hat

capitis tegimen or tegumentum (general term, a covering for the head): petasus: causia (πέτασος, καυσία, a hat worn as protection against the sun, with a stiff brim, called causia when made with a high crown, as the Macedonians wore it; hence, also, causia would come nearest to our “hat.” Both the petasus and the causia were mostly made of felt, but, for the sake of lightness and cheapness, also of straw or rushes; ☞ Böttiger’s Furienmaske, p. 123, sq.). ☞ The pileus was a kind of covering for the head, made of felt, and without a brim, fitting close to the temples after the manner of our night-caps, and coming to a point at the top; hence called by Cic., apex; Vid: Cic., De Legg., 1, 1, 4; ☞ Liv., 1, 34, 8. It was worn on journeys, and during the “Saturnalia.” Hence it is very incorrect to translate “hat” by pileus. Wearing a hat, petasatus: to put a hat on anybody, petasum or causiam capiti alicujus aptare (after Lamprid., Anton. Diad., 5): to put on one’s hat, petasum (or causiam) sibi ad caput aptare or accommodare (after Lamprid., Anton. Diad., 5, and Cic., De Or., 2, 61, 250): to put one’s hat on again, tegimen (petasum, etc.) capiti reddere (after Liv., 1, 34, 10): to take off anybody’s hat, levare capiti tegimen or petasum (after Liv., 1, 34): to put a person’s hat on PROP. again, petasum capiti apte reponere (after Liv., 1, 31, 8): to take off the hat, tegimen capiti detrahere (general term): detegere caput (Suet.): to take off one’s hat to anybody, aspectu alicujus caput nudare venerationis causa (after Plin., 28, 6, 17); alicui caput nudare (after Sall., ap. Non., 236, 20; a salutation by taking off the hat, as with us, was expressed by the ancients by caput aperire or adaperire, to uncover the head before anybody; i. e., to remove the end of the toga, which was thrown over the head as a protection against wind and heat, as soon as a magistrate met one; Vid: Plin. and Sall., locc. citt., and especially, Sen., Ep., 64, 9, si consulem videro aut praetorem, omnia, quibus honor haberi solet, faciam; equo desiliam, caput adaperiam, semita cedam): *capite aperto salutare aliquem. The lining of a hat, *munimentum petasi or causiae interius. The brim of a hat, *margo petasi or causiae. Hat manufactory, *officina petasorum or causiarum.
