What type of collection does Etarcomol and Medb have in common?
Medb Medb (pronounced ] )—later spelled Meadhbh (] ) and Méabh (] )—is queen of Connacht in the Ulster Cycle of Irish mythology. Her husband in the core stories of the cycle is Ailill mac Máta, although she had several husbands before him who were also kings of Connacht. She rules from Cruachan (now Rathcroghan, County Roscommon). She is the enemy (and former wife) of Conchobar mac Nessa, king of Ulster, and is best known for starting the "Táin Bó Cúailnge" ("The Cattle Raid of Cooley") to steal Ulster's prize stud bull. Medb is strong-willed, ambitious, cunning and promiscuous, and is an archetypal warrior queen. She is believed to be a manifestation of the sovereignty goddess. Medb of Connacht is probably identical with Medb Lethderg, the sovereignty goddess of Tara, and may also be linked with the Morrígan.
Methamphetamine Methamphetamine (contracted from "N"-methylamphetamine ) is a strong central nervous system (CNS) stimulant that is mainly used as a recreational drug and less commonly as a treatment for attention deficit hyperactivity disorder and obesity. Methamphetamine was discovered in 1893 and exists as two enantiomers: levo-methamphetamine and dextro-methamphetamine. "Methamphetamine" properly refers to a specific chemical, the racemic free base, which is an equal mixture of levomethamphetamine and dextromethamphetamine in their pure amine forms. It is rarely prescribed due to concerns involving human neurotoxicity and potential for recreational use as an aphrodisiac and euphoriant, among other concerns, as well as the availability of safer substitute drugs with comparable treatment efficacy. Dextromethamphetamine is a much stronger CNS stimulant than levomethamphetamine.
