Antik provides a foundation for scientific and engineering computation in Common Lisp. It is designed not only to facilitate numerical computations, but to permit the use of numerical computation libraries and the interchange of data and procedures, whether foreign (non-lisp) or Lisp libraries. It is named after the Antikythera mechanism, one of the oldest examples of a scientific computer known.
Antik provides the following:
- Organization of computation
- Grids (generalized arrays)
- Physical quantities
- Numerical output format
- Mathematical utility
- Three dimensional space
- Higher mathematics
Since it is intended to provide a foundation, Antik generally avoids more specialized definitions, with the intent that separate libraries using Antik, like GSLL will make those definitions. Where it is appropriate, convenient grouping of definitions made in other libraries are provided in higher mathematics.

Antik is usable now. The topics listed above are fairly complete, but documentation may be lacking. Added definitions for these topics and new topics may be forthcoming.
