The portal of portals

Portal

A portal is an opening in the walls of a building, gate or fortification, and especially a grand entrance to an important structure. Doors, metal gates or portcullis in the opening can be used to control entry or exit. The surface surrounding the opening may be made of simple building materials or decorated with ornamentation. Elements of a portal can include the voussoir, tympanum, an ornamented mullion or trumeau between doors, and columns with carvings of saints in the westwork of a church.

Portals in science fiction allow rapid travel between distant locations, often originating from some combination of natural phenomenon and technological device. These fictional devices are required for most stories on an inter-solar scale, otherwise transit time would be excessive for storytelling purposes. An advantage of portal technology over a faster-than-light drive is that it can be imagined to work instantly, and can travel to the past or future. In other forms of fiction, a portal may be magical, and connect to an alternate universe or plane of existence.

Selected biography

Antoine Portal

Baron Antoine Portal (January 5, 1742-July 23, 1832) was a French anatomist, doctor, medical historian and founding president of the Académie Nationale de Médecine. Born in Gaillac, he was the eldest among 12 siblings. He studied medicine in Albi, Toulouse and Montpellier and started his career as a teacher of anatomy.

In 1766, Portal moved to Paris to take up a similar post, and was appointed to the prestigious position of professor of anatomy to the Jardin du Roi. Louis XVIII named him the first Doctor to the King, a post he also served in under Charles X. His close relationship with King Louis led in 1820 to the creation of what became the Académie Nationale de Médecine, of which he was lifelong president.

In 1803 Portal published "Cours d'anatomie médicale", a 5-volume work on medical history. He was probably the first to describe amyloid in liver in 1789 when he noted a lard-like substance in an elderly woman's liver, and the first to describe bleeding due to esophageal varices. He also published article on clinical features of epilepsy.

Portal died in 1832 at the age of 90 and was buried in Saint Pierre de Montmartre.

The movie's curse! Watching it opened a portal into another dimension!
The monster came through the portal, now it's going to hunt us down and eat us!
And I'm probably delicious!
