- Claudius Ptolemy (/ˈtɒləmi/; Greek: Πτολεμαῖος, Ptolemaios; Latin: Claudius Ptolemaeus; c. 100 – c. 170 AD) was a Roman mathematician, astronomer, astrologer, geographer, and music theorist, who wrote about a dozen scientific treatises, three of which were of importance to later Byzantine, Islamic, and Western European science. The first is the astronomical treatise now known as the Almagest, although it was originally entitled the Mathēmatikē Syntaxis or Mathematical Treatise, and later known as The Greatest Treatise. The second is the Geography, which is a thorough discussion on maps and the geographic knowledge of the Greco-Roman world. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day. This is sometimes known as the Apotelesmatika (lit. “On the Effects”) but more commonly known as the Tetrábiblos, from the Koine Greek meaning “Four Books”, or by its Latin equivalent Quadripartite.
- Seattle Neighborhoods: Mount Baker — Thumbnail History (historylink.org)
Seattle’s Mount Baker community lies on Lake Washington southeast of downtown between the Leschi and Lakewood/Seward Park neighborhoods. This gentle hump above the lake, with views of the Cascade Range to the east and north across the lake and of the Rainier Valley and the Olympic Mountains to the west, is named for the North Cascades volcano whose 10,788-foot-high snow-covered dome dominates the distant northeast view.
