_Forulus_ or _foruli_ occurs in the following passages. Suetonius, after describing the building of the temple of the Palatine Apollo by Augustus, adds, "he placed the Sibylline books in two gilt receptacles (_forulis_) under the base of the statue of Palatine Apollo"[73]; and Juvenal, enumerating the gifts that a rich man is sure to receive if burnt out of house and home, says, Hic libros dabit, et _forulos_, mediamque Minervam[74]. The word is of uncertain derivation, but _forus_, of which it is clearly the diminutive, is used by Virgil for the cells of bees: Complebuntque _foros_ et floribus horrea texent[75]. The above-quoted passage of Juvenal may therefore be rendered: "Another will give books, and cells to put them in, and a statue of Minerva for the middle of the room." The word _loculamentum_ is explained in a passage of Columella, in which he gives directions for the making of dovecotes: Let small stakes be placed close together, with planks laid across them to carry cells (_loculamenta_) for the birds to build their nests in, or sets of pigeon-holes made of earthenware[76]. In a second passage he uses the same word for a beehive[77]; Vegetius, a writer on veterinary surgery, uses it for the socket of a horse's tooth[78]; and Vitruvius, in a more general way, for a case to contain a small piece of machinery[79]. Generally, the word may be taken to signify a long narrow box, open at one end, and, like _nidus_ and _forulus_, may be translated "pigeon-hole." Seneca, again, applies the word to books in the passage I have already translated, and in a singularly instructive manner. "You will find," he says, "in the libraries of the most arrant idlers all that orators or historians have written--bookcases (_loculamenta_) built up as high as the ceiling[80]." _Pegmata_, for the word generally occurs in the plural, are, as the name implies, things fixed together, usually planks of wood framed into a platform, and used in theatres to carry pieces of scenery or performers up and down. As applied to books "shelves" are probably meant: an interpretation borne out by the _Digest_, in which it is stated that "window-frames and _pegmata_ are included in the purchase of a house[81]." They were therefore what we should call "fixtures." A _pluteus_ was a machine used by infantry for protection in the field: and hence the word is applied to any fence, or boarding to form the limit or edge of anything, as a table or a bed. _Plutei_ were not attached so closely to the walls as _pegmata_, for in the _Digest_ they are classed with nets to keep out birds, mats, awnings, and the like, and are not to be regarded as part and parcel of a house[82]. Juvenal uses the word for a shelf in his second Satire, where he is denouncing pretenders to knowledge:
