Since the first 12 elements (carbon (6), sulfur (16), iron (26), copper (29), zinc (30), arsenic (33), silver (47), tin (50), antimony (51), gold (79), mercury (80), and lead (82)) are "ancient" (and hence the exact order of their discovery is vague), they have been omitted. The list starts with the first actual date that is given, which is 1669.
