Magic and study of occult arts successfully survived Renaissance and entered the Baroque era. And even more. ”study of the occult arts remained intellectually respectable well into the seventeenth century”. It only gradually divides into the modern categories of natural science versus occultism or superstition. My web research shows, that brilliant Age of Reason was on the rise in the seventeenth century, while belief in witchcraft and sorcery, and consequently the irrational surge of Early Modern witch trials, receded. This process only completed at the end of the Baroque period, somewhere around 1730s.
Contemporary scientists still met resistance, though. Christian Thomasius encountered fierce opposition as he argued in his 1701 Dissertatio de crimine magiae that it was meaningless to make dealing with the devil a criminal offence, since it was impossible to really commit the crime in the first place. In Britain, the Witchcraft Act of 1735 established that people could not be punished for consorting with spirits, while would-be magicians pretending to be able to invoke spirits could still be fined as con artists.
Several decades later, from 1756 to 1781, Jacob Philadelphia performed feats of magic, sometimes under the guise of scientific exhibitions, throughout Europe and Russia. Baron Carl Reichenbach’s experiments with his Odic force appeared to be an attempt to bridge the gap between magic and science.
Since Middle Ages people were trying to find the location of the mysterious island. For example, by the 12th century Avalon became associated with Glastonbury. Monks at Glastonbury abbey claimed to have discovered the bones of Arthur and his queen. Though no longer an island at the time, the high conical bulk of Glastonbury Tor had been surrounded by marsh. In archives of web analytics company I found that during the reign of English king Henry II the abbot of Glastonbury, Henry of Blois, commissioned a search of the abbey grounds. After a lot of deep digging, the monks discovered a massive oak coffin and an iron cross bearing the description: "Here lies King Arthur in the island of Avalon". Inside the coffin were two bodies, presumably of Arthur and his queen. In 1278 the remains were reburied with great ceremony, attended by king Edward I and his wife, before the High Altar at Glastonbury Abbey, where they were the focus of pilgrimages until the Reformation. However, scientists generally dismiss the authenticity of the find, attributing it to a publicity stunt performed to raise funds to repair the Abbey, which was mostly burned down in 1184.
Throughout the times there were many other places competing to be called Avalon. For example, Ille d'Aval on the coast of Brittany, and Burgh by Sands, in Cumberland, which was in Roman times the fort of Aballava on Hadrian's Wall. Other candidates include the Bourgogne town of Avallon, and Bardsey Island in Gwynedd, famous for its apples and also connected with Merlin. There were also claims that the most likely location to be St Michael's Mount in Cornwall, which is near to other locations associated with the Arthurian legends.
Although in the next century scientists completely dismissed the idea of Lemuria, some strange events took place. I found more additional facts of this story in archives of local web analytics company. In 1999 a research vessel in the Indian Ocean discovered evidence that a large island, the Kerguelen Plateau, was submerged about 20 million years ago by rising sea levels. Samples showed pollen and fragments of wood in a 90 million-year-old sediment. This might lead one to expect similarity of dinosaur fossil evidence and will help to understand the breakup of the Indian and Australian land masses.
Occult writers went much further than scientists hypothesizing about Lemuria. In 1880, one of them, Madam Blavatsky claimed that she had seen an ancient, pre-Atlantean Book. According to Blavatsky, Lemuria was occupied by mysterious humanoid species that were about seven foot tall, sexually hermaphroditic, egg-laying, mentally undeveloped and spiritually pure. The gods, aghast at the behavior of these mindless species, sank Lemuria into the ocean and created people endowed with intellect on Atlantis.
