Barons [by Writ]
are such as are called to sit in parliament by their sovereign, without any precedent title.
The manner of erecting a baron by patent is as follows, he appears in court in his long robe and hood, attended by several persons of quality; two heralds walk before him, followed by Garter king at arms, holding the king’s writ; a baron, supported by two gentlemen of distinction, brings the robe or mantle, and so they enter the king’s presence, kneeling three times; then Garter delivers the writ to the lord chamberlain, and when in reading they come to the word Investivimus, the king puts on his mantle, and the writ being read, declares him and his heirs barons.
