Ulm, Marignon, Tien Chi, Jomon. Probably Man (closer to 15th centry, but I don't remember when pike/musket system actually became prevalent in England. Two-handed swords of wardens are surely Rennaisance thing). Bogarus is behind, but Russia was somewhat lagging back at that historical period, too... Also, remember that actual civilizations on which Mictlan is based flourished in 15th-16th century - they just looked archaic. And, of course, Cthulhu mythos on which R'lyeh is based appeared only at the beginning of 20th century!
