Set the by-ginning of the degree that assendeth up-on the ende
of the 8 houre inequal; thanne wol the by-ginning of the 2 hous
sitte up-on the lyne of midnight. Remove thanne the degree that
assendeth, and set him on the ende of the 10 hour inequal; and
thanne wol the byginning of the 3 hous sitte up-on the midnight 5
lyne. Bring up agayn the same degree that assendeth first, and
set him up-on the orisonte; and thanne wol the be-ginning of the
4 hous sitte up-on the lyne of midnight. Tak thanne the nadir of
the degree that first assendeth, and set him on the ende of the 2
houre inequal; and thanne wol the by-ginning of the 5 hous sitte 10
up-on the lyne of midnight; set thanne the nadir of the assendent
on the ende of the 4 houre, than wol the byginning of the 6 house
sitte on the midnight lyne. The byginning of the 7 hous is nadir
of the assendent, and the byginning of the 8 hous is nadir of the
2; and the by-ginning of the 9 hous is nadir of the 3; and the 15
by-ginning of the 10 hous is the nadir of the 4; and the byginning
of the 11 hous is nadir of the 5; and the byginning of the 12 hous
is nadir of the 6. And for the more declaracion, lo here the

[DE ALIQUA FORMA EQUACIONIS DOMORUM SECUNDUM ASTROLABIUM.]
Tak thyn assendent, and thanne hastow thy 4 angles; for wel
thou wost that the opposit of thyn assendent, that is to seyn, thy
by-ginning of the 7 hous, sit up-on the west orizonte; and the
byginning of the 10 hous sit up-on the lyne meridional; and his
opposit up-on the lyne of midnight. Thanne ley thy label over 5
the degree that assendeth, and rekne fro the point of thy label
alle the degrees in the bordure, til thou come to the meridional
lyne; and departe alle thilke degrees in 3 evene parties, and take
the evene equacion of 3; for ley thy label over everich of 3 parties,
and than maistow see by thy label in which degree of the zodiak is 10
the by-ginning of everich of thise same houses fro the assendent:
that is to seyn, the beginning of the 12 house next above thyn
assendent; and thanne the beginning of the 11 house; and
thanne the 10, up-on the meridional lyne; as I first seide. The
same wyse wirke thou fro the assendent doun to the lyne of 15
midnight; and thanne thus hastow other 3 houses, that is to seyn,
the byginning of the 2, and the 3, and the 4 houses; thanne is
the nadir of thise 3 houses the by-ginning of the 3 houses that
folwen. And for the more declaracioun, lo here thy figure.
