Commonly encountered mnemonics are often used for lists and in auditory form, such as short poemsacronymsinitialisms, or memorable phrases, but mnemonics can also be used for other types of information and in visual or kinesthetic forms.

The Romans valued such helps in order to support facility in public speaking.
The Greek and the Roman system of mnemonics was founded on the use of mental places and signs or pictures, known as "topical" mnemonics. The most usual method was to choose a large house, of which the apartments, walls, windows, statues, furniture, etc. To recall these, an individual had only to search over the apartments of the house until discovering the places where images had been placed by the imagination. In accordance with this system, if it were desired to fix a historic date in memory, it was localised in an imaginary town divided into a certain number of districts, each with ten houses, each house with ten rooms, and each room with a hundred quadrates or memory-places, partly on the floor, partly on the four walls, partly on the ceiling.
