* Ed. 1526 has [0d] 23;26,47h. This is an isolated printer's error: the entries before and after it are 2d 3;15,25h and 2d 3;37,45h, respectively.

is 1,2;22,28°. The corresponding entry in Table 93 is 1d 22;0,22h, after interpolation (1d 22;0,6h according to the worked example). Following the text, the difference is 0d 5;22,19h (= 2d 3;22,25h - 1d 22;0,6h) and it has to be subtracted from the time computed above (Aug. 15 at 15;49,7h). The result is Aug. 15 at 10;26,48h, which corresponds to the time in 1450 when the Sun was in the same position it had in the year of the epoch.

Table 94. Excess of revolution for the Moon and the ascending node in collected years

Nu, f. 97r: Lune et capitis in revolucionibus annorum collectorum Rc, f. 79v: Tabula lune in revolutionibus annorum Ed. 1526, ff. 388v-389r: Tabula [symbol for the Moon] et [symbol for the ascending node] in revolutionibus annorum collectorum

In this table there are six columns: see Table 94. The first is for the argument: collected years from 40 to 2000 at intervals of 40y. The entries in the other columns represent the time (in days, hours, and minutes), called [dies] superabundantes; the double elongation (in degrees and minutes), called centrum; the mean longitude of the Moon (in physical signs, degrees, and minutes), called motus; the mean argument of lunar latitude (in physical signs, degrees, and minutes); and the longitude of the lunar ascending node (in physical signs, degrees, and minutes). In Regiomontanus's copy the column for the argument of lunar latitude was omitted. The time displayed in column 2 is the excess in days over an integer number of anomalistic months; hence, the entries in this column do not exceed 27d 13;18,36h, which is the length of the anomalistic month used in Bianchini's tables (see Table 12, above). Tables 94 and 95 are similar in layout to Tables 12 and 13, but the entries differ, as will be explained below.
