- Lysergic acid diethylamide (Wikipedia)
Lysergic acid diethylamide, commonly known as LSD (from German Lysergsäure-diethylamid), and known colloquially as acid or lucy is a potent psychedelic drug. Effects typically include intensified thoughts, emotions, and sensory perception. At sufficiently high dosages LSD manifests primarily mental, visual, and auditory hallucinations. Dilated pupils, increased blood pressure, and increased body temperature are typical. Effects typically begin within half an hour and can last for up to 20 hours (although on average, experiences last 8–12 hours). LSD is also capable of causing mystical experiences and ego dissolution. It is used mainly as a recreational drug or for spiritual reasons. LSD is both the prototypical psychedelic and one of the “classical” psychedelics, being the psychedelic with the greatest scientific and cultural significance. LSD is synthesized as a solid compound, typically in the form of a powder or a crystalline material. This solid LSD is then dissolved in a liquid solvent, such as ethanol or distilled water, to create a solution. The liquid serves as a carrier for the LSD, allowing for accurate dosage and administration onto small pieces of blotter paper called tabs. LSD is typically either swallowed or held under the tongue.

Cepheus was the mythological king of Ethiopia. He was deemed worthy of a place in the sky because he was fourth in descent from the nymph Io, one of the loves of Zeus – and having Zeus as a relative was always an advantage when it came to being commemorated among the constellations. The kingdom of Cepheus was not the Ethiopia we know today, but stretched from the south-eastern shore of the Mediterranean southwards to the Red Sea, an area that contains parts of the modern Israel, Jordan, and Egypt. Ptolemy described him as wearing the tiara-like head-dress of a Persian king, as he is shown on John Flamsteed’s star atlas…
