אָבֵל חַיָּב בַּעֲטִיפַת הָרֹאשׁ, דְּהַיְנוּ שֶׁיְּכַסֶה רֹאשׁוֹ בְּטַלִית אוֹ בְּסוּדָר וְיַחֲזִיר קְצָתוֹ עַל פִּיו וְעַל רֹאשׁ הַחֹטֶם; וְהָנֵי מִלֵי שֶׁצָּרִיךְ עֲטִיפָה, בְּכָל הַיּוֹם. אֲבָל כְּשֶׁבָּאִין מְנַחֲמִים אֶצְלוֹ, מְגַלֶה רֹאשׁוֹ לִכְבוֹדָם. הַגָּה: וְיֵשׁ אוֹמְרִים שֶׁאֵין נוֹהֲגִין בִּמְדִינוֹת אֵלּוּ בַּעֲטִיפָה (הַגָּהוֹת מַיְמוֹנִי פ"ה) ; וְכֵן הַמִּנְהָג פָּשׁוּט, וְאֵין לְהַחְמִיר לְשַׁנּוֹת בַּמֶּה שֶׁלֹּא נָהֲגוּ אֲבוֹתֵינוּ.
A mourner is required to muffle the head,1M.K. 15a, derived from, ‘And cover not thine upper lip’ (Ez. XXIV, 17) whence we infer that everyone else is required to do this. i.e., to cover his head with a mantle or a piece of cloth [so that] part of it enfolds his mouth and the tip of the nose.2Tur on the authority of R. Hai Gaon, derived from the dictum of Samuel, ‘a covering that is not like the covering of the Ishmaelites (up to the lips) is not a mourner’s covering’ (M.K. 24a), and also from R. Naḥman who demonstrated this by covering himself up in his mantle up to the sides of the beard (ibid.). Only the nose and eyes remained exposed. Cf. also Y.M.K. III, 5(82d) top, ‘From this we learn that the mourner should cover his mouth. But let him cover his mouth from beneath? — So that they should not say, he has an ailing on his mouth (and therefore ties it up).’ On muffling the head with a mantle or a piece of cloth, cf. T.H. on the authority of R. Mattathias Gaon, derived from M.K. (ibid.) in the case of Abaye and R. Joseph. And this [matter, viz.,] that a mourner is required to muffle [his head] all day, applies [only when he is alone], but when comforters come to him, he uncovers his head out of respect to them.3On the authority of T.H., derived from Sem(H). X, 9. Cf. references in Sem. ibid. Gloss: Some say that in these countries we do not adopt the practice of muffling the head.4Hag. Maim. Yad, Ebel V, 19 — G. Cf. also M.K. 21a, Tosaf. s.v. אלו. For this leads to mockery among the Gentiles. Thus is the common practice, and one should not adopt the stringent view to make changes regarding a matter which our fathers did not practice.
