In Greek mythology, Eros (/ˈɪərɒs/ or US /ˈɛrɒs/, /ˈɛroʊs/;Greek: Ἔρως, "Desire") was the Greek god of love. His Roman counterpart was Cupid ("desire"). Some myths make him a primordial god, while in other myths, he is the son of Aphrodite. He was one of the winged love gods, Erotes.

Cult and depiction

Eros appears in ancient Greek sources under several different guises. In the earliest sources (the cosmogonies, the earliest philosophers, and texts referring to the mystery religions), he is one of the primordial gods involved in the coming into being of the cosmos. But in later sources, Eros is represented as the son of Aphrodite, whose mischievous interventions in the affairs of gods and mortals cause bonds of love to form, often illicitly. Ultimately, in the later satirical poets, he is represented as a blindfolded child, the precursor to the chubby Renaissance Cupid, whereas in early Greek poetry and art, Eros was depicted as an adult male who embodies sexual power, and a profound artist.

EROS (The Extremely Reliable Operating System) is an operating system developed beginning in 1991 by The EROS Group, LLC., the Johns Hopkins University, and the University of Pennsylvania. Features include automatic data and process persistence, some preliminary real-time support, and capability-based security. EROS is purely a research operating system, and was never deployed in real world use. As of 2005, development has stopped in favor of two successor systems, CapROS and Coyotos.

Key concepts

The overriding goal of the EROS system (and its relatives) is to provide strong support at the operating system level for the efficient restructuring of critical applications into small communicating components. Each component can communicate with the others only through protected interfaces, and is isolated from the rest of the system. A "protected interface", in this context, is one that is enforced by the lowest level part of the operating system (the kernel). The kernel is the only portion of the system that can move information from one process to another. It also has complete control of the machine and (if properly constructed) cannot be bypassed. In EROS, the kernel-provided mechanism by which one component names and invokes the services of another is capabilities using inter-process communication (IPC). By enforcing capability-protected interfaces, the kernel ensures that all communications to a process arrive via an intentionally exported interface. It also ensures that no invocation is possible unless the invoking component holds a valid capability to the invokee. Protection in capability systems is achieved by restricting the propagation of capabilities from one component to another, often through a security policy known as confinement.

The Shaftesbury Memorial Fountain is located at the southeastern side of Piccadilly Circus in London, United Kingdom. Moved after World War II from its original position in the centre, it was erected in 1892–1893 to commemorate the philanthropic works of Lord Shaftesbury, who was a famous Victorian politician and philanthropist.

The monument is surmounted by Alfred Gilbert's winged nude statue generally known as Eros. This has been called "London's most famous work of sculpture"; a graphical illustration of it is used as the symbol of the Evening Standard newspaper and appears on its masthead. It was the first sculpture in the world to be cast in aluminium and is set on a bronze fountain, which itself inspired the marine motifs that Gilbert carved on the statue.

The use of a nude figure on a public monument was controversial at the time of its construction, but it was generally well received by the public. The Magazine of Art described it as "...a striking contrast to the dull ugliness of the generality of our street sculpture, ... a work which, while beautifying one of our hitherto desolate open spaces, should do much towards the elevation of public taste in the direction of decorative sculpture, and serve freedom for the metropolis from any further additions of the old order of monumental monstrosities."
