A work entitled Glaucus also belonged to Callimachus [25] (it is unclear though which Glaucus was its subject). The Roman author Velleius Paterculus made mention of Plancus, who performed in the role of Glaucus at a feast. [26] Scylla et Glaucus, an opera by Jean-Marie Leclair, was based on the myth of Glaucus's love for Scylla recorded in Ovid.
Scylla et Glaucus (Scylla and Glaucus) is a tragédie en musique with a prologue and five acts, the only surviving full-length opera by Jean-Marie Leclair. The French-language libretto by d'Albaret is based on Ovid's Metamorphoses, books 10, 13 and 14. It was first performed at the Académie Royale de Musique in Paris on 4 October 1746. [1]
Glaucus and Scylla by Bartholomeus Spranger (c. 1581) According to Ovid, [23] the fisherman-turned-sea god Glaucus falls in love with the beautiful Scylla, but she is repulsed by his piscine form and flees to a promontory where he cannot follow. When Glaucus goes to Circe to request a love potion that will win Scylla's affections, the ...
Antonie van Leeuwenhoek (1632–1723). The field of microscopy (optical microscopy) dates back to at least the 17th-century.Earlier microscopes, single lens magnifying glasses with limited magnification, date at least as far back as the wide spread use of lenses in eyeglasses in the 13th century [2] but more advanced compound microscopes first appeared in Europe around 1620 [3] [4] The ...
Two Leica oil immersion microscope objective lenses; left 100×, right 40×. The objective lens of a microscope is the one at the bottom near the sample. At its simplest, it is a very high-powered magnifying glass, with very short focal length. This is brought very close to the specimen being examined so that the light from the specimen comes ...
The focus of the first lens is traditionally about 2mm away from the plane face coinciding with the sample plane. A pinhole cap can be used to align the optical axis of the condenser with that of the microscope. The Abbe condenser is still the basis for most modern light microscope condenser designs, even though its optical performance is poor.
A bright-field microscope has many important parts including; the condenser, the objective lens, the ocular lens, the diaphragm, and the aperture. Some other pieces of the microscope that are commonly known are the arm, the head, the illuminator, the base, the stage, the adjusters, and the brightness adjuster.
Glaucous (from Latin glaucus, from Ancient Greek γλαυκός (glaukós) 'blue-green, blue-grey') is used to describe the pale grey or bluish-green appearance of the surfaces of some plants, as well as in the names of birds, such as the glaucous gull (Larus hyperboreus), glaucous-winged gull (Larus glaucescens), glaucous macaw (Anodorhynchus glaucus), and glaucous tanager (Thraupis glaucocolpa).
