المِرْزَمُ
1.
is a name of The right star [apparently
γ, i. e. Bellatrix,] in the left arm of
الجَبَّار [or Orion]. (Kzw. [Golius says, as on the authority of Kzw, that it is “ a star in the right shoulder of Orion: ” but Kzw says that this star (which is a of Orion) is called مَنْكِبُ الجَوْزَاءِ and يَدُ الجَوْزَاءِ; and then he mentions that in the left arm, as being called المرزم: whence it seems that Golius was misled by the omission of some words in a copy of the work of Kzw.]) And المِرْزَمَانِ, (S, K,) also called مِرْزَمَا الشِّعْرَيَيْنِ, (S,) is the name of Two stars [of which one is commonly known as B of Canis Major, and the other is apparently B of Canis Minor, though Golius says, on the authority of Ulugh Beg, that the former is in the right hind leg of Canis Major,] with the
شِعْرَيَانِ [by which latter appellation are meant Sirius and Procyon], (K,) or one of which is in [or by] الشِّعْرَى [commonly so called, i. e. Sirius,] and the other is in
الذِّرَاع [by which is meant الذِّرَاع المَقْبُوضَة, i. e. the asterism consisting of a and B of Canis Minor]; (S;) or one of them is
الذراع المقبوضة [mentioned above and the other is
الشِّعْرَى (q. v.) commonly so called]: thus says Ibn-Kunáseh: both are of the stars of rain: and sometimes the singular appellation (المِرْزَمُ) is used [apparently as applied to Sirius, or to Bellatrix, or perhaps to B of Canis Minor]. (TA.) نَوْءُ المِرْزَمِ [means The auroral setting of some one of the stars above mentioned; for it] is so termed because of its intense cold. (TA. See 1.) السَّمَاكُ المِرْزَمُ is another name for السِّمَاكُ الرَّامِحُ [The star Arcturus]. (Az and TA in article رمح. [This star neither sets nor rises aurorally in the cold season, nor is it one of the Mansions of the Moon; but it rises aurorally during “ the first of the rains, ” the autumnal rain, called الوَسْمِىّ.])
