n
Mercury<\/td>\n8<\/td>\n<\/tr>\n
Moon<\/td>\n9<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

We will found more on this gods\/numbers association in the making of kamea<\/a>, or planetary talismans. For now, I just want to show what happens when we put back those gods\/numbers pairs in the order of their weekdays sequence.<\/p>\n\n\n\n\n\n\n\n\n\n\n
Days<\/strong><\/td>\nGods<\/strong><\/td>\nNumbers<\/strong><\/td>\n<\/tr>\n
Sunday<\/td>\nSun<\/td>\n6<\/td>\n<\/tr>\n
Monday<\/td>\nMoon<\/td>\n9<\/td>\n<\/tr>\n
Tuesday<\/td>\nMars<\/td>\n5<\/td>\n<\/tr>\n
Wednesday<\/td>\nMercury<\/td>\n8<\/td>\n<\/tr>\n
Thursday<\/td>\nJupiter<\/td>\n4<\/td>\n<\/tr>\n
Friday<\/td>\nVenus<\/td>\n7<\/td>\n<\/tr>\n
Saturday<\/td>\nSaturn<\/td>\n3<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

In this order, the planetary numbers decrease, starting from Monday\/9, every two days. Or they increase, starting from Saturday\/3, every 5 days.<\/p>\n

While today the number of days in the week remains 7, the number of known planets and the number of known metals have increased with the advance of science. Interestingly, new found planets and some metals have been named with the blessing of tradition, by selecting the name of one of the god from the roman pantheon. And of course, those three gods have fitting planetary numbers. If we put those celestial body in the order in which they occur in the solar system as we know it today, we get the following sequence.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
