Calyx-Krater by the artist called the Painter of the Berlin Hydria depicting an Amazonomachy Calyx-Krater by the artist called the Painter of the Berlin Hydria depicting an Amazonomachy The calyx-krater by the artist called the "Painter of the Berlin Hydria depicting an Amazonomachy" is an ancient Greek painted vase in the red figure style, now in the Metropolitan Museum of Art, New York. It is a krater, a bowl made for mixing wine and water, and specifically a calyx-krater, where the bowl resembles the calyx of a flower. Vessels such as these were often used at a symposion, which was an elite party for drinking. Warfare depicted in Greek art was often not representative
Discodermia calyx species, among others with similar toxins, became increasingly studied and important in medicine, particularly relating to chemotherapy. In a later study, scientist concluded that the calyculin A, from "D. calyx," also blocks calcium influx by blocking non-selective ion channels in the cell. Later research looked into "D. calyx" as a species to look at the natural mechanisms that can be used to regulate the toxicity of calyculin A. Scientist found regulation through phosphorylation and dephosphorylation. These among other studies focus on regulation of the toxin as a characteristic of the sponge Discodermia Calyx because of its implications in the fight
